If you are unable to open or upload a PDF or other files to edit or sign from within Google Drive or Gmail or when uploading directly on our site, first be sure to read the wording of the error for information about why the file can't be uploaded. The error will usually provide you with the reason why your file cannot be uploaded.
If you are just getting a blank page, try clearing your cache.

Size limit error
If you get a message about the file exceeding a size limit, make sure your file is under 30 MB and less than 1,000 pages by checking the file Properties or using Get Info. Once you've verified that the file is not too large, simply try uploading the same file again. If it still fails, try a different web browser.
If you receive a different error message or are still getting one about exceeding a size limit when you are certain it isn’t, you should try uploading a different file of the exact same file type and similar file size (if possible). This can help determine whether it may be an issue specific to that one particular file.
If you find that other files are able to upload and only the original file is encountering an upload error, please contact our support team.
For a document-specific issue like this, it would be incredibly helpful to our investigation if you could attach the problematic file(s) to your support case using the Add File button near the bottom of our support form. This would also help resolve the issue faster.
We assure you that DocHub takes privacy very seriously, and attaching your document to your support case would only be used for troubleshooting and debugging purposes and to help isolate what may be causing the issue you’ve reported. Your file(s) and any data in it would not be shared with anyone. You can view our official Privacy Notice page and an article about it via the links below:
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, and where the file originated (what app or device first created it?).
If your document was successfully uploaded but the text looks distorted, this issue can be fixed by disabling Hardware acceleration in your web browser. See the following articles for how to do so:
Then, please try viewing the document in DocHub again and checking if there is any distortion moving forward. If the issue persists, please contact our support team so we can investigate it further.
