What 100 KB is enough for
In 100 KB a photo stays clear at a size fit for most forms and web pages. Many application forms ask for photos of up to 100 KB, so this is one of the most common limits.
| Limit | Bytes |
|---|---|
| 100 KB, counted as 1000 bytes per KB | 100,000 bytes |
| 100 KB, counted as 1024 bytes per KB | 102,400 bytes |
| This tool keeps the file under | 100,000 bytes |
Check the pixels the form asks for
Some forms set both a file size and dimensions in pixels. Crop or resize the photo to the dimensions first, then compress it here: the size in KB is the last step.
Quality first, then pixels
A JPG or WebP file gets smaller in two ways: a lower quality, which drops fine detail the eye hardly sees, or fewer pixels. The tool lowers the quality first, only as far as the photo still looks good, and then makes the photo smaller. Tick “Keep the dimensions” when the size in pixels must stay; then only the quality goes down.
When the photo itself is the problem
Compression makes a photo lighter, not better: it cannot fix a blurry, dark or badly framed picture. If the photo is for a CV, a profile or an application and you have no good one, a professional headshot made from a few selfies gives you one.
