Frequently Asked Questions
If the original is already highly optimized, re-compression may not reduce size further. Our tool returns the original with a warning rather than giving you a larger file.
For web use, 70–80% quality reduces file size by 50–80% with virtually no visible quality loss. For photography, 85–95% is recommended.
JPEG, PNG, and WebP for both input and output. You can cross-convert between formats — compress a PNG and output as WebP for significantly smaller files.
JPEG and WebP use lossy compression. At quality settings of 75% and above, the difference is typically imperceptible to the human eye. PNG is always lossless.
