I Built Pixelquil: Free Browser Tools for SVG, JSON, and Technical SEO (No Signup, No Uploads)

I kept running into the same small problem while working on client sites and my own projects: I needed a quick tool to fix a broken SVG, format a messy JSON blob, or check a robots.txt file, and every free option online either wanted me to sign up first or uploaded my file to their server before showing me anything.

So I built Pixelquil, a small toolkit that runs entirely in the browser. No account, no upload, no server processing your file. Whatever you paste in stays on your device.

What's in it right now

SVG tools

  • SVG editor and viewer
  • viewBox fixer (for that classic "my icon is cut off" problem)
  • Color palette extractor

Developer tools

  • JSON formatter and validator
  • JWT decoder
  • Regex tester and builder
  • UUID and hash generators
  • Password and passphrase generator
  • Case converter, Unix timestamp converter, text diff checker, cron expression parser, and a few more

SEO tools

  • robots.txt tester
  • AI crawler access checker

Why client side only

Two reasons, honestly. First, privacy. A lot of the files people run through these tools come from client work, and I did not want to be the reason someone's unreleased product SVG or a JWT with real claims in it ends up sitting on some server's logs. Second, speed. Client side tools respond instantly. No upload spinner, no waiting on a request round trip for something that should take milliseconds.

What's next

More tools are getting added as I run into more of these small tasks myself. If you have a tool you keep wishing existed but never bothered to look for, drop it in the comments. That is genuinely how most of the current list got built.
