About this free bulk image compressor
Portals across India and Pakistan reject photos that cross their KB limits — 100KB is the most common ceiling for documents, signatures and ID photos. Most free compressors cap you at 20 files a day or lock batch downloads behind a subscription. This one doesn't: drop unlimited JPG, PNG or WebP photos and each is tuned to your exact target size. The engine binary-searches the JPEG quality setting (and shrinks dimensions only as a last resort) until every output lands at or just under your target, so visual quality stays as high as possible — text on PAN cards and documents remains crisp. Everything is computed locally with the Canvas API: no server, no queue, no account, no watermark. It works offline once the page is loaded and never stores or transmits your images.
Frequently asked questions
How do I compress an image to 100KB?
Upload your photo(s), keep the 100KB preset and click Compress Images. The tool tunes quality and dimensions until each file is 100KB or slightly under, then gives you the downloads.
Can I compress multiple images at once?
Yes — drop as many photos as you like. Each is compressed to your target size, and you can download them one by one or all together as a single ZIP file.
Will my photo look bad at 100KB?
Quality is reduced only as much as needed to hit the size. For document photos, ID cards and signatures the result stays sharp and readable.
Is there a daily limit?
No. Files never leave your device, so there's nothing to meter — compress as many images as you want, as often as you want.
