Where a 100 KB limit shows up
Online job applications, university and exam portals, and customer-profile uploads often cap photos at 100 KB. The limit exists to keep their storage and page loads small.
How it gets a picture under 100 KB
The tool encodes your picture again and again, searching for the highest quality that still fits inside 100 KB. That keeps it as sharp as possible.
If even a low quality is still too big, because the picture has a huge number of pixels, it is also scaled down a little and the search repeats. The result note tells you which quality was used and whether the picture was resized.
Getting the best 100 KB result
Start from the original, not a copy that was already compressed. Every extra round of compression loses detail.
For a portrait, 100 KB is comfortable at around 600 pixels wide. If the picture is much larger, resize it first; the tool will otherwise have to reduce quality more than necessary.
Frequently asked questions
Are my photos uploaded to your server?
No. The conversion runs entirely inside your browser using your own device. Your files are never sent to us or to any third party, which is why it also works for private photos and large batches. Once the page has finished loading you can even switch off your internet connection and the tool keeps working.
How many pixels can a 100 KB photo have?
A typical portrait photo at good quality fits in about 100 KB at roughly 600 × 800 pixels. Simpler pictures can be larger.
What if my picture ends up larger than the limit?
That only happens with extremely detailed or very small pictures that cannot be compressed far enough. The tool then tells you the smallest size it could reach, and you can resize the picture first with the Resize Image tool.
