Image Compressor
Reduce a photo to the exact file size you need.
Processed privately on your device
Helpful guidance
Many university, scholarship and government portals limit photo size because thousands of applications must be stored and reviewed quickly. A ‘40 KB’ rule usually means the uploaded file must contain no more than 40,000 bytes. This compressor uses that safer decimal interpretation and checks the finished file itself instead of guessing from dimensions or quality.
Start with the requested target and leave the advanced settings closed. The tool first searches for the best practical JPEG or WebP quality, then reduces dimensions only when quality alone is not enough. A slightly smaller, sharper image normally looks better than a large image with severe compression blocks. Always inspect faces and printed text before submitting.
JPG is the safest choice for ordinary camera photos and application portraits. WebP often creates a smaller file but some older portals reject it. PNG is best for logos, screenshots and transparency, but photographic PNG files can be difficult to shrink. Processing through canvas also removes EXIF details such as GPS position, device model and capture time.
Frequently asked questions
Why does my portal ask for 40 KB?
Small files reduce storage and make forms usable on slow connections. The exact rule belongs to the portal, so use its stated number and confirm the downloaded Blob is at or below it.
Will compression make my photo blurry?
Some quality loss is unavoidable at very small targets. The tool protects quality first and clearly reports when dimensions had to be reduced, so you can choose a slightly larger target if print clarity matters.
Should I choose JPG, PNG or WebP?
Choose JPG for photos and maximum portal compatibility, PNG for graphics or transparency, and WebP only when the receiving site explicitly accepts it.
Is my original photo uploaded?
No. Decoding, resizing and encoding happen inside your browser. Only the finished file is offered back as a local download.
