Compress Image to 100 KB
Compress photos to a strict 100 KB ceiling — for tiny avatars, thumbnails, and lean forms.
Your images stay on your device. Nothing is uploaded.
100 KB is aggressive: at standard viewing sizes most photos still look fine, but high-detail images may show visible quality reduction. The defaults below are tuned for 100 KB — drag the slider for finer control.
All processing happens on your device. Drop a photo to compress.

Frequently asked questions
- How do I compress an image to 100 KB?
- Upload your image and the default settings on this page are pre-tuned to land you around 100 KB. Use the quality slider to nudge the file size up or down — the result preview shows the exact byte count before you download.
- Will the image still look good at 100 KB?
- For most photos, yes. The pre-tuned quality and max-dimension settings prioritise visual quality while landing close to 100 KB. Very small targets (under 100 KB) on detailed images may need a visible quality reduction.
- Which format gives the best result for 100 KB?
- WebP usually produces the smallest file at a given quality, then JPEG, then PNG. The format selector lets you switch; the default reflects the best balance for 100 KB.
- Can I compress to exactly 100 KB?
- Browser compression is quality-driven, not byte-driven, so the resulting file size is close to — but not exactly — 100 KB. Staying under a target is what email clients, forms, and platforms enforce, so a slightly smaller file is always safe.
- Can I batch compress multiple images to 100 KB each?
- Yes — use the bulk compressor. Drop a folder of images and each one is processed with the same settings, then downloaded as a ZIP.
