What if my image is very small already?

If the image already fits under your target, it is still re-encoded cleanly and returned — you always get a file that satisfies the limit.

Which formats can I input?

JPG, PNG, and WebP inputs are supported everywhere. The output is re-encoded to your chosen format, with JPEG as the safe default for upload portals.

Compress Any Photo to an Exact KB Limit — In Your Browser

Government portals, passport submissions, and university applications often demand photos under a strict size — commonly 100KB, sometimes 20KB or 50KB. Instead of guessing quality settings, this tool runs an iterative binary search over the encoder quality (and, when needed, gently downscales dimensions) until the output is guaranteed to fit under your limit.

The default target is 100KB, but the size box accepts any value in KB, so the same tool covers 20KB signature uploads and 500KB email attachments alike. Everything runs locally — your documents never leave your device.

Frequently Asked Questions

Everything you need to know about using Compress Image to 100KB (or Any Size) safely and efficiently.

The tool iteratively tunes the JPEG/WebP quality parameter, and falls back to proportional downscaling only when quality alone cannot reach the target, until the resulting file is guaranteed to be at or under your KB limit.
