Edit PDF Online Free

Edit PDF is a free, browser-based PDF editor that lets you annotate and modify PDF documents by adding text boxes, drawing shapes, and sketching freehand directly on any PDF page. No software download, no subscription, no signup — just open the tool, upload your PDF, and start editing instantly in your web browser.

What Can You Do with the PDF Editor?

Our Edit PDF tool gives you a powerful Fabric.js canvas overlay on top of your PDF pages. You can add custom text in any position on the page, insert rectangles and shapes to highlight or block sections, draw freehand with a pen tool for annotations or signatures, and navigate between pages to edit different sections of multi-page PDFs.

This is ideal for filling in PDF forms that are not interactive, adding comments or review notes to documents, marking up technical drawings or architectural plans, inserting missing information into scanned PDFs, and highlighting key sections before sharing.

How the PDF Editor Works

When you upload a PDF, our tool uses PDF.js to render each page as a high-resolution canvas. Fabric.js then creates an interactive editing layer on top of the rendered page, allowing you to place and manipulate objects freely. When you click Process, all your edits are flattened onto the PDF pages using PDF-lib, and the resulting file is saved for download.

Because everything runs in your browser, your documents are completely private — they never leave your device. This makes it suitable even for sensitive business, legal, or personal documents.

Frequently Asked Questions

Can I edit the original text inside the PDF?
This editor adds new elements on top of the PDF. Changing the original embedded text requires a full desktop PDF editor like Adobe Acrobat.

Will my edits be saved permanently?
Yes. When you click Process, all edits are permanently flattened into the downloaded PDF.

Is it compatible with all PDFs?
It works with most standard PDFs. Encrypted or heavily protected files should be unlocked first using our Unlock PDF tool.
