PDF editor · Online
Free-hand drawing with pen, highlighter and eraser — adjustable colour and thickness.
Sometimes the fastest annotation is just a pen. Underline, circle, cross out, sketch — directly on the page.
Drop it in the box or pick it from your device — up to 100MB, opened in about a second.
Pen for opaque strokes, highlighter for translucent ones, eraser to clean up. Adjust colour and thickness to taste and draw wherever the page needs it.
Strokes are undoable step by step, and everything runs in your browser — no copy of your document on our servers.
Three moments when a pen says it faster than any keyboard — and what each one asks of the page.
The council form arrives as a scan of a printed sheet: the boxes look like fields, but nothing clicks and no cursor ever appears. Cross out the option that doesn't apply, tick the two that do, write the amount in the blank space and date it by hand at the foot. Four strokes and it's back.
Twenty assignments come back as PDFs through the learning platform, and each needs the gestures a red pen makes on paper: underline the step where the reasoning breaks, cross out the wrong figure, tick the margin. Thin red pen for the corrections; wide yellow highlighter for the paragraph half the class misread.
Half the reviewing happens away from the desk: on a site visit, in a meeting, on the sofa. Open the page in the browser of an iPad or an Android tablet and mark with a finger or the stylus — free-hand tools shine on a touchscreen. Nothing to install, no account, even on a device that isn't yours.
Your strokes go onto a layer of their own and are written into the file you download, so they show up in any reader and on paper. The eraser only reaches that layer: the page's own text and graphics stay out of its way, and every stroke shares the editor's undo stack. Nothing is uploaded, and the file on your disk is never touched.
Purpose-built tools sharing one document, one canvas, and one undo stack. Pick a tool, do the edit, switch — without saving, reopening or jumping between sites.
Change the text inside the PDF — font, weight, colour and alignment — or insert new text wherever you want.
Insert, replace or crop. Adjust opacity, rotation and corner radius. PNG, JPEG and WebP.
Draw, type or upload your signature. We keep it in your browser to reuse across documents.
Rectangles, ellipses, lines, arrows and free-hand strokes with pen, highlighter or eraser.
Add notes and comments anywhere on the page. Great for reviews and feedback.
Rotate, duplicate, delete, merge another PDF, split, crop margins and reorder by drag.
Combine several PDFs into one. Drop in another file and place it exactly where you want.
Extract the pages you need into a brand-new PDF. Pick the pages, get a separate file.
Turn pages 90°, 180° or 270°. Fix sideways scans page by page or all at once.
Remove the pages you don't need and keep the rest. Select and delete in one click.
Trim margins or crop to a region. Preview the box and apply to one page or all.
Find and highlight any text in the document. Ctrl+F shortcut.
Password-protect the PDF. Pick AES-256, AES-128 or RC4 depending on the readers you need to support.
Shrink the file size. Three levels — lossless, balanced or maximum savings.
Cryptographically seal the PDF so anyone can verify it hasn't been altered after signing — tied to your verified account, checked on a public page.
We made deliberate decisions where most online editors hedge — privacy, speed, price transparency, scope. Here's what that looks like in practice.
Editing runs in your browser with WebAssembly, no server round-trip. AI does process your document — securely and only to answer you — but we never publish, share or use it for training. Only what you save is synced to the cloud. The only person who sees your file is you.
Most edits happen client-side in your browser, so they feel instant. When a step genuinely needs the server — heavy compression, encryption — it finishes in seconds. No polling pages, no «we'll email you when it's ready» rituals.
Editing is completely free — every tool, full quality, no watermark, no account required. The paid part is clear: to download your finished PDF you start a trial, and the plan also unlocks the cloud library. One flat monthly fee, and you cancel it yourself from your account whenever you want.
Text, signatures, images, pages, shapes, search, encryption and compression share the same canvas and the same undo stack. It runs on any modern browser — iPad and Android tablets included — with no extension, no native app, no installer trap.
Pens, strokes and what happens to them once you're done.
