about.

45 free browser tools. No uploads. No signup. No paywall. Built by NAP Designs — one person, in the open.

Why this exists

Every "free" online tool has a catch. Daily limits. Upload caps. A "Pro" tier you hit faster than expected. Your files sitting on someone else's server in another country, waiting for a data breach.

I didn't want that. So I built this.

Every tool here runs entirely in your browser. Not "mostly." Not "usually." Every byte of computation happens on your device. You can open DevTools' Network tab and confirm: zero POST requests when you compress an image, hash a file, or decode a JWT.

Who built it

Pratham (@nap.codes) — a designer + engineer who runs NAP Designs. I make web experiences and physical products; the tools started as scripts I used daily and turned into a shared toolkit.

What it runs on

• WebAssembly — for image codecs (MozJPEG, WebP, AVIF, jsquash) and PDF operations (pdf-lib, pdf.js)
• Native browser APIs — crypto.subtle for hashing, crypto.getRandomValues for passwords, Canvas for graphics, WebCodecs for video
• ONNX Runtime Web — for the AI tools (cutout, product, watermark-remover, tagger). Models download once, cache in your browser, run locally.
• Static HTML — no framework, no bundler magic. View source and understand.
• PWA — install as an app, run offline once installed

What it will never do

• Upload your files to a server
• Store your files in a cloud
• Show ads
• Sell your data (there is no data to sell)
• Add a "Pro" tier that gates the actual utility
• Watermark output files
• Rate-limit you based on IP

What it might do

• Load privacy-friendly page-view analytics (Plausible — no cookies, no personal data). You can turn this off in settings — floating ⚙ button — with a single toggle.
• Save your preferences (theme, pinned tools, recipes) in your browser's localStorage. Never leaves your device.

Roadmap

See the changelog for shipped versions. New tools go up roughly every 1-2 weeks. Feature requests and bug reports welcome via napdesigns.com.
