How to edit a PDF for free

Upload your PDF, click any page to open the edit view, then use the toolbar to add text, images, or annotations. When done, click Download — your edited PDF saves instantly. No sign-up, no cost, completely free.

Add text to a PDF online

Need to fill in a form or add a note? Open the PDF editor, select the text tool, click anywhere on the page and start typing. Adjust font, size and colour before saving. Works on any PDF — scanned or digital.

Compress PDF without losing quality

Large PDFs slow down email and uploads. Use the Compress tool to shrink file size by up to 80% while keeping text sharp and images readable. No file-size cap for browser-side compression.

Split and merge PDF files

Extract specific pages or combine multiple PDFs into one. The Split tool lets you pick exact page ranges; the Merge tool accepts multiple files in any order. All processing happens in your browser — your files never leave your device.

Frequently Asked Questions

Is this PDF editor really free?

Yes — all tools are completely free. There are no premium tiers, no hidden fees, and no watermarks added to your files.

Do I need to create an account?

No account or login is required. Just upload your PDF and start editing immediately.

Is my PDF secure? Are files uploaded to a server?

Most operations (compress, rotate, split, merge, add text) run entirely in your browser using PDF-lib and PDF.js. Your file never leaves your device. For operations that require server processing, files are deleted immediately after download.

Can I edit a scanned PDF?

You can add text overlays and annotations on top of scanned PDFs. For full OCR text recognition, use the Edit PDF tool which supports text layers on scanned documents.

What is the maximum file size?

Does it work on mobile?

Yes. The PDF editor is fully responsive and works on iPhone, Android, and any modern mobile browser — no app download needed.
