How do I compress an image to 100KB?

Add your image and the tool lowers quality just enough to land at or under 100 KB, then you download it. For most photos the result still looks sharp on screen and in documents.

Will 100KB lose noticeable quality?

Some quality is traded for the smaller file, but at 100 KB most everyday photos still look clean on screen. The tool keeps as much detail as it can at your target.

Are my images uploaded anywhere?

No. Every image is processed on your own device in the browser and never leaves it, so your files stay private.

Compress an image below 100KB

100 KB is the most common target: light enough for fast web pages, forum and profile avatars, government and exam forms, and email — while still looking clean. Add your photo and it's compressed to land at or under 100 KB, keeping as much detail as that size allows. It runs entirely in your browser, so nothing is uploaded.

What to expect at 100 KB

100 KB is enough for a photo roughly 1000 to 1200 pixels wide to look clean on a screen. Skin tones, skies and other smooth areas hold up well; heavy texture is where you would first notice the trade. For a scanned document or an ID photo, 100 KB is generous — those compress far better than a photograph because most of the frame is a flat background.

Which format to choose

For photographs, JPG is the safe choice, and WebP is usually 25–35% smaller again at the same visible quality — worth picking if whatever you are uploading to accepts it, as a few older forms still don't. For screenshots, charts, logos and anything containing text, PNG keeps edges crisp where JPG smears them into a grey haze; the file will be larger, so give it a more generous target. If your image needs a transparent background, use PNG or WebP — JPG has no transparency and will flatten it onto white.
