File tools that never see your files.

Resize passport photos, compress images, format JSON and more. Everything runs on your device, so your files are never uploaded to a server.

No uploadsNo accountOpen to inspection

Drop a file here

Photos, PDFs, text or JSON. You can also paste from your clipboard.

Or try a tool:
Quick Presets · One-Click WorkflowsClick any preset—or drop a file directly onto it—to process your file immediately. You can save your own presets inside any tool.
All tools

Pick a tool. Add a file. Download.

Every tool works the same way, so once you have used one you know them all.

How it works

Three steps, and none of them upload anything.

STEP 1

Add a file

Drop it on the page, choose it from your computer, or paste text. It opens inside this browser tab.

STEP 2

Adjust the settings

See a live preview as you change size, quality or format. Basic settings first, Advanced when you want control.

STEP 3

Download the result

Check the before and after, then save the file. Delete it from the tab with one click when you are done.

Why your files stay private

Each tool runs inside your browser tab, using your own computer. Our servers only send you the page. They never receive your file, because there is nowhere in the page to send it. While a tool works you will see a paper envelope close over your file. That is our way of showing that it stays sealed in your tab.

Check it yourself

Do not take our word for it.

Process something above, then look at these numbers. They are measured in this tab.

0

Network requests while processing

Counted from the browser's own request log around every run. It should stay at zero.

Hashing…

Fingerprint of this page's code

A live SHA-256 digest of the runtime code executing in this tab, verified alongside our WebAssembly module hashes.

connect-src 'self'

Blocked by the site's own rules

Enforced by a strict Content-Security-Policy header that blocks the page from contacting any external server.

Try it: open your browser's developer tools, switch to the Network tab, then process a file. You will see no upload. You can also switch off your internet connection first. The tool still works.
For developers and AI agents

The same tools, callable by code.

Every tool is described by one manifest. The page builds its settings from it, and AI agents (Claude, ChatGPT, Cursor) call the same tool through the Model Context Protocol. The same input always gives the same output, whether a person clicked or an agent called.

Frequently Asked Questions
Mes fichiers PDF sont-ils enregistrés sur un serveur distant ?
Jamais. Tout le processus s'effectue dans l'onglet de votre navigateur. Les PDF sont chargés en mémoire vive et assemblés en JavaScript sans appel réseau.
La résolution des polices et des tracés vectoriels est-elle altérée ?
Non. Le moteur préserve intégralement la netteté vectorielle, les polices intégrées et les annotations sans compression destructrice.
