About Filenest
A nest is where things stay safe. Filenest is file tools built on one rule: your files never leave your device.
The problem with 'free online tools'
Most online converters and compressors work the same way: you upload your file to their server, they process it, and you download the result. That means your photos, scans, and documents travel to a machine you don't control — and you have to trust a stranger to delete them.
Modern browsers don't need any of that. They can read, compress, and convert files right on your device.
How Filenest works
Every Filenest tool runs 100% in your browser, using the built-in File and Canvas APIs. When you drop an image into the Image Compressor, the bytes are read and processed locally — there is no upload endpoint, no processing server, and no cloud queue.
You don't have to take our word for it: open your browser's Network tab while you work and watch nothing leave, or disconnect from the internet after a tool page loads and keep working.
Why it's free
Because your files never touch our infrastructure, our costs stay close to zero — we serve a static site and your device does the work. No accounts, no file-size upsells, no watermarks.
What's next
We started with image tools (compress and convert). PDF tools — merge, split, compress — are planned next, built on the same no-upload rule. If a tool can't be built fully client-side, we simply won't build it.
