Compress Image Online Free
Shrink a photo or screenshot down to a smaller file size without installing anything or handing your image over to a server. Retouchr's Compress tool runs entirely in your browser tab, so the file you drop in never uploads anywhere.
Pick a quality slider for a quick shrink, or switch to target-size mode to aim for an exact KB or MB cap — handy for email attachment limits, web forms, or application uploads that reject large files.

FAQ
Does my photo get uploaded anywhere?
No. Compression happens with your browser's built-in canvas and image APIs, entirely on your device. Nothing is sent to a server.
What image formats can I compress?
JPG, PNG, WebP and most common image formats your browser can decode. The compressed output is a JPEG, which is usually the smallest for photos.
Will compressing lower the quality?
Some quality loss is expected with JPEG compression — that's how the file gets smaller. You control the tradeoff with the quality slider, and can preview the resulting size before downloading.
