Can I change the existing text of the PDF?

Not directly: PDF text is laid out as fixed glyphs, not editable paragraphs. The usual approach is to cover the old text with “Cover” and type the new text on top. To rewrite whole paragraphs, convert it with PDF to Word.

Does it lose quality?

No. The pages are not re-rendered: your annotations are added as new vector content, so the original text stays selectable and images keep their resolution.

Is “Cover” the same as redacting?

It hides the content visually, but the text underneath is still in the file and can be copied. For truly confidential data, convert the result to images (PDF to JPG, then JPG to PDF).

Does it work on a phone?

Yes. The toolbar stays fixed while you scroll through the pages and every tool works with your finger. Use the “Scroll” mode to move around without adding anything by accident.

How many pages can I edit?

The first 80 pages are shown for editing. Longer documents can be edited too: pages beyond 80 are kept unchanged when you save.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.

Need to rewrite the content?

Annotations are ideal for small changes. If you need to rewrite paragraphs, convert the file with PDF to Word, edit it and turn it back with Word to PDF.
