How to edit a PDF
- Open your PDF: drop it in the box or click to choose it. Pages appear right here in your browser.
- Pick a tool from the toolbar:
- Text: click anywhere on a page and type. Great for filling in forms.
- Draw: sign or draw freehand with your mouse or finger.
- Whiteout: drag a box to cover content. Change the color to match a colored background.
- Highlight: drag over text to highlight it.
- Image: insert a logo, stamp or signature image.
- Adjust: with Select, drag anything to move it, use the corner handle to resize, and press ✕ or Delete to remove it. Use ↶ (or Ctrl+Z) to undo.
- Manage pages: rotate ⟳, move ↑ ↓ or delete ✕ pages, and use + Add PDF to merge another file.
- Click Download PDF.

Private by design
Most online PDF editors upload your file to their servers. This one doesn't. Your PDF is read, displayed and rebuilt entirely inside your browser using open-source libraries (Mozilla's pdf.js and pdf-lib). That makes it suitable for contracts, tax forms, IDs and medical paperwork.
Good to know
- Covering is not deleting: whiteout and boxes visually cover content, but the original text may still exist underneath and can sometimes be copied or extracted. For truly sensitive information, use a dedicated redaction tool.
- Fonts: added text uses Helvetica, which supports English and Western European languages.
- Password-protected PDFs can't be opened. Remove the password in your PDF reader first.
- Large files with hundreds of pages may be slow on older phones.
Frequently asked questions
Is this PDF editor really free?
Yes. There are no watermarks, page limits, sign-ups or trials. Everything runs in your web browser.
Are my PDFs uploaded to a server?
No. Your PDF is opened, edited and saved entirely on your own device, so it's safe for contracts, forms and other private documents. Nothing is sent to us.
Can I edit the existing text in my PDF?
Not directly — PDFs store text in a way that can't be reliably re-flowed in a browser. The standard workaround is to cover the old text with the Whiteout tool and type the new text on top with the Text tool. The result looks like an edit.
How do I sign a PDF?
Choose Draw, then sign with your mouse, trackpad or finger on the page. You can move and resize the signature afterwards. Alternatively, insert a photo or scan of your signature with the Image tool (a PNG with a transparent background looks best).
How do I merge PDFs?
Open your first PDF, then click "+ Add PDF" to add the pages of another file to the end. Reorder pages with the ↑ and ↓ buttons and remove any you don't need, then download.
Why do some characters show as "?" in the downloaded file?
The text tool uses Helvetica, a standard PDF font that supports English and Western European characters. Characters outside that set — such as Chinese, Arabic or emoji — can't be embedded and are replaced with "?".
