PrismNookCompress image to 100 KB
Upload forms often reject photos over 100 KB. Drop your image here and get a version under 100 KB at the best quality that fits. If needed we reduce the dimensions slightly, and we tell you when we do.
Private by design: everything happens in your browser. Nothing is uploaded.
How to compress an image to 100 KB
- Choose your photo or drop it onto the box. You can add several at once.
- The target is already set to 100 KB. We search for the highest quality that fits under it.
- Check the result: the new size and dimensions appear under each image.
- Click Download, or download everything as a ZIP.
What fits in 100 KB?
For a typical photo saved as JPG at good quality, 100 KB fits roughly 1200 × 800 px. Simple images with plain backgrounds fit more; detailed, noisy photos fit less. 100 KB is a common limit for job applications, profile photos, marketplace listings and email attachments.
100 KB keeps a typical photo looking good on any phone or laptop screen. If your form also asks for exact pixel dimensions, resize first with the image resizer, then compress.
Other sizes
Need a different limit? Use the image compressor and type any size in KB, or pick 20 KB, 50 KB, 200 KB.
Frequently asked questions
How do I reduce a photo to 100 KB without losing quality?
Some quality loss is unavoidable, but you can minimise it. Crop away anything you don't need first, and choose JPG for photos. We pick the highest quality that still fits under 100 KB.
Why was my image made smaller in pixels?
When even low quality settings can't reach 100 KB, the only other option is fewer pixels. For a typical photo, 100 KB fits roughly 1200 × 800 px. We always show the final dimensions.
What if the form needs both a size and exact dimensions?
Resize to the required width and height with our image resizer first, then compress here. Doing it in that order gives the best quality.
Are my images uploaded?
No. Conversion happens in your browser on your own device, so your images never reach our servers.
