The uploadis the slowpart.
Every other online tool sends your file to a server, queues it, and sends it back. We removed those three steps. Zero bytes leave this machine.
Built on the platform

Near-native speed for codecs and compression, in the tab

Four of them, working, right here
Not a carousel of screenshots. Type in the box and the output changes on the keystroke, computed by your own browser. Watch the request counter while you do it.

This is the product, not a picture of it
The panel beside this paragraph is the real word counter, running in your browser right now. Edit the text and the figures move as you type — and the request counter stays at zero, because there is nothing to send.
All 39 tools work this way. Open your browser’s network tab and use one; you will watch it do nothing.

The difference
What the upload actually costs you
Sending a file to a server is not one inconvenience, it is seven. The size cap, the queue, the account, the watermark and the retained copy are all downstream of that single decision.
We did not fix them one at a time. We removed the step they all come from.
How it works, and what it trades away| bram | Upload-based tool | |
|---|---|---|
| Where your file is processed | Your browser | Their server |
| Maximum file size | Your device's memory | Typically 5–100 MB |
| Queue at busy times | None — nothing is shared | Yes |
| Works offline | Yes, once loaded | No |
| Copy of your file retained | None exists | Per their policy |
| Account required | No | Usually |
| Watermark on output | Never | Often on free tiers |

What follows from it
Six things that stop being problems
None of these is a feature we added. Each is something that simply does not arise once the file stops travelling.
No queue, ever
Nothing is shared, so a busy Tuesday runs at the same speed as a quiet Sunday. There is no worker pool to be behind.
No size cap
The limit is your own memory, not a 50MB rule written to protect somebody's bandwidth bill. A 50-megapixel photograph is fine.
Works on a plane
Loaded once, every tool keeps working with the connection off. There was never a request to lose.
Nothing to leak
We hold no copy of your file — so there is none to lose in a breach, none to hand over on request, and none in a backup a year from now.
No account wall
No sign-up, no email, no verification step between you and a result. Open the page and work.
No watermark
On any plan, on any output. The free tier is not a demo of a better tier you have not paid for.
There is a cost too, and we would rather you heard it from us: what local processing trades away.
The method
How it stays private
Most online tools upload your file to a server, process it there and hand it back. That is a copy of your file on someone else’s disk, and a promise about what happens to it. We removed the promise by removing the upload.
It runs on your machine
Every tool here is JavaScript and WebAssembly executing in your own browser tab. The file is read from your disk, transformed, and written back — all locally.
Check it yourself
Open any tool, let the page finish loading, then turn off your Wi-Fi and use it. It still works, because there was never a request to make.
Nothing to leak
We hold no copy of your file, so there is none to lose, none to hand over, and none sitting in a backup somewhere a year from now.
Before you ask
The four we get most
Including the one about the catch, which there genuinely is one of.
All questions- Is it actually free, or free-until-it-isn't?
- Actually free. All 39 tools, unlimited, no account, no card, no expiry. They run on your machine, so metering them would be an artificial limit rather than a real one.
- How do I know my file is not uploaded?
- Check it. Load any tool, turn off your wifi, and use it — it still works. Or open your browser's network tab and watch nothing happen. That is a stronger guarantee than any policy we could write.
- What is the catch?
- Speed depends on your device, very large files are limited by your own memory, and a crashed tab loses the result because we hold no copy. Those are the real trade-offs and we would rather state them than have you discover them.
- Who is behind it?
- Tekhx, a small software studio. Paid plans fund it. It used to be advertising, and we removed that script because it contradicted everything else on this page.
Nothing to install. Nothing to sign up for.
Pick a tool and use it. If it turns out not to be what you needed, you have lost a click rather than an account.
