A few months ago I kept running into the same frustrating problem:

Upload portals rejecting my images because the file size was just slightly over the limit.

Especially on: It was frustrating re-compressing the same image over and over just to reduce a few extra KB.

Most image compressors either:

So I ended up building a browser-based image compression tool focused on one specific thing:

Compressing images to an exact KB target while keeping the quality as usable as possible.

A few things I focused on while building it:

One thing I didn’t expect during development was how difficult ultra-low KB targets become.

For example:

I also realized metadata removal can make a surprisingly big difference for photos taken on modern phones.

The project is still improving, but it has already become one of the tools I personally use most often.

I’m still improving it, but it has already become genuinely useful for handling strict upload limits:
