FreeImageToolkitCompress Image to 100 KB
100 KB is the most common upload limit for documents, ID photos and listing images. Drop your photos here to get JPGs under 100 KB that still look sharp.
How to Compress an Image to 100 KB
- Drop one or more photos into the upload area above (JPG, PNG, WebP, GIF or BMP).
- The target is already set to 100 KB. Change it with the presets or type your own number.
- The tool finds the highest quality that fits. If the photo is still too large, it reduces the pixel dimensions slightly.
- Check the final size and dimensions in the list, then click Download. Several files are saved as one ZIP.
Good Quality at 100 KB
At 100 KB most photos keep around 800–1200 px width with no obvious compression artifacts. That is ideal for scanned documents, product photos on classified sites and attachments that must stay small.
For documents such as an ID card, a certificate or a utility bill, crop away the table or background first. Text stays sharper when the bytes go to the document itself. Need a PDF instead? Compress the images here, then combine them with Image to PDF.

Frequently Asked Questions
How do I compress an image to 100 KB?
Upload the image above. The target is preset to 100 KB, and the tool returns the highest-quality JPG that fits.
How do I reduce a scanned document to 100 KB?
Crop to the page edges, then compress it here. If text becomes hard to read, scan at a lower resolution first. A clean 1200 px wide page fits well under 100 KB.
Why is my result much smaller than 100 KB?
If the original JPG was already under 100 KB it is kept as is. Simple images with plain backgrounds can also fit at maximum quality with room to spare.
Can I choose WebP instead of JPG?
Yes, choose WebP in the output options. WebP gives better quality at the same size, but some forms only accept JPG.
Are my photos uploaded?
Yes. Everything runs in your browser. Your photos are never uploaded, which matters for ID photos, signatures and documents.
