Every Free PDF Editing Tool You Get in Your Browser

A good PDF editor isn't one tool — it's a toolbox. The trick is having every one you need in the same place, without an install or an account in the way. The free online PDF editor packs all of the tools below into your browser, so you can mark up, write on and reshape any document in minutes — on desktop or mobile, with no sign up. Here's the full set.

Highlight, underline & strikethrough

The classic markup trio. Highlight a key sentence, underline a clause that needs a lighter touch, or run a strikethrough over text you want to flag for removal — each in any colour you like. For a deeper walkthrough of these, see the guide to highlighting and annotating a PDF online.

Add text to a PDF

Drop a text box anywhere on the page and start typing. You control the font, size, colour and weight — switch on bold, italic or underline to match the document. It's the fastest way to fill in a form, add a missing detail or write a comment, with no need to recreate the file from scratch.

Draw and sketch freehand

The Draw tool lets you sketch directly on the page — circle a figure, connect two ideas with a squiggle, or sign your name freehand. Pick a colour and a stroke width from thin to extra-thick, then draw with a mouse, trackpad or your finger on a touchscreen.

Shapes and arrows

Sometimes a clean shape says more than a scribble. Drop in a rectangle or circle to frame what matters, a line to divide a section, or an arrow to point a reader straight at the part you mean. Every shape takes your chosen colour and stroke width.

Sticky notes

Need to leave a comment without writing across the page? Drop a sticky note marker and tuck your message inside it. It's ideal for reviews and feedback — the note sits neatly on the page so the original text stays readable underneath.

Insert and place images

Add an image straight onto the page — a logo, a screenshot, a scanned signature or a stamp. Once it's in, you can drag it into position, resize it from any corner and rotate it to sit just right.

Fix mistakes fast

Editing is never one-and-done, so the cleanup tools are built in. Use the eraser to remove a single mark, undo to step back, or the select tool to grab any annotation and move, resize, copy or delete it. Keyboard shortcuts make it quicker still.

View, rotate, zoom & download

Around the editing tools sit the everyday essentials: flip through pages, zoom in for detail, rotate a sideways scan upright, and when you're done, download the finished PDF with every edit baked in — no watermark and no "create an account to save" step.

Every tool, free and in your browser

That's the whole toolbox — highlight, draw, type, shapes, notes, images and more, all free and all running in your browser. Open the editor to try them, or browse the full feature list to see what each one can do.
