Compressly didn’t start as a startup idea.
It started because I was tired of fighting image files.
I was working on a game project and constantly dealing with formats like .tga, .dds, and random texture exports that half the software ecosystem still treats like forbidden knowledge.
If you’ve touched game assets, modding, or 3D workflows, you probably know the routine:
Windows preview breaks
Transparency disappears for no reason
One tool opens the file but exports it wrong
Another requires a plugin from 2014
...and eventually you end up with 17 tabs open trying to convert one texture.
At one point, my workflow genuinely looked like this:
Export texture
Realize Photoshop hates the format
Open random GitHub converter
Download ancient desktop app
Accidentally install 3 toolbars 😅
Convert file
Compression settings ruined anyway.
And somehow in 2026, online image tools are even worse now. Everything has daily limits, “credits”, locked batch processing, forced uploads, signup walls, and compression paywalls... just to convert an image.
Meanwhile, they still don’t support half the formats developers actually use.
That’s when I had the thought:
Modern browsers are ridiculously powerful now. Why are we still uploading files to random servers just to convert images?
So I started building a small local-first tool for myself. That eventually became Compressly.
The whole thing runs 100% locally in your browser using WebAssembly (WASM), so: 🔒 Files never leave your device ⚡ Conversions start instantly (no server queues)
Basically: no uploads, no cloud dependency, and no waiting around.
I also wanted proper format support instead of “JPG to PNG and that’s it.” Right now it supports: WebP, AVIF, JPEG XL, PSD, DDS, TGA, HEIC, PNG, JPEG, SVG, BMP, and ICO.
The goal is pretty simple: Make image conversion fast, private, and actually usable again.
I'd love to hear your thoughts and what features you'd love to see next! 🙏
