AVIF File

File extension	.AVIF
Category	Image File
Description	AVIF (AV1 Image File Format) is a relatively new image file format designed to offer high-quality compression and smaller file sizes compared to other popular formats like JPEG and PNG. It was developed by the Alliance for Open Media (AOMedia), a consortium of companies including Google, Mozilla, and Netflix. AVIF uses the AV1 video codec to compress image data, resulting in smaller file sizes while maintaining high image quality. This is achieved through advanced compression techniques such as intra-frame coding, chroma subsampling, and spatial prediction. AVIF also supports features like alpha channels, HDR (High Dynamic Range) images, and lossless compression. One of the main advantages of AVIF is its ability to offer high-quality images with smaller file sizes compared to other formats, which can improve web page loading times and reduce bandwidth usage. However, not all web browsers support AVIF natively, so it may not be the best option for all use cases. Overall, AVIF is an exciting new development in image compression technology, offering improved efficiency and flexibility for image file formats.

BMP File

File extension	.BMP, .RLE, .DIB
Category	Image File
Description	May be the simplest file format, BMP was developed jointly by Microsoft and IBM. That is why it is widespread on Windows platform. This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

Converted a batch of AVIF photos to BMP in seconds — perfect for my legacy imaging software that doesn't support AVIF. No quality loss at all.

Straightforward AVIF to BMP conversion, worked exactly as expected. Would be nice to have a bulk download option.

AVIF to BMP — Frequently Asked Questions ▼

What is an .avif file?

AVIF (AV1 Image File Format) is a still-image container built on the AV1 video codec. It produces files roughly 50% smaller than JPG at the same visual quality and supports 10- and 12-bit colour, HDR, and transparency.

Why convert AVIF to BMP?

Legacy Windows software, industrial control panels, medical imaging consoles, and old printer drivers cannot decode AVIF. BMP is the uncompressed Windows bitmap every such tool reads.

Will the BMP file be larger than the AVIF?

Yes — usually 20 to 60 times larger. AVIF uses AV1 compression; BMP stores raw pixel data. A 200 KB AVIF typically becomes a 6 MB BMP at Full HD resolution.

Is the conversion lossless?

The conversion to BMP is lossless from the decoded AVIF frame. Any compression loss already baked into the AVIF stays in the result; the converter does not add a second lossy step.

Does BMP support transparency from AVIF?

Only 32-bit BMP carries an alpha channel. The converter writes 32-bit BMP when the source AVIF has transparency, otherwise standard 24-bit BMP.

What is the file size limit?

The online converter accepts AVIF files up to 50 MB. For larger images or batch jobs, use the desktop Total Image Converter, which has no size limit.

Can I convert several AVIF files at once?

The online tool processes one file per upload. The desktop version converts entire folders in a single run and supports command-line automation through .bat scripts.

Convert AVIF to BMP — Modern AV1 Images for Legacy Windows Tools

AVIF is the AV1-based image format browsers adopted in 2020 — tiny files, sharp images, but rejected by older Windows software that still expects a plain bitmap. Converting AVIF to BMP unpacks the AV1 frame into raw pixel data that any Windows app from the last thirty years can open. Drop your .avif file above.

What Is AVIF?

AVIF (AV1 Image File Format) is a still-image container built on top of the AV1 video codec, standardised by the Alliance for Open Media in 2019. AVIF supports 10 and 12-bit colour, HDR, wide gamut, transparency, and animation, and produces files roughly 50% smaller than JPG at the same visual quality. Chrome, Firefox, Safari, and Edge all decode AVIF natively.

What Is BMP?

BMP (Windows Bitmap) is the raster format Microsoft introduced with Windows 3.0 in 1990. BMP stores pixel data uncompressed, row by row. It is bulky on disk but readable by every Windows imaging tool, every printer driver, and every legacy industrial or medical application — the kind of software that has not been updated since AVIF existed.

AVIF vs BMP — Format Comparison

Property	AVIF	BMP
Year	2019	1990
Developer	Alliance for Open Media	Microsoft
Compression	AV1 (lossy or lossless)	None (raw pixels)
File size (1920×1080)	~100-300 KB	~6 MB
Colour depth	Up to 12-bit	1, 4, 8, 16, 24, 32-bit
Transparency	Yes	32-bit BMP only
Legacy Windows tools	Rejected	Universal

When Do You Need AVIF to BMP Conversion?

Open an AVIF image in legacy Windows software that predates 2020
Use AVIF assets in industrial control panels or medical imaging consoles that only read BMP
Pass an AVIF photo into an old version of Paint, ACDSee, or IrfanView
Print AVIF images through an aged printer driver that cannot decode AV1
Embed an AVIF image as a desktop wallpaper, splash screen, or boot logo where BMP is required
Run pixel-level analysis in a tool that needs uncompressed input

Command-Line Conversion

Batch-convert an entire folder without opening the interface:

TotalImageConverter.exe C:\avif_files C:\bmp_out /ConvertTo bmp /ProcessRecursively

Add /ProcessRecursively to include subfolders. Save the command in a .bat file for scheduled or automated runs.
