Uwarp: 500+ Free Browser UI Tools (No Signup)

Default design tools often mean installers, accounts, or uploading files to someone else’s server.

Uwarp is a free collection of 500+ browser UI tools—image and audio conversion, SVG, color, icons, mockups, and a few training games—meant to run locally in your tab. No signup for the tools themselves.

What you can do

A few examples from the homepage:

• Colour Contrast Checker — live WCAG ratio for foreground / background pairs
• Tints and Shades — build scales from any hex, export HEX / RGB / CSS / JSON
• Free SVG Icons — search Material Icons, Font Awesome, Heroicons, and more
• Image to Pixel Art — convert photos with grid size and palettes, download PNG
• MP3 Cover Adder — embed album art and edit ID3 tags in the browser
• GIF to Live Photo — turn GIFs into Live Photo–ready .mov without uploading

There are also lighter “recall” games (color, shape, sound) if you want a break that still trains visual / audio memory.

Built for makers, too

If you ship a product, submit a curated listing for manual review. Approved tools can show up as link-out pages under /curated. Free curated submission is open; paid featured placement is not for sale yet.

There’s also a separate hardware check playground at hardware-test.uwarp.design if you need quick browser device detection.
