AVIF to BMP Converter

Summary

Upload an AVIF image and download it instantly as a BMP file — all processing happens locally in your browser.

How it works

1. Click "Choose AVIF File" and select your .avif image from your device.
2. The browser decodes the AVIF using the built-in image decoder.
3. The decoded image is drawn onto an HTML5 Canvas element.
4. Canvas exports the pixel data as a BMP file via a Blob URL.
5. Click "Download BMP" to save the converted file to your device.

Use cases

• Convert AVIF photos from a modern camera or web download to widely-compatible BMP.
• Prepare images for legacy software that does not support AVIF.
• Extract raw pixel data from AVIF files without installing desktop software.
• Batch-test AVIF rendering support in different browsers.
• Convert AVIF screenshots for use in Windows-native applications.
• Preserve image quality before applying further edits in BMP-native editors.
