If you are unable to open a PDF or other files to edit or sign from within Google Drive or Gmail or when uploading directly on our site on the New Document or New Template upload pages, first take note of the wording of the error for information about why it can't be uploaded. The error will usually provide you with the reason why your file is not being accepted.
If you get a message about the file exceeding a size limit, check to make sure your file is under 30 MB and less than 1,000 pages by checking the file Properties or using Get Info and once you've verified that the file is not too large, simply try uploading the same file again and if it still fails, you should try a different web browser to see if it works.
If you receive a different error message or are still getting one about exceeding a size limit when you are certain it's under the limits, you should try uploading a different file of the exact same file type and similar file size, if possible, to help determine whether it may be an issue specific to that one particular file.
If you don't feel comfortable attaching the file to your case, please be sure to at least provide us with details about the file including its size, file type or extension, the number of pages, where the file originated (what app or device first created it?).
