ImgLab tool
Compress Image Online
Compress images to smaller file sizes or target sizes like 100KB, 200KB, 500KB and 1MB.
Use case
Reduce file size for the destination, not for its own sake
A smaller file is useful only when it still looks right where it will be viewed.
Start with the target size or automatic mode, then inspect the areas of the image that matter before downloading.
- Start with the destination requirement.
- Keep the original file when it matters.
- Review the finished output before submitting or publishing it.

FAQ
Can every image become 100KB?
Most can be made smaller, but detailed photos may need smaller dimensions or visible quality tradeoffs.
Is WEBP always smaller?
WEBP is often efficient, but some upload forms only accept JPG or PNG.
Why does compression make text blurry?
Text and sharp edges show artifacts sooner than normal photo areas. Resize first and avoid excessive compression.
Should I use target size or automatic mode?
Use automatic mode for general sharing. Use target size when a form lists a hard maximum.
