How it works
Why compress images to 20 KB?
Tiny avatars, forum signatures and upload forms often reject anything over 20 KB. Squeeze a photo down while keeping it usable with smart quality search inside your browser.
How target-size compression works
This tool re-encodes your image repeatedly, searching for the highest quality that still fits under 20 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?
Shrinking to 20 KB runs entirely on your device. Your image is processed locally and never uploaded.
Batch compress images to 20KB
Squeeze a whole folder of images under 20 KB each in one pass. Free, private, batch ZIP, and everything runs locally in your browser.
Frequently asked questions
What fits in 20KB?
Small avatars, icons and signature images. Photos this small look best at low resolutions like 200 by 200.
Will a photo at 20KB still be usable
Yes for tiny avatars but expect softness. Resize to the target pixels first, then compress to 20KB for best appearance at small size.
Can I batch compress many images to 20KB without uploading
Yes. Add your folder, pick 20KB target, and compress together. Each image is searched locally for best quality under 20KB and you can download a ZIP.
