Everything About Image Format Conversion
Different image formats have different characteristics, making it important to choose the optimal format for your use case. PNG is a lossless format with transparency support, ideal for logos and icons. JPG uses lossy compression optimized for photos with smaller file sizes. WebP, developed by Google, offers high compression efficiency that can replace both PNG and JPG.
This tool supports free conversion between PNG, JPG, and WebP, plus DNG (Digital Negative) RAW files. Convert DSLR or smartphone RAW captures to web-ready formats. The quality slider adjusts JPG/WebP compression levels to balance quality and file size.
All conversions happen locally via the browser's Canvas API. Images are never sent to any server, ensuring safe processing of personal or confidential photos. File size comparison before and after conversion shows exactly how much space was saved (or added).
Pro tip: For website performance optimization, prioritize WebP format — it provides 25-35% smaller files than JPG at equivalent quality. Use PNG or WebP when transparency is needed; converting to JPG fills transparent areas with white. DNG conversion extracts the embedded preview, so full-resolution RAW data may differ.
