AVIF → BMP

Learn about the formats: What is BMP? What is AVIF?

Convert AVIF raster images into uncompressed BMP format instantly using our online tool. This conversion is ideal for compatibility with legacy software that does not support modern codecs.

AVIF is a modern, highly compressed raster image format designed for the web, utilizing advanced compression algorithms to keep file sizes extremely small. BMP, on the other hand, is a traditional uncompressed raster format that stores pixel data directly without compression. When you convert an AVIF file to BMP, the image data is uncompressed into a raw bitmap structure, making the resulting file significantly larger in size.

Because AVIF is a lossy format by nature, any data discarded during its initial compression is permanently gone. Converting it to the lossless BMP format will preserve the current pixels exactly as they are, but it cannot restore the detail that was already lost in the original AVIF file.

Tips

Ensure your hard drive has enough free space, as BMP files are uncompressed and much larger than AVIF.
Use this conversion only when specific desktop software or hardware demands raw BMP input.
Check image dimensions before converting to avoid unexpectedly massive file outputs.

Common use cases

Opening modern AVIF web graphics in older raster-based image editors that only accept BMP.
Integrating web-downloaded AVIF assets into legacy desktop publishing workflows.
Preparing raw raster data for low-level image processing scripts that require uncompressed bitmaps.
