How to compress an image to 100 KB
1. Choose the image
Pick the photo, ID card or certificate scan you need to upload. JPG, PNG and WebP work.
2. Wait for the 100 KB copy
Compression starts by itself and aims for a file under 100 KB. No size to choose.
3. Check and upload
The smaller image downloads on its own. Open it once to check it is still clear, then upload it.
FAQ
Which forms need an image under 100 KB?
Many exam, visa, scholarship and government portals cap a photo or ID scan at 100 KB.
How does it reach 100 KB?
It lowers the JPG quality first and then makes the picture smaller in pixels until the file fits. A PNG is saved as a JPG when that is the only way to fit.
Will the picture still be clear?
A face or signature stays readable at this size. Fine detail in a large photo is lost, which is where the size is saved.
Is my photo uploaded?
No. The image is compressed inside your browser, so photos, signatures and ID scans never leave your device.
The form also asks for a width and height. Can I set them?
Crop or resize the picture in the Photo editor first, then bring it here to reach the file size.
Is it free?
Yes. There are no ads, no watermark and no daily limit.
