Compress image to 100 KB
Application documents, ID scans and photos for forms that allow up to 100 KB.
How to compress a photo to 100 KB
- Set the size. It is already set to 100 KB. You can change it above.
- Add your photo. Drag it in, choose it, or paste a screenshot. You can add several at once.
- Download. Each result shows its final size, quality and dimensions.
At 100 KB a photo or scanned page stays sharp and readable, which suits ID cards, certificates and clear portraits.
Tips for the best result
- Crop first. Cutting away background leaves more of the size limit for your face or document. Use the Image Cropper or the Passport Photo Maker.
- Need exact pixels too? Some forms ask for both, such as 200 × 230 px under 50 KB. Resize with the Image Resizer, then compress here.
- Got an iPhone HEIC photo? Convert it with HEIC to JPG first.

Frequently asked questions
How do I compress an image to 100 KB?
Add your photo, and it is reduced to under 100 KB automatically. Then download it. The tool tries the highest quality that fits before it makes the picture smaller.
Will the photo still look good?
The tool keeps as much quality as the size allows. It first lowers JPG quality, and only reduces the width and height when that is not enough. You can see the final quality and dimensions before you download.
Is my photo uploaded anywhere?
No. Everything happens in your browser on your own device. Your photo is never sent to a server, so it is safe for ID photos and documents.
What format is the result?
A JPG file, because almost every online form accepts JPG. Transparent areas are filled with white.
The form says "KB" but my file is slightly over. Why?
Some sites count 1 KB as 1,000 bytes and others as 1,024. The tool aims a little under the limit, measured in 1,000-byte KB, so the file passes either way.
