About Toolifyer
Toolifyer is a collection of free web utilities with one unusual rule: your data never leaves your device.
The problem with most online tools
Search for “convert PNG to JPG” or “merge PDF” and you will find dozens of free services. Nearly all of them work the same way: you upload your file, a server converts it, and you download the result. Somewhere in that flow your holiday photos, signed contracts, medical scans or unreleased designs sat on a machine you do not control, governed by a privacy policy you did not read.
Most of those services are not malicious. But “we delete your files after an hour” is a promise, and promises fail — through breaches, misconfigured buckets, backups nobody purged, or a change of ownership. The only file that cannot leak is the one that was never sent.
How Toolifyer works instead
Modern browsers can do the work themselves. The File API reads your file into memory, and APIs like Canvas, TextDecoder and WebAssembly do the processing right there in the tab. Every Toolifyer tool is built on that foundation, which means:
- No upload. Your file is read locally and never transmitted.
- No account. There is nothing to sign up for and nothing to identify you.
- No limits. No daily quota, no file-size cap and no watermark on the output.
- No waiting. Without a round trip, results are effectively instant.
You do not have to take our word for it
This claim is testable, which is the point. Open your browser's developer tools, switch to the Network tab and use any tool on this site — you will see no request carrying your file. Better still, load a tool page, disconnect from the internet entirely, then use it. It keeps working, because everything needed is already running on your machine.
What we do collect
Nothing about your files or the text you type, ever. We run no trackers on tool content and no third-party analytics scripts that could read it. Standard web server logs may record requests for pages and assets, as they do on any website. The full detail is in our Privacy Policy.
What is next
We are steadily adding tools, always under the same constraint: if it cannot run entirely in your browser, we do not ship it. Have a tool you would like to see? Tell us.
