How it works
Why compress images to 50 KB?
Email attachments and older CMS uploads often cap files near 50 KB. Get photos under the wire while keeping them recognizable with quality search in your browser.
How target-size compression works
This tool re-encodes your image repeatedly, searching for the highest quality that still fits under 50 KB. Choose the output format, JPG, WebP, PNG or AVIF, and the best match wins.
Which output format should I pick?
JPG is the safest default for photos. WebP keeps transparency and compresses well. PNG suits graphics and text. AVIF gives the smallest files in modern browsers.
Is compression private?
Target-size compression happens in your browser. The binary search for the best quality runs locally on your own machine.
Batch compress images to 50KB
Compress many images to under 50 KB at once for email or forms. Free, no sign up, batch ZIP, nothing leaves your device.
