Can I set a target file size?
Yes. CODAC makes bounded encoding attempts and reports whether the target was reached. It does not guarantee a target that the selected format and image cannot achieve.

Frequently asked questions
Useful details before you process your files.
Will compression reduce image quality?
Lossy JPEG and WebP output can reduce detail. PNG output is lossless but browser re-encoding may not make every PNG smaller. Preview and compare before downloading.
Are transparent areas preserved?
Transparency is preserved when the output format supports it, such as PNG or WebP. JPEG requires a solid background.
