Compress an Image to Exactly 100 KB

Many Indian portals - university admissions, government job recruitment, Kerala PSC (KPSC Thulasi), and entrance exam forms - reject any photo larger than 100 KB. Compressly compresses your image to exactly 100 KB without a noticeable quality drop, entirely inside your browser, so the photo never gets uploaded to any server before you choose to submit it.

This method works perfectly for:

• Kerala PSC (KPSC Thulasi) photo uploads

• Passport photo and ID card uploads
• Civil Service exam documents
• University admission portals
• 10th, 12th, degree, PG entrance exam forms
• Private job application portals

Tips to get perfect 100 KB results

• Use JPG or WebP for the smallest file size.
• If your form requires a specific size (for example 150 x 200 px), resize your photo before uploading.
• If your image is slightly above 100 KB, reduce the target to 95 KB.

Frequently asked questions

Will my photo be exactly 100 KB?
Compressly re-encodes at different quality levels until the result lands at or under 100 KB - usually within a few KB of the target, not the exact byte count, since encoders can't guarantee that precisely.

Does compressing to 100 KB ruin photo quality?
Not noticeably for most photos. 100 KB gives JPEG enough room to keep faces and text sharp - it's the low-effort formats like large PNGs that lose the most when squeezed down this far.

Is my photo uploaded anywhere?
No. Compression runs locally in your browser using HTML5 Canvas. Your image never leaves your device unless you choose to submit it yourself.
