Convert AVIF to BMP
Free online AVIF to BMP converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert AVIF to BMP?
AVIF is one of the newest, most efficient image formats available. BMP is one of the oldest, with zero compression. This pairing exists only for equipment that predates compressed image formats entirely, for example a decades-old scientific instrument or embedded display. Expect a dramatic size increase when a small AVIF gets decoded back out to raw, uncompressed pixels.
Tips
- Files will be large. Prefer PNG unless the destination software specifically requires .bmp.
- Processing happens entirely in your browser; the AVIF is never uploaded.
From a new format to an old one
AVIF, based on the AV1 video codec, uses advanced image compression. BMP sits at the other end: no compression at all, every pixel written out as a raw color value, in a format that predates the web. Converting between the two is a real jump. Expect the BMP to be many times the size of the source AVIF, since you're unpacking a highly compressed file into a container designed with no compression in mind.
Frequently asked questions
How do I convert AVIF to BMP?
Drop your AVIF file into the converter above, adjust the quality if needed, and click "Convert to BMP". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the AVIF to BMP conversion lossless?
Yes. BMP is a lossless format. The conversion preserves all visual information from the source file.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my AVIF files uploaded to your servers?
No. All AVIF to BMP conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
