When you need an image under 100 KB
At 100 KB an image loads fast on any connection and works well for email signatures, blog posts, social media uploads, and website thumbnails. Most photos from a phone are 3-8 MB. This tool brings them under 100 KB without visible quality loss.
Tips for best results
At 100 KB you have enough room for a sharp photo at web resolution. The compressor uses SSIM-based quality probing to find the sweet spot. For landscape or product photos, you will barely notice the difference from the original. If you need multiple images under 100 KB, drop them all at once and compress in bulk.
Need more control?
The full compressor has custom targets, aggression control, format switching, and before/after comparison.
FAQ
Is compressing to 100 KB free?
Yes. No watermark, no file limit, no sign-up. Compress as many images as you want.
Will my image look blurry at 100 KB?
The compressor uses SSIM-based quality probing to find the highest quality that fits within 100 KB. For most photos the difference from the original is invisible. If the result looks too soft, try a slightly higher target or switch to WebP format which compresses more efficiently.
What formats can I compress?
JPG, PNG, WebP, AVIF, and animated GIF. The tool automatically picks the best compression strategy for each format.
Does this upload my image to a server?
No. The compression engine runs entirely in your browser. Your image never leaves your device.
Can I compress multiple images at once?
Yes. Drop multiple files and they all get compressed to the target size. Download each result individually or all at once as a zip.
