Compress and review
Check dimensions, quality and actual bytes before downloading.
Prepare a screenshot with labels
Start with the relevant portion of the screen. At 100 KB, zoom in on labels and check the final width against the form’s minimum. If the tool cannot meet the cap or the JPG blurs text, trim unused screen area in the source or use a permitted larger budget.
In an Edge test, a synthetic 900 × 1200 PNG (3.31 MB) was exported as a JPEG using this preset’s automatic quality and size settings. The download was 96.02 KB at 765 × 1020 px. Check that any small labels remain legible after resizing.

Compress Image to 100KB questions
Short answers, then the practical details.
How does the 100 KB image target work?
The tool tests actual JPEG output bytes against 100 × 1024 bytes, adjusting quality and then dimensions when needed. It keeps the best quality found within the current dimensions and target. Review the result before submitting because a strict file-size limit can require visible loss of detail.
Will compressing an image to 100 KB change its dimensions?
Dimensions may decrease when JPEG quality alone cannot fit your 100 KB limit. The result displays the output width and height so you can compare them with a form’s minimum requirements. If the photo becomes too small or soft, choose a larger target or a less detailed source image.
Can I keep transparency in a 100 KB image?
This preset exports JPG, which does not support transparency, so transparent source areas become white. It accepts JPG, PNG and WebP inputs, but the downloaded format is JPEG. Use the general image compressor with PNG output if retaining alpha transparency matters more than the 100 KB target.
