What type of PDF edits can I make?

Last Updated: Jun 20, 2017 12:45PM CDT

DocHub makes it really simple and easy to edit and sign PDFs and other files, request e-signatures for any document, and quickly create PDF forms with its easy-to-use and common sense interface that's packed with a wide variety of PDF annotation, sharing, and collaboration tools that are mostly free to use. We also offer a DocHub Pro subscription plan for those who want to get even more out of DocHub and use it more often for business, academic, or any organizational or professional use. You can learn more about DocHub Pro at

The Tool Bar at the top of an open document in DocHub has a button for most of the PDF editing or annotation tools which are listed below unless noted as being in the Page Controls
 or Manage Fields  panels which can be toggled open or closed by clicking either icons on the left side of the Tool Bar, or if it's a Template, just click on  Edit Template  button in the upper right corner to display the Tool Bar and open the Fields Manager. You'll find some of these annotation tools in the File menu  in the upper right corner as well, and for many of the tools, you'll see some fine tuning controls to the right of the main Tool Bar when selected.

To find out how to upload a document or open files from within your Google Drive or Gmail or create a blank white document, click HEREThen, to begin to annotate your PDF in DocHub, simply select the tool you want to use on the Tool Bar and click anywhere on your document to add that type of annotation. You can add as many as you'd like and can always edit, move, or delete any of your annotations after they're on your PDF document.  

TEXT - Insert your own text anywhere on your document and choose from a variety of fonts, sizes, and colors including styles such as bold or italics for emphasis. All Text Tool windows have Snap-To-Grid assistance turned on by default for lining your text up perfectly with horizontal and vertical lines or the baselines of any embedded (permanent) text on your document. Use 'G' on your keyboard to toggle on or off. You can press Return or Enter on your keyboard while adding text to make a line break anywhere. To pre-determine how wide you want the text window to be and to force a line break at a certain width, you could frame a window instead by clicking anywhere on your document and hold the left-click button down while dragging the cursor to the desired width and then release the button. You can also line break anywhere within a framed Text Tool annotation window by pressing Enter or Return and make it wider by hovering your cursor over the right side of the box and click and drag to the right.

On the right side of the Tool Bar, you'll also see settings to justify your text to the left, right, or center of the Text Tool window and a drop-down menu to adjust the line spacing (increase or decrease the vertical space between rows of text).

DRAW - Use the free-form pen tool to draw lines, shapes, dots, and anything else you'd like in a variety of colors and brush sizes. You can click or tap the down arrow menu next to the Draw Tool button for assisted drawing and to change it from free-form drawing to perfect circles, rectangles, or straight lines. 

HIGHLIGHT - Choose from 6 different colors with yellow as default to frame a highlight box or to highlight only text on your document. You can use the down arrow menu next to the Highlight Tool on the Tool Bar to choose which one. The box shape (default) is for framing a highlight box window, and the one with A is for highlighting text that was already embedded on the PDF. 

COMMENT - Add your own comments in the form of a yellow paper icon with a small pop-up window for typing and displaying your text. 

WHITEOUT - Frame a white box over any content or areas of your PDF document that you'd like to cover up and can also add text or other annotations on top of the whited out area. 

CUSTOMIZABLE STAMPS - Choose from hundreds of shapes or icons to insert anywhere on your document with a customizable menu for quick access to your favorites. To choose and apply a stamp, just click on the drop-down arrow to the right of the Stamp tool, and you'll then see two drop-down menus appear for the Fill Color and Stroke Color to the right side of the Tool Bar which you can choose the color you want for your stamps and click anywhere on the document to add it. 

In addition to choosing the shape of a stamp, you can also change the color and size of each our
 added Snap-To-Grid assistance by default for lining them up perfectly with any horizontal or vertical lines (If you need to apply an X or checkmark to a non-editable PDF and have it look both professional and clean, this is the perfect tool to use for it. you can always resize a stamp after its been applied by hovering your cursor over it and dragging on the small square in the lower right corner of the floating annotation window when its active. Or simply click on it to make it the active one to edit.)

​We recently added over 600 new shapes or icons to the Stamp Tool menu from Awesome Font, and to adjust which ones appear in your main drop-down menu (your Favorites), just click on the downward arrow and click on "Customize...". Then, select any of the stamps in the long list of icons to add any to your convenient Stamps drop-down menu. Green highlight means the icon's been added, and you can click again on the stamp in that same Customize menu to remove it from your Favorites. 

INSERT IMAGEUpload your own photo files (i.e. JPEG, PNG, GIF, BMP, etc.) and place them anywhere on your PDF. You can also move the images around or resize them, the same as any annotation windows, after they've been added by dragging the blue bar at the top of the image window or resize them by dragging the lower right corner in or out (aspect ratio will be unlocked).

SIGN or INITIAL - Add your signature or initials to any PDF via drag/drop from the Sign menu or click/tap on one in the menu and then click/tap anywhere on your document to insert it. You can then move it around the document after inserting it, the same as all annotations you add to your PDFs in DocHub. To create an e-signature and save it to your private DocHub account, just click on Create Signature at the top of the Sign menu, and you'll see 4 tabs, one for each of the styles and choices listed below. You'll also see a toggle for creating a Signature or Initials to the right of these 4 tabs. Another place to do this is to go to and click on New for Signature or Initials.  
  • Phone - send an SMS text message to a smart phone with a link to draw a signature on its touchscreen without needing to login to DocHub. You'll also have the option to draw and save your Initials. To send one, just enter your phone number or your client's number and choose your country from the drop-down menu next to it (if not the USA) for the formatting and click Send. 
  • Draw - use your mouse, finger, or stylus to draw an e-signature.
  • Upload Image - upload a photo file of your handwritten signature or initials.
  • Type - choose from several fancy fonts that resemble a handwritten signature or S-Signatures that have your full name within forward slashes which are widely accepted as legally binding e-signatures (e.g. /s/John Hancock/).

DocHub saves copies of your signatures and initials in the Sign menu so that you can sign PDFs quickly and easily without needing to recreate your signature for every document you need to sign. If you ever want to remove one from the Sign menu, just click on Manage Signatures near the top of the Sign menu and use the Destroy button next to the one you want to delete. You'll also see today's date in the Sign menu which you can drag/drop onto your document to add a date stamp next to your signature.

If you are wondering how to request that someone else sign your PDF document, you can read our article for How do I send my PDF as a Sign Request? where you can add signature field(s) and enter their email(s) and send them a notification about a document that requires their electronic signature. Your signers don't even need to create a DocHub account to review and sign your PDFs. 

REORDER, ROTATE, DELETE, and ADD PAGES - Click on  on the left side of the Tool Bar to display or hide the Page Controls area which shows a thumbnail for every page of your PDF in a numbered, vertical column. You can delete or rotate single pages or multiple pages at once (hold Control or Command to select more than one) and click on the trash can  icon at the bottom of the column to delete the page(s) or click on  to rotate the page(s) 90 degrees clockwise (as many times as needed). ​To rotate all pages at once, click on the File menu  button in the upper right corner and hover your cursor over Actions > Rotate Pages and choose an option (90 degrees CW or CCW or 180 degrees). To reorder pages, you can simply click on any page and drag it up or down in the order. To add a new, empty page to the end of your PDF, use File menu > Actions > Append Pages and choose Append Blank Page. Or, you can click on the  icon at the bottom of the Page Controls column. 

MERGE OR COMBINE FILES - DocHub is also a PDF file merger app which lets you combine or merge or append multiple PDFs into one. First upload or open a file, and then you can append file(s) to it and add its pages to the bottom of the current document or add a blank page to the bottom if you'd like. To do this with an open file, just click on the File menu  button in the upper right corner and hover your cursor over Actions > Append Pages and click on Merge and Append File, and it'll bring up a window to choose a file from your Computer (select or drag/drop), Google Drive, Dropbox, OneDrive, or from a URL. Or, you can click on the Page Controls button and use the action buttons at the bottom of the layout of pages for your document. The Append option has a paper icon with a plus sign in the middle. You can combine and merge as many files as you'd like, and you can also rearrange, rotate, and delete any pages after the files have been combined (see the section above this one for more information on how to do those). 

FILL OUT FORMS - For applications, contracts, leases, or any other type of form, DocHub lets you fill out any text fields, tick checkboxes or radio buttons, select drop-down menu options, and add your signature or initials to any fillable PDF form. Just leave it on the default Pointer Tool (arrow) to fill in any pre-made forms. You can also fill out non-fillable forms (flattened with no active fields) by using the Text Tool or other Tool Bar items by clicking anywhere on your document while the tool is selected. Once the PDF form or non-fillable PDF form is completed, you can either download to computer, save it to Google Drive or Dropbox or OneDrive, share the URL, or email it as attachment. For true PDF forms with active fields, you can download or email it as-is with the fields still active and editable, or if you have a DocHub Pro account, you have the option to download or email a "flattened" version with the text and other form choices permanently embedded and finalized (where the annotations you added with DocHub are no longer editable). Please see our article for how to share or download your edited PDF for more details about each one of these sharing or saving options. 

CREATE FORMS (ADD FIELDS) - Use our Template Editor / Manage Fields interface to add every kinds of form field you need. This includes text boxes (one line or paragraphs), checkboxes, and drop-down menus as well as signature, initials, and auto-date fields to your template or document. For more information on how to do this, please see our articles for how to add fields to a PDF document and how to send a PDF as a sign request

POINTER TOOL (arrow) - The Pointer is the default and initially selected tool in DocHub and is a general use type of selection tool which is responsive to your document and the types of edits or form fields or checkboxes in the file. If you only need to adjust DocHub annotation windows that were added previously or add a signature or fill out a PDF form, then you can keep it on the Pointer Tool and do all of those things. This includes editing your text, moving around edit windows by dragging the blue bar at the top of each one, resizing edit windows by dragging the lower right corner, deleting edit windows by clicking on the X, adding a signature from the Sign menu, and typing in form fields or checking boxes. The Pointer tool will also let you copy any pre-existing text on your document. 

To print a document or template while viewing it, just click on the Print icon near the left side of the Tool Bar or click on the File menu  button in the upper right corner and choose Print...

You can also Zoom In  or Zoom Out  by clicking on those buttons on left side of your document below the tool bar.

Make an editing mistake? Or, would like to A-B a new edit and show before and after? DocHub also has Undo  and  
Redo options on the tool bar with the keyboard shortcuts Control-Z and Control-Y on a PC or -Z and -Y on a Mac (Z = Undo and Y = Redo). 

To view an Activity log for your PDF document while viewing it, just press A on your keyboard to toggle open the Activity panel or click on File menu > Actions > Toggle Activity Panel (A). This displays or hides a panel to the left of your document showing a log for each and every action taken on your document including the date and time of the activity by you or any other users you've granted sharing permissions to the collaborate on the same file or if you emailed it as a Sign Request (requested an e-signature and/or a form to be filled). 

If there are any other PDF editing tools that you would like to see added to DocHub or have any feedback about the ones above, we'd love to hear your thoughts! You can do so by Emailing Us or Posting a Public Question.
