Free browser-based developer tools I built for everyday frontend work

I built a small collection of free web tools for common frontend/dev tasks:

https://0918.us

Tools include:

• Image converter, compressor, resizer, cropper

• JSON formatter

• Base64 text/image converter

• URL encoder/decoder

• Hash and UUID generator

• CSS gradient / box-shadow / clamp generators

• YouTube to MP3/MP4 converter for content you own or have permission to download

Everything runs in the browser where possible, no sign-up required.

I originally made it for my own workflow, but I’m trying to improve it and would appreciate feedback from other developers.

If you have suggestions for useful tools to add, UX fixes, or SEO/content ideas, I’d love to hear them.
