About Image Format Conversion
Different image formats trade off quality, transparency support, and file size. PNG is lossless and supports transparency — ideal for graphics and screenshots. JPG uses lossy compression and no transparency — best for photos. WebP and AVIF are modern formats offering smaller files at similar quality, with AVIF generally producing the smallest files. BMP is an uncompressed legacy format still required by some older software.
This tool draws your image onto an HTML canvas and re-encodes it in the target format — no data ever leaves your device.
