Reduce an image to 100 KB
100 KB is a comfortable limit for most portrait photos and scanned documents, and it is a common cap for email attachments, web forms and profile pictures. This page starts with Target file size → 100 KB. Choose your picture and the tool picks the highest quality that fits, so you don't need to drag a quality slider and guess.
PNG screenshots and logos are converted to JPG for this mode, because PNG files cannot be squeezed to a target size. Transparent areas turn white rather than black.
Ways to get better quality at 100 KB
- Start from the original photo instead of a screenshot of it; screenshots add noise that costs bytes.
- Set an exact width, such as 1000 px, if the destination does not need the full camera resolution. Fewer pixels leave more room per pixel.
- Keep the minimum field empty unless the form requires one.
A 100 KB limit in the wild
The verified NEET UG signature upload allows 10–100 KB, and the NEET photo allows 10–200 KB. Their rules and source links are on the NEET page.
Frequently asked questions
How do I reduce a PNG to 100 KB?
Choose the PNG, keep the output as JPG, and the tool compresses it to the limit. PNG itself is lossless and cannot be shrunk to a target size without converting.
Why can a photo be 5 MB but my result is only 90 KB?
A phone photo has millions of pixels. To fit 100 KB the tool lowers the pixel count and the JPEG quality, which is fine for screens and forms but not for large prints.
Does this reduce the dimensions of my image?
Only when needed. If the original already fits at high quality the dimensions stay the same; otherwise they are reduced just enough to meet the limit.
Can I compress several images at once?
Not yet. Process them one at a time; the tool resets quickly between photos.
