How it works

Annotate a PDF in three steps.

Put your feedback exactly where it belongs: on the page, next to the thing it's about.

  1. 01

    Open your PDF

    Drop the document under review — a draft, a proposal, a design export. Up to 100MB, opened in about a second.

  2. 02

    Add notes where they belong

    Click anywhere on the page and write. Each note sits at the exact spot it refers to — no more "third paragraph, second line" descriptions in an email.

  3. 03

    Send the annotated file

    Notes travel inside the PDF, so whoever opens it sees your feedback in place. Everything ran in your browser — the document never left your device.

Use cases

What people annotate PDFs for.

Three moments when a remark has to sit on the page instead of travelling in a separate email.

Corrections on a print proof

The printer sends the proof of a 24-page catalogue and wants every change in one round. A caption is wrong on page 7, two prices are outdated, one photo has to be swapped. Marking each remark on the spot it affects means nothing gets lost between a phone call and a follow-up email.

Telling someone what to fill in

You send a tenancy agreement, an expense claim or a school form to someone who has never seen it. A note beside each field says which date goes there, where to initial and which box stays empty. The document explains itself, and it usually comes back complete the first time.

Notes that travel inside the file

The supplier, the client, the council office — nobody is signing up to a tool to read your remarks. The notes sit inside the PDF you send, so they open in Acrobat, in Preview or in the viewer on a phone, exactly where you left them. Nothing to install, no account, and no email trying to explain which paragraph you meant.

The editor runs in your browser through WebAssembly, so the page you are looking at is drawn by your own machine. Notes become part of the file only when you download it. The original on your disk is never touched, and moving, rewriting or deleting a note before that is one step you can undo.

Why us

Why choose our PDF editor?The details you'll feel every day.

We made deliberate decisions where most online editors hedge — privacy, speed, price transparency, scope. Here's what that looks like in practice.


Your files are yours.

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.


Fast by design.

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.


Free to edit. Honest about what's paid.

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.


One editor, not ten websites.

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.
