How to compress an image to 100 KB

Updated 24 October 2026 · about 1 minutes

Many forms ask for photos under 100 KB or 200 KB. The Image Compressor can aim for an exact size and keeps the quality as high as possible.

Step by step

1
Open the Image Compressor
Choose your photo.
2
Choose "Target file size"
Under "Compress by" pick Target file size, then 100 KB (or 50 KB, 200 KB, 500 KB, or a custom number).
3
Pick JPG or WebP
JPG works everywhere; WebP gets better quality at the same size.
4
Compress and download
Press Compress image. If even low quality is too big, the picture is made slightly smaller to fit.

For ID and exam forms, check whether they also require exact pixel dimensions; use the Image Resizer for that.

Usually not: most phone photos look good at 100 KB once scaled to about 1200–1600 pixels.
