About Pixaru

Pixaru is a growing collection of 62+ free online tools that all share one principle: they run entirely in your web browser. You can convert and compress images, unzip files, edit PDFs, generate QR codes, run calculators and much more — without installing software, creating an account, or waiting for an upload.

Why we built it

Most online tools work by uploading your file to a server, processing it there, and sending the result back. That’s slow, it requires you to trust a stranger’s server with your documents, and it often fails on work or school computers where you can’t install anything. We thought the everyday tools people reach for — a quick image conversion, a file that needs unzipping, a calculator — should be instant and private by default.

Modern browsers are powerful enough to do all of this work locally, on your own device. So that’s how every Pixaru tool is built. Your files are read, processed and saved without ever leaving your computer or phone.

What makes Pixaru different

Private by design. Files are processed on your device, never uploaded. We can’t see them, store them or share them — because they never reach us.
No account, ever. Nothing to sign up for. Open a tool and use it.
No limits. No file-size caps and no daily quotas. Because the work happens on your device, you’re only limited by your own hardware.
Fast. There’s no upload and no download round-trip to a server, so most tools finish instantly.

How Pixaru is funded

Pixaru is free to use and supported by unobtrusive advertising. Ads let us keep every tool free, with no paywalls and no premium tiers. The ads are unrelated to the files you process, which always stay on your device. You can read exactly what data is and isn’t collected on our privacy page.
