Your files never leave your phone — everything runs in your browser.

Adds text, drawings, pictures, highlights and white boxes on top of the pages; the pages themselves are kept as they are, so existing text stays sharp and selectable. A white box covers what is under it, but that text is still inside the file: don’t use it to hide secrets. Added text is in English letters only. Takes PDFs up to 60 pages and 100 MB.

How to edit a PDF on your phone

  1. Tap Choose a PDF to edit and pick the file.
  2. Pick a tool: Text (tap the page, then type), Draw / sign (write with your finger), Picture (a signature, stamp or photo), Highlight or White box (drag over the area).
  3. Tap Move to drag things into place; drag the small round handle to resize. Use Prev / Next for other pages, and Rotate or Delete page if needed.
  4. Tap Save PDF, then Download, and open the new file to check it.

Tips

  • Correcting a word: put a White box over it, then add Text on top.
  • Clean signature: make a transparent one with our Signature maker, then add it with Picture.
  • File too big after editing? Shrink it with Compress PDF.
  • Download not starting? Downloads can fail in the built-in browser of a chat or social app. Open this page in Chrome or Safari.

Common questions

How do I add text to a PDF on my phone?

Choose the PDF, tap Text, then tap the place on the page where the text should go and type. Drag it to move it, and pick the size and colour. When you are done, tap Save PDF, then Download.

How do I sign a PDF?

Tap Draw and sign with your finger on the page, or tap Picture to add a photo of your signature (a dark signature on white paper works best; our Signature maker can make a clean transparent one). Move it into place, then save.

Can I change or delete text that is already in the PDF?

Not directly. This tool adds things on top of the page. You can cover old text with a White box and type new text over it, which looks right when printed or viewed. The old text is still inside the file underneath, so do not use a white box to hide passwords, account numbers or other secrets.

Is the PDF editor free?

Opening and editing a PDF is free, with no sign-up, so you can see exactly how it will look. Downloading the edited PDF needs a PDF download pass, a one-time payment of ₹29 for 7 days of unlimited downloads, or KTD Pro, which also covers the other website tools.

Is my PDF uploaded anywhere?

No. The page loads the PDF tools from this website, then opens, edits and saves your file inside your browser. The file is never sent to our server or anyone else.

Why can't I type Hindi or Bengali text?

The text you add uses a standard PDF font that has English letters, numbers and common symbols only. For Hindi or Bengali, write it with Draw, or add it as a Picture.
