This tool searches for a JPEG encoder quality that aims to produce an output at or below the requested target size. Best-effort.
Notes
- JPEG Only: This algorithm only functions on JPEG outputs.
- Best-Effort Search: The tool searches for a JPEG encoder quality that aims to produce an output at or below the requested size where possible.
- Bounded Iterations: The quality search is strictly bounded to prevent infinite loops. It does not guarantee an exact byte count.
- Unachievable Targets: If the minimum possible JPEG quality still exceeds your target size, the algorithm will safely return the smallest possible output it generated.
- Local Processing: Search occurs entirely in your local browser.
