FAQ
Will JPG to PNG improve quality?
No, converting to PNG preserves current quality but cannot restore lost data from JPG compression.
What is SVG embed mode?
Embed mode wraps the JPG image inside an SVG container. The image remains bitmap but can be used in SVG contexts.
Which format is best for web?
WebP offers the best compression while maintaining quality. Use PNG if you need transparency.
