Frequently Asked Questions
Image format comparisons.
When should I use PNG over WebP or JPEG?
Use PNG when you require absolute lossless quality, pixel-perfect detail, or alpha-transparency layers (such as logos and icons). Use WebP or JPEG for standard photographic assets to save storage space.
How does the quality slider affect outputs?
For lossy formats (JPEG and lossy WebP), the quality slider controls how aggressively compression algorithms discard high-frequency color detail. A setting between 75% to 85% typically offers the best balance of file size reduction and visual clarity.
