Why compress an image to 20KB?
Many websites and forms enforce strict upload limits — exam applications, visa portals, job sites and government forms often reject any photo over 20KB. This image compressor reduces your picture to 20KB or less automatically, so your upload is accepted the first time.
The compressor works in three smart layers: it re-encodes your image with an efficient encoder, lowers quality only as much as needed, and reduces resolution only when a strict size target demands it. That's how it can shrink image size aggressively while protecting how your photo looks.
Compress images without losing quality
Compression doesn't have to mean ruined photos. For most pictures, you can reduce image size by more than half with no visible difference. Our photo compressor shows you a before-and-after comparison so you can see exactly what you're getting — and a strength slider lets you choose your own balance between file size and quality, then re-apply as many times as you like.
Everything runs privately in your browser: your photos are never uploaded to a server, which also makes this one of the fastest picture compressors online.
