AVIF (AV1 Image File Format) is a modern, highly-compressed image format that offers excellent quality at small file sizes. Converting to BMP (Bitmap) format provides uncompressed, pixel-perfect images with universal compatibility across nearly all software and operating systems. While BMP files are larger, they offer simplified editing, guaranteed compatibility with legacy systems, and raw pixel data that's ideal for professional editing workflows.
BMP has been around since 1990 and is widely supported across all operating systems, devices, and software applications, unlike AVIF which has limited support in older systems.
BMP's uncompressed format makes it easier to edit in many image editing applications, preserving every pixel without compression artifacts that can occur in AVIF.
BMP provides a raw, uncompressed representation of your image data, perfect for archiving AVIF images without any quality loss or compression artifacts.
Click the upload area or drag and drop your AVIF images directly onto the converter. Our tool accepts single or multiple files up to 100MB each.
Our converter instantly begins transforming your AVIF images to BMP format using advanced algorithms that preserve all original image data and quality.
Once conversion is complete, download your BMP files individually or as a ZIP archive. All conversions happen locally in your browser for maximum privacy.

Convert AVIF to BMP when working with older software or systems that don't support the newer AVIF format but can process standard BMP files.
BMP's uncompressed nature makes it ideal for professional image editing when you need to preserve every detail from your original AVIF images.
Convert AVIF to BMP for design projects requiring raw image data that can be easily manipulated in pixel-based graphic design applications.
Use BMP format for long-term archival of AVIF images when you need a format that will remain readable regardless of future codec support challenges.
Consider file size requirements before converting
BMP files can be 10-20 times larger than AVIF files. If you plan to convert many images, ensure you have sufficient storage space. For web use, consider PNG as a more size-efficient alternative that still offers transparency.
Verify software compatibility before converting
If you're converting AVIF to BMP for use in specific software, check which BMP version it supports. Some applications only work with older BMP versions (BMP v3) that lack alpha channel support and other advanced features.
Use compression tools after conversion if needed
If file size is a concern, consider using a lossless compression tool on your BMP files after conversion. Tools like 7-Zip can compress BMP files efficiently without quality loss when you need to store or transfer them.
Save the converted BMP in 32-bit mode for transparency
Our converter preserves transparency by default, producing 32-bit RGBA BMP files (BMP v5). If your software doesn't recognize the transparency, consider converting to PNG format instead for better transparency support.
Optimize your BMP settings for specific use cases
For maximum compatibility with older systems, consider using 24-bit RGB BMP format without alpha channels. For image editing and high-quality work, 32-bit RGBA is the better choice despite the larger file size.
No, you won't lose quality. BMP is an uncompressed format that preserves all pixel data from your original AVIF image. In fact, converting to BMP eliminates any compression artifacts that might be present in the AVIF source. However, be aware that BMP files will be significantly larger than their AVIF counterparts due to the lack of compression.
AVIF uses advanced compression technology that can reduce file sizes by up to 50% compared to formats like JPEG, while BMP stores uncompressed raw pixel data. As a result, BMP files are typically 10-20 times larger than equivalent AVIF files. This size difference is the trade-off for BMP's universal compatibility and lossless quality.
Yes, but with limitations. Since BMP doesn't support animation, our converter will extract the first frame of an animated AVIF file and convert it to a static BMP image. If you need to preserve animation, consider converting to GIF or WebP format instead.
This depends on the BMP version. Our converter produces BMP version 5 files, which support alpha channel transparency. However, some older applications might only support earlier BMP versions without transparency. For maximum transparency compatibility, we recommend using PNG format.
Our converter creates 32-bit RGBA BMP files by default, which offers the highest color fidelity and supports alpha channel transparency. If your AVIF image doesn't use transparency, the converter will still use 32-bit to preserve maximum color information. You can adjust color depth settings after downloading if needed for specific applications.
Our converter handles AVIF files up to 100MB each. Since AVIF is a highly compressed format, this allows for conversion of very high-resolution images. Keep in mind that the resulting BMP files will be significantly larger, so ensure you have sufficient storage space available before converting large or numerous images.
BMP is preferable when working with legacy software that may not fully support PNG, or for applications that require uncompressed pixel data like certain scientific or medical imaging software. BMP also has a simpler data structure that makes it easier to process programmatically. For web use or general purpose storage, PNG typically offers better compression with similar quality.
You can convert BMP files back to AVIF format, but it's important to understand that once an image is converted from AVIF to BMP, any compression benefits of the original AVIF are lost. Converting back to AVIF will create a new compression instance, not restore the original file. If you need to preserve the original AVIF's characteristics, we recommend keeping backups of your original files.
