FAQ
Q: Does converting JPG to PNG improve quality?
A: No. JPG’s lossy compression is irreversible. Converting to PNG prevents further quality loss during editing, but cannot restore lost detail.

A: WebP is ideal for modern websites - excellent compression with quality. JPG for photos where transparency isn’t needed. PNG for graphics and logos.
Q: Will conversion affect image quality?
A: Depends on format. Lossless formats (PNG to PNG) preserve quality. Converting to lossy formats (PNG to JPG) reduces quality slightly. Converting from lossy to lossless (JPG to PNG) doesn’t recover lost quality.
Q: Can I batch convert multiple images?
