Image Compressor Online – Compress to Custom KB

Q: What's the difference between Quality and Target KB mode?

Quality mode lets you adjust compression strength for general use. Target KB mode compresses toward a chosen file size such as 20KB, 50KB, 100KB, 200KB, or a custom value from 5KB to 500KB.

Q: Can I use a custom KB size like 35KB or 75KB?

Yes. Enter any target value from 5KB to 500KB in the target size field and compress the image.

Reduce file size by quality or choose 20KB, 50KB, 100KB, 200KB, or any custom target from 5KB to 500KB.
