Why this compressor
Exact size, private and free
Most compressors only offer "low, medium, high" and leave you guessing. Here you pick the size in KB — and it fits.
🎯 Always under 100 KB
The best quality that fits under 100 KB — photos stay sharp and text stays readable.
📄 Readable documents
Scans of ID cards, marksheets and certificates get a white background and darker text, so they stay clear when compressed.
♾️ Batch + ZIP
Compress up to 100 images at once and download them in one ZIP. Free, no sign-up.
When you need images under 100 KB
100 KB is a common limit for scanned documents on application portals — ID proof, marksheets, caste or income certificates — and a handy size for email attachments, websites and WhatsApp status images.
At 100 KB a photo can stay around 1200–1800 pixels wide, so it still looks sharp on phones and laptops. The tool lowers the JPG quality first and only reduces the dimensions when a very big photo still doesn't fit, then raises the quality again as high as 100 KB allows.
For scans, tick "Signature or document: make the paper background white" — grey or yellow paper turns white and the text gets darker, which also helps the file fit. Tighter limit? Try compress to 50KB or 20KB.
