Resize Image to 100KB

Get your image under 100 KB instantly

Many government portals, university exam forms and job application sites refuse photos larger than 100 KB. Doing this by hand is frustrating — you guess a quality value, export, check the size, and repeat. ImgWus removes the guesswork.

• Upload your JPG, PNG or WebP photo.
• The target is pre-set to 100 KB.
• The app binary-searches quality to land just under the limit while keeping the image as sharp as possible.
• Download a file that is guaranteed to be under 100 KB.

Why a 100 KB limit is so common

A 100 KB cap keeps server storage manageable when millions of applicants upload documents. The limit usually applies to passport-style photos and signatures, where a small file is perfectly adequate. The trick is hitting that size without making the photo unreadable — which is exactly what target-size compression is built for.

If your photo is still slightly soft at 100 KB, try resizing the dimensions down first (for example to 600×800) and then compressing; smaller dimensions reach the target at a much higher quality.

Works for any size target

Although this page is tuned to 100 KB, you can change the target to 50 KB, 200 KB, 1 MB or any value your form requires. The same intelligent search applies, so you always get the best image that fits.
