The recommended workflow

Open the file, set up your task in the preview, check each affected page, and only then download. Keep the original so you can compare or start over when needed.

Limits to be aware of

The tool adds a new layer of content on top of the page; it does not guarantee that every piece of original text in a PDF can be edited like a Word document. Saving may also invalidate an old digital signature.

Data and sessions

The main operations are performed on your device, and files are not uploaded to CookPDF servers. The browser may save a cache or local draft to restore your session; you can clear the session in the interface or clear website data in your browser settings.

Frequently asked questions

Answers about capabilities, limits, and how files are handled.

Can I directly edit all existing text in a PDF?
Not always. The tool is best suited for adding new layers of text, images, and annotations. For original content that needs substantial rewriting, consider converting the PDF to Word.
Will the original layout be changed?
The original pages are preserved and new content is placed on top. You should still check positioning, fonts, and page margins before downloading.
What about PDFs with a digital signature?
Editing and saving a document may invalidate an existing digital signature. Keep the original and check the signature status after exporting the file.
Where are files processed?
The main editing operations happen on your device, and files are not uploaded to CookPDF servers.
