How it works
Why compress images to 150 KB?
Visa paperwork, loan applications and vendor portals frequently allow only 150 KB. Fit documents and photos to their exact limit 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 150 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?
The 150 KB search runs locally in your browser. Your image stays on your device the whole time.
Batch compress images to 150KB
Process a whole set of scans and photos down to 150 KB or less in one go. Free, private, batch ZIP, with no uploads anywhere.
Frequently asked questions
Is 150KB enough for a scanned document?
For photos and scans at screen resolution yes. Choose JPG for photos and WebP or PNG for text heavy documents to keep text sharp.
Should I resize before compressing to 150KB
Yes. Shrink to required pixels first, then compress to 150KB. You keep higher quality at the same byte size with less artifact.
Can I batch compress many images to 150KB without uploading
Yes. Add your folder, pick 150KB target, and compress together. Each image is searched locally for best quality under 150KB and you can download a ZIP.
