JPM is a JPEG 2000-based image format used for storing raster graphics with advanced compression and image quality features. AVIF is a modern image format based on the AV1 codec, designed for very high compression efficiency while preserving excellent visual quality.
Why convert jpm to avif
Converting JPM to AVIF can significantly reduce file size while keeping strong image quality. AVIF is widely used for web delivery, storage optimization, and modern image workflows because it often compresses better than older formats.
Best software for conversion
The best choice depends on whether you need batch conversion, command-line control, or a simple interface. For most users, XnConvert is one of the easiest and most reliable options for converting JPM images to AVIF. It supports many formats and offers batch processing.
For advanced users, ImageMagick can also be used, especially when paired with AVIF support in the system build. If you need a dedicated online converter, choose one that explicitly supports both JPM input and AVIF output, since not all web tools handle JPM files.

Using XnConvert:
- Open the program and add your JPM file.
