Format Details
AVIF
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec developed by the Alliance for Open Media. It delivers superior compression efficiency compared to JPEG and PNG, often reducing file sizes by 50% or more while maintaining excellent visual quality. AVIF supports HDR, wide color gamut, and transparency, making it an ideal choice for the modern web.
imageBMP
BMP (Bitmap) is one of the oldest raster image formats, developed by Microsoft for the Windows operating system. It stores pixel data in an uncompressed or minimally compressed form, resulting in large file sizes but perfect lossless quality. BMP is widely supported across Windows applications and is commonly used as an intermediate format in image processing workflows.
imageConverting AVIF to BMP: what actually changes
AVIF to BMP is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .AVIF and .BMP each hold
.AVIF is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .BMP is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .BMP encodes pixels, dimensions and colour depth — not what the file is about.
Quality and file size
.AVIF has already discarded detail during compression, and converting to .BMP cannot bring it back. The output will be lossless from here on, so the file gets larger without recovering what the original threw away.
When this conversion is the right one
Reach for .BMP when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .BMP to .AVIF using the same tool.
Tips for a clean AVIF to BMP conversion
Start from the original file
Convert the .AVIF you started with, not an earlier .BMP output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/avif becomes image/bmp. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .AVIF has a transparent background or animation, confirm .BMP supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
