Compress an Image to 100KB

Many forms, job portals and government sites reject images larger than 100KB. Lowering the quality and dimensions a little is usually enough to slip under the limit while still looking sharp.

Everything runs locally in your browser — your images are never uploaded to a server, which is why it stays free, instant, and private.

How to compress an image to 100KB

1. Open the compressor and drop your image.
2. Lower the quality slider (and resize if needed) while watching the live file-size estimate.
3. Stop once the size is under 100KB, then download.

FAQ

How do I get an image exactly under 100KB?

Drop the slider and check the live size readout; reduce dimensions too if the photo is large. Stop as soon as it reads below 100KB.

Will compressing ruin the quality?

Moderate compression is usually invisible. The tool shows a preview so you can balance size and quality before downloading.

Is it free and private?

Yes — it's free with no signup, and compression runs in your browser so files are never uploaded.
