100 KB is the most common upload ceiling — job portals, visa applications, CMS avatars and email-friendly images. Most photos reach it at good visual quality without shrinking dimensions.
Getting the best result at 100 KB
- A 800–1000 px photo usually fits under 100 KB at 70–85% quality — visually near-identical to the original.
- Visa and immigration portals often pair a 100 KB (or 240 KB) cap with a square pixel size — resize to the required square first.
- WebP squeezes ~30% more quality into the same 100 KB if the destination accepts it.
Frequently asked questions
How does the tool get my image under 100 KB?
The tool binary-searches the JPG/WebP quality at your image's dimensions, and if even the lowest quality is too big it steps the dimensions down until the file fits under the target.
Can I compress a photo for a visa application to 100 KB?
Yes — and if you're making the photo itself, Ohata's passport photo maker crops to your country's official spec first, then compress the export here.
Is my image uploaded anywhere?
No. Compression runs entirely in your browser — your image is processed on your own device and never uploaded to a server.
