How to compress an image to 100KB
- Drop your photos in the box above.
- Max file size is already set to 100 KB and the format to JPG. Leave the width and height as they are, or make them smaller for better quality.
- Click Resize images and save the result. Each file shows its new size.
Job portals, exam and government forms, and email often cap uploads at 100KB. The tool tries a high quality first and steps down until the file fits under 100 KB.
If a big photo still can't get under the limit, lower the width (say to 1200 or 800 px). Fewer pixels compress much better than lower quality.
Compress image to 100KB: questions
How do I reduce a photo to under 100KB?
Drop it here, keep the format on JPG with the 100 KB limit, and click Resize. If it says it couldn't reach the size, also make the width smaller.
Does compressing reduce quality?
A little, since JPG compression throws away detail you mostly can't see. Shrinking the pixel size first keeps it looking sharper.
Can I compress a PNG?
Yes. It's saved as JPG (or pick WebP), because PNG is lossless and can't be squeezed to a target size.
