Exact-size compression should be honest

ImageCompressor.pics is an independent web utility for people who need an image below a real KB or MB limit, without sending that image to a processing server.

Why we built it

Many upload forms publish a maximum file size but ordinary image tools only expose a quality slider. Users must export, inspect, adjust, and try again. The problem gets worse with batches or with very small limits such as 20KB and 50KB.

This site works backward from the byte limit. It measures each candidate output, keeps the best quality that fits, and reduces dimensions only when quality changes are not enough.

Our product principles

Private architecture

Image files remain in the browser. The site has no image upload endpoint.

Measured claims

A result is marked under target only after its actual Blob size is checked.

Useful quality

The engine searches quality before reducing dimensions and never upscales a source.

No artificial friction

No account, watermark, hidden upload, or daily usage quota is required.
