PDF editor not working? Here's how to fix it
Most issues are small and fixable in seconds. Work through these in order.
1. The tool won't load
Reload the page or open it in a fresh tab. If an extension blocks scripts, use private (incognito) mode — the editor needs JavaScript, which is on by default in every modern browser.
2. The file won't upload
Check the format and size. Edit PDF accepts PDF up to 50 MB. If a file is larger, split or compress it first, and confirm it's really a PDF (a renamed file from another type is rejected).
3. I can't change existing text
If the PDF is a scan, existing text is an image and can't be edited as characters. Add text boxes and signatures over it instead — or use a text-based source PDF when you need to change wording.
4. The signature or text won't go where I want
Drag it into place using the preview so you can see the exact position. If it snaps oddly, zoom in for finer control.
5. Nothing downloads
Check your browser's download location and pop-up/file settings. Many browsers quietly block automatic downloads from new sites.
Still stuck?
Try a different current browser (Chrome, Firefox, Safari, Edge). Because the tool runs locally, a fresh environment usually resolves remaining edge cases.
Verdict
Most Edit PDF problems are solved by a reload, a supported file, a text-based source for character edits, or a private window.
