Hey Indie Hackers 👋
I want to share a little tool I recently built — not a big startup idea, not an AI app, just something incredibly simple that solved a real annoyance for me.
It’s called pngtowebp.io, and it converts PNG images into WebP directly in the browser. No uploads, no accounts, no nonsense.
Why I built it
I’ve been working on a few projects recently (landing pages, micro SaaS tools, a blog redesign) and one pattern kept repeating:
PNG files were slowing everything down.
Lighthouse kept yelling at me.
Core Web Vitals looked bad.
Mobile loading was noticeably sluggish.
I know the solution was WebP, but most tools online were:
- Too slow
- Full of ads
- Required uploading files
- Hidden behind paywalls
- Or had weird usage limits I just wanted something fast, free, and private. So I built it myself. What the tool actually does Not much, honestly — and that’s the whole point. You upload PNG → it gives you WebP. The entire conversion happens locally in your browser, using:
His tool is very easy to use — you just need to upload your PNG file, and it will generate a WebP file for you. It’s extremely fast and convenient.
Here’s the live tool:

If you use it and something breaks, or if you have an idea to make it better, I’d genuinely love to hear from you.
Thanks for reading, and thanks IndieHackers for always being a place where small projects feel welcome. 🙌
