Nothing leaves this device
A PDF workspace that lives on your device, not in the cloud.
Edit, stamp, sign, merge, number and batch-process PDFs in your browser. No upload, no account, no limits — and it keeps working when the internet does not.

Nothing is uploaded. Free, and there is no account.
22 tools in total
Editing, automation and inspection — every one runs entirely in your browser.
Everything it does
Three things you do to a document.
22 single-purpose tools, plus a full editor when you need to do several at once.
Automate
Apply the same treatment to everything.
- Save your steps as a workflow
- Run it on a folder of files
- Bates numbering and page numbers
- Stamps with automatic dates
- Watermarks and headers
Inspect
Know what a file carries before you send it.
- Metadata naming the author
- Embedded scripts and attachments
- Text hidden off the page
- Earlier revisions left behind
- Remove what you find
Two things that make it different
Stamps you design, and workflows you can email to a colleague.
Stamp Studio
Design a stamp the way you would order a rubber one — layout, frame, ink colour, letter spacing, and a distress slider so it reads as physically inked when the document gets printed and scanned back in.
- Variable fields like
{{date}}and{{counter:4}}, resolved when the stamp is placed - Circular seals, ribbons, framed boxes and logo layouts
- Export as a transparent PNG for Word, email or anywhere else
- Bundle a set into a
.stampspack and send it to your team
Workflows
Record the sequence of things you do to every document that lands on your desk, save it as a file, and run it on one PDF or a folder of two hundred. It is a file, not an account feature — so it travels.
Workflow "Invoice intake"
1. Remove blank pages
2. Bates number INV-{{counter:4}}
3. Stamp PROCESSED {{date}} bottom-right
4. Header {{filename}} — {{date}}
5. Rename {{bates}}.pdf
- Drop a folder in, get a ZIP out, all processed on your machine
- Batch is unlimited because the processing happens on your machine
- Share as a
.workflowfile: no sync, no seats, no admin
What you get
The ordinary things, done properly.
A differentiator is worthless on top of a shaky core. These are table stakes, held to the same standard as everything else.
Read and navigate
Thumbnails, zoom, sharp on any screen.
Reshape the document
Reorder, rotate, delete, merge, split.
Mark it up
Text, highlights, ink, shapes, signature.
Fill forms
Detected fields, filled and flattened.
Number and label
Bates, page numbers, headers, watermarks.
Export and verify
Reopened by a second engine before you see it.
The promise, stated precisely
Nothing here is a promise you have to take on faith.
Wondering exactly what it does and does not do? That is set out plainly on the About page, alongside how it compares with a tool that processes your file on its own servers.
Install it once and it works with the network unplugged.
No installer, no update service, no account. Load it a single time and it keeps running on a plane, in a facility with no connection, or anywhere the signal gives out. IT departments tend to like a tool that cannot phone home.

Questions
Straight answers
Are my PDFs uploaded to a server?
No. Every operation — opening, editing, stamping, merging, exporting — runs in your own browser using JavaScript. There is no upload step, so no document is ever transmitted. The site is static files on a CDN.
You do not have to take that on faith. The page sets a Content Security Policy of connect-src 'self', which means your browser itself will refuse any attempt to send data elsewhere. Open your network tab and watch: after the app loads, there is no traffic.
Is it really free? What is the catch?
It is free, with no page limits, no file size tiers, no watermarks and no account. There is no catch, but there is a reason: because nothing is processed on our servers, serving you costs almost nothing. Every competitor pays for CPU to convert your file, so every competitor has to meter you. We do not.
Does it work offline?
Yes. Load the page once and it keeps working with the network disconnected — on a plane, in a secure facility, on a site with no signal. You can also install it to your desktop or home screen, so it opens in its own window with no connection at all.
Can it edit the existing text in my PDF?
Yes, a line at a time. Pick the Edit text tool and click any words on the page: they are covered in the colour of the paper behind them and an editable copy appears on top in matched type, size and colour. It exports as real embedded text, so it stays searchable and selectable.
What it does not do is reflow the surrounding paragraph. A PDF usually embeds only the glyphs it already uses, so rewriting its content stream can leave a new character with no glyph at all — which is why even the most expensive desktop editors mangle this. Replacing a name, a date, a reference number or a form entry works perfectly. Re-wrapping a justified block of body copy does not, and we do not offer it.
Can it permanently redact text?
Not yet, and we would rather say so than ship a black rectangle and call it redaction. Drawing a box over text leaves the text underneath, fully selectable — that mistake has embarrassed governments and law firms with real consequences. True redaction that removes content from the page structure and then verifies the removal is on the roadmap. Until it lands, the honest answer is no.
What happens to my documents when I close the tab?
They are gone. Your file is held in the tab's memory while you work and is released when the tab closes. The only things kept in browser storage are your saved stamps and your recently used tools list, neither of which contains document content, and you can clear them at any time.
Which browsers and devices does it work on?
Any current browser — Chrome, Edge, Firefox or Safari — on Windows, macOS, Linux, Android and iOS. The interface adapts to phone screens, though heavy work on very large files is more comfortable on a laptop where there is more memory available.
How do I know the privacy claim is true rather than marketing?
Three ways, none of which require taking our word for it. The Content Security Policy on the editor is enforced by your browser rather than by us, and permits no other origin at all. The app carries a Local Processing Monitor listing every request the page has made, built on the browser's own performance API. And you can disconnect from the internet and keep working — software that needed to transmit your file could not.
