How to use this tool
How it works
- Choose JPEG, PNG, or WebP files. Type is read from bytes.
- Set a target size. The tool searches encoder quality until the cap is met or reports TARGET_UNMET.
- Download a new file. A candidate that misses the target is still a real encode, not a renamed original.
Files stay in this tab. No upload.
Lossless PNG may miss a tiny target. Originals are not overwritten.
Supported inputs and outputs
JPEG, PNG, WebP. AVIF is gated.
Example
A PNG under a 200 KB cap encodes to a file at or below 200000 bytes.
Questions and answers
What if the target is impossible?
