Frequently asked questions
Can I change the existing text in a PDF?
PDFs do not store text in editable paragraphs, so changing it directly is unreliable. The standard approach, used here, is to cover the old text with white-out and type the new text on top.
Does white-out really remove the text underneath?
It covers it visually on screen and when printed, but the original text is still in the file and can be copied or found by search. For private details, white it out and then flatten the PDF into images with Flatten PDF.
Which fonts can I use?
Sans serif, serif and monospace, in regular or bold. These are the standard PDF fonts, which cover English and Western European letters. Other alphabets, such as Urdu or Arabic, are not supported for new text yet.
Can I add a signature?
Yes, as an image, but Sign PDF is easier: you can draw your signature and place it in one step.
How do I move or delete something I added?
Drag it to move it. Hover over it and press the red × to remove it, or press Undo to remove the last item.
Can I edit scanned PDFs?
Yes. Scanned pages are images, so you can white out, highlight and add text on top in the same way.
Will the original layout change?
No. Your additions are placed on top of the existing page, and everything else stays as it was.
Can I edit several pages?
Yes. Use the arrows to move between pages; everything you add on each page is saved together.
Is my PDF uploaded?
No. Editing and saving happen in your browser, so the document stays on your device.
How this tool works. These PDF tools run entirely in your browser using two widely used open-source libraries: PDF.js, the PDF engine built into Firefox, to read and render pages, and pdf-lib to create and edit files. Each tool is tested with typed documents, phone scans and photo-heavy files before it goes live, and nothing you open is sent to a server.
