Image processing
Keep size when you can; trade quality vs weight.
JPEG/WebP use quality; PNG is mostly lossless—photos often convert better to WebP.
Target KB searches quality steps; only then reduces dimensions.
Pixels scale with width×height; 82% on both sides ≈ 67% pixels.
FAQ
Compress image to a target KB · FAQ
Is there a limit on how many images I can compress?
No limits. Unlike cloud compressors that cap you at 10 or 20 files, everything runs directly in your browser with zero paywalls.
Are images uploaded?
Never. Re-encoding is handled entirely on your device via Canvas. No files ever leave your machine.
Why compress to an exact KB target?
Government portals, job applications, and exam registries often enforce strict 100KB/200KB caps. Our tool hits that threshold automatically.
Why is PNG hard to shrink?
Lossless PNG has no JPEG-like quality slider; try WebP or JPEG for photographs.
Will it look soft?
Lossy modes balance sharpness against target size. Preview the output before downloading.
