Edit PDF — Add Text, Images, Boxes & Highlights

How to edit a PDF in your browser

1. Choose the PDF and pick the page you want to work on. The page renders at full clarity in the box below.
2. Pick a tool: Add text (type it, set size and color), Add image (a logo or photo, placed at full resolution), Box (an outlined or lightly filled rectangle) or Highlight (a semi-transparent yellow bar).
3. Click anywhere on the page preview to place the item. Every placement shows up instantly on the preview; list entries below it let you remove any of them.
4. Switch pages to edit several, then hit Apply & Download. The result is a brand-new PDF with your additions baked in — the original file stays untouched on your disk.

What does "edit" mean for a PDF?

PDF is designed to be a fixed layout — the honest toolset for it is additions, not reflow. This editor adds precisely the things people actually need on a fixed page: a note, a name, a logo, a border around a field, a highlight over a line. It does not re-typeset your document, and it will not pretend to.

Where exactly does text get placed?

The click point becomes the text's baseline start (top-left reading position). If you want text inside an empty form field, click where the line's left edge is. The preview shows the exact position that will be written, so what you see is what the downloaded PDF contains.

Does it work with scanned or image-only PDFs?

Yes — the editor works on whatever the page renders as, including pure scans. What it cannot do is change the scanned content itself (that would be image editing); it layers new content on top, which is exactly what filling in a scanned form requires.

Privacy of the editing session

The file, your additions and the rendered preview all live in the tab. Nothing is uploaded at any point, the downloaded file is built locally from your original plus your placements, and closing the tab discards everything.

FAQ

• Is my file uploaded to a server? No. The tool runs entirely in your browser — your file never leaves your device. You can verify it yourself: open the network panel and there is no upload request while you work.
• Do I need an account, and is it free? No account and no cost. It is free to use — no signup, no paywall, no daily limit.
• Which browsers does it work in? Any modern browser — Chrome, Edge, Firefox and Safari — on desktop or mobile.
• Is there a size limit? There is no server-side limit because nothing is uploaded. Practical limits come from your device's memory, which comfortably covers normal documents and photos.
• Does it work with encrypted PDFs? Standard PDFs work in every tool. If a file is password-protected, Unlock PDF opens it for you when you have the password, and Protect PDF applies a new 256-bit AES password. No tool bypasses encryption without the key.
