Three steps. Nothing to learn.
- Choose one JPG, PNG, WebP, BMP, HEIC, or HEIF image.
- Keep the 240KB target or enter another limit.
- Inspect the comparison and risk, then download.

What “best” means here
We search multiple JPEG quality and resolution candidates within a 60-second budget. The result is the strongest candidate found under your limit—not a promise of lossless compression or global mathematical optimality.
Read the compression methodology →Questions, answered plainly.
Does my image get uploaded?
No. Decoding, resizing, encoding, and comparison happen in your browser. The image is not sent to our server.
Will the result always be accepted?
The downloaded JPG is kept below your chosen byte limit. A third-party website may also check dimensions, composition, naming, or other rules, so acceptance cannot be guaranteed.
Why is the result slightly below 240KB?
The encoder uses 99% of the stated limit as its internal ceiling, reducing rejection caused by rounding or upload-system overhead.
