What to expect
100 KB is a comfortable budget for a 1,000–1,200 px wide web photo in JPEG, and WebP or AVIF can often keep more width at the same size.
Questions
How do I compress a photo to 100 KB?
Add the image above; the target is already set to 100 KB. The tool finds the highest JPEG quality that fits under 102400 bytes, shrinking the width only if needed, then you save the file.
Why is my image under 100 KB but smaller than expected?
The search steps in quality increments and always stays under the limit, so the result is usually a little below the target. That leaves margin for forms that count KB as 1,000 bytes.
My form also requires exact pixel dimensions. What do I do?
Enter the required width and height as max width and max height before adding the image. The tool resizes first and then fits the size target, which gives better quality than letting it shrink on its own.
Is my photo uploaded?
No. The compression runs in your browser with WebAssembly; the file stays on your device. That matters for ID photos and signatures.
