Compress Image to 100KB Online — Free, Fast & Browser-Based

A 100 KB image cap is a deliberate compromise. It is small enough that portals can store and display millions of uploads cheaply, but generous enough to keep a face photo or a clear document scan looking acceptable.

You will hit this limit everywhere — competitive exam portals (UPSC, SSC, banking, railways), visa appointment systems, university admission forms, corporate HR onboarding, and many e-government services for utility connections, vehicle registration, and tax filings.

The 100 KB budget is large enough that smart JPEG quality reduction alone is usually sufficient. The tool runs a quality search: it starts at high quality (around 90), checks the output size, and steps down until the file lands under 100 KB.

For PNG photographs, the compressor switches output format to JPG, which is dramatically more efficient for natural images and almost always required to hit 100 KB.

For PNGs that contain text or screenshots, the compressor preserves PNG format but applies palette quantisation and image optimisation passes to bring the file under the limit while keeping the text crisp.

For passport-style photographs, crop the image tightly to your face before compressing. Background pixels still cost bytes even if they do not matter for the result.

For scanned documents, prefer grayscale or black-and-white over full colour if the portal allows. The file is dramatically smaller and the text remains perfectly readable.

For screenshots of forms or text, leave the output in PNG and rely on palette quantisation. Converting to JPG often makes the text fuzzy because of JPEG's smoothing.

Identity photos, signed signature cards, and document scans are all things you should be cautious about uploading. iLoveeIMG handles compression entirely in the browser using local JavaScript and WebAssembly libraries.

Your image is never uploaded, never logged, and not visible to anyone outside your own browser. Closing the tab discards everything from memory.
