We built 12 free tools that don't touch your files

Every developer has bookmarked one of those “free” utility sites — the image compressor, the JSON formatter, the QR generator. And every developer has run into the same three friction points: sign up with your email, hit a daily limit, or upload a confidential file to a server you don’t control.

We got tired of it. So we built tools.napdesigns.com — 12 utilities that run entirely in your browser.

What’s on it

• Image compression — MozJPEG, libavif, and oxipng engines. Same output as TinyPNG, none of the uploads.
• Image resize + convert + crop — the boring stuff, done fast.
• Background removal — client-side, no server round-trip.
• Favicon generator — SVG in, all favicon sizes out.
• PDF utilities — merge, split, compress.
• QR code generator — with logo embedding.
• JSON formatter + validator — pretty-print, minify, error highlighting.
• Color extractor — pull the palette from any image.
• Metadata viewer + stripper — see (and remove) EXIF, camera location, all of it.
• Watermark tool — add text or image watermarks in-browser.

Why it matters

All processing happens in your browser using WebAssembly. Your files never leave your device. That means:

• No servers to upload to
• No storage costs to pass on to you
• No daily limits
• No paywalls
• No accounts
• No tracking beyond basic pageviews

If you’re compressing a client’s confidential mockups, an internal PDF, or an image with sensitive metadata — it stays on your machine.

The stack

• WebAssembly binaries for the heavy image work (MozJPEG, libavif, oxipng)
• Static site — nothing dynamic to attack
• Zero third-party analytics on the tool pages

What’s next

We ship a new tool roughly every 2-4 weeks. Some ideas we’ve prototyped:

• SVG optimizer
• Video compressor (WebCodecs-based)
• Audio trimmer
• Font subsetter
• Base64 + hash utilities

If there’s a utility you keep opening a paid site for, tell us. Odds are it’s already in the queue.
