Most "free online tools" aren't really free — the cost is your file. You drop a PDF onto someone's server and hope their retention policy is what their marketing page claims.
Toolbelt works differently. Every tool on this site runs entirely inside your browser tab. Your files don't move. There's no account system, no upload queue, no Pro plan gating a 15 MB ceiling. It's the same code that would run locally if you installed a desktop app — just shipped as a web page so you can use it without installing anything.
What's live today
- PDF: merge, split, rotate, compress — all lossless, no watermark.
- Image: compress, resize, convert (JPG ↔ PNG ↔ WebP) — canvas-based encoding.
- Generate: QR codes (URL, text, WiFi) — PNG + SVG export.
- Developer: JSON formatter — prettify, minify, sort keys.

Why "client-side" matters — and how to verify it
Anyone can write "we care about your privacy" on their homepage. The interesting question is whether you can verify it, in under a minute, without trusting a marketing page.
That check is the whole product philosophy. Every guide on this site walks you through whatever tool it's about — but also explicitly shows you how to confirm the tool does what we say.
What's next
Over the next few weeks we'll ship in-depth guides for each live tool, each answering the real question people search for instead of repeating vendor marketing. The first two are already live: compressing PDFs without losing quality, and resizing images without quality loss.
