AVIF to BMP for Image Workflows
Fast, instant AVIF to BMP conversion. No signup required. Just drop your .avif file and get .bmp in seconds.
Batch Settings
Transparency will be lost
AVIF supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
HDR data will be tone-mapped
Your AVIF file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Animation frames will be lost
AVIF supports animation, but BMP does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your AVIF file may contain EXIF, XMP, ICC metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your AVIF file uses a wide color gamut (sRGB, Display P3, BT.2020 wide gamut). BMP uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
在日常的数字生活中，我们常常会遇到各种图片格式，而每种格式都有它独特的应用场景。AVIF作为一种新兴的图像格式，以其出色的压缩效率和高质量表现，在网络传输和存储方面显示出巨大潜力。然而，在某些特定情境下，例如需要无损编辑、兼容老旧系统或进行位图级别的像素操作时，传统的BMP格式则更受青睐。将AVIF转换为BMP，不仅仅是格式上的简单切换，更是为了满足您在不同工作流和设备间的兼容性需求。无论您是设计师、开发者，还是普通用户，了解并掌握这种转换方法，都能让您的图片处理更加得心应手，确保图像在不同平台和应用中都能以最佳状态呈现。

在大陆及台湾地区，部分专业软件或特定显示设备对AVIF的支持度仍有待提高，此时转换为BMP能更好地保证兼容性和稳定性。
About AVIF to BMP Conversion
Whether you're one of the many photographers, designers, and content creators who work with AVIF files daily, there comes a time when you need BMP instead. AVIF is the newest image format based on AV1 video codec, delivering exceptional compression — up to 50% smaller than JPEG at the same quality.
Here's a typical scenario: you receive a .avif file but your project, platform, or client requires .bmp. BMP is an uncompressed raster format that preserves every pixel but produces very large files. Rather than searching for desktop software or wrestling with command-line tools, you can convert AVIF to BMP online in seconds with CocoConvert.
This conversion is ideal when you Your AVIF file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts BMP uploads. The conversion helps you improve file compatibility across devices.
AVIF supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead. Common misconception: ""My file's transparent background will carry over to BMP"" — in reality, bmp doesn't support transparency. transparent areas become solid (usually white). save as png or webp if you need transparency.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.
How to Convert AVIF to BMP
- 1
Drop your file
Drag your .avif file onto the converter. Need to process many files? Add up to 5 at once (100 for Pro).
- 2
Set output to BMP
Pick BMP from the format list. The converter automatically tunes settings for the AVIF→BMP pair.
- 3
Hit Convert
Processing happens server-side — your browser stays responsive. Most image files convert in under 10 seconds.
- 4
Download and use
Your .bmp file is ready to plug into your workflow. Download it or share the link (expires in 24 hours).
What Happens When You Convert AVIF to BMP
Your AVIF image is decoded into raw pixel data, then re-encoded as BMP.
Your AVIF file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Transparency is resolved: transparent pixels are composited onto a white background
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Should You Convert AVIF to BMP?
When to Convert
- ✓Your AVIF file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts BMP uploads
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You need to preserve transparent areas — BMP doesn't support transparency
- ✗You want to preserve HDR information — BMP only supports standard dynamic range

Common Mistakes When Converting AVIF to BMP
"My file's transparent background will carry over to BMP"
BMP doesn't support transparency. Transparent areas become solid (usually white). Save as PNG or WebP if you need transparency.
"BMP will be smaller than my AVIF file"
BMP uses no compression, so the output file is often larger than a lossy AVIF. If you need a small file, BMP may not be the right choice.
"My animated AVIF will stay animated after conversion"
BMP does not support animation. Only a single frame will be saved. Use WebP or GIF to preserve animation.
Frequently Asked Questions
Who needs to convert AVIF to BMP?
This conversion is commonly used by photographers, designers, and content creators. Typical reasons include improve file compatibility across devices and ensuring compatibility with downstream tools or platforms.
Can I convert AVIF to BMP without losing quality?
AVIF supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Do I need to install software to convert AVIF to BMP?
No. CocoConvert runs entirely in your browser — no downloads, no plugins. It works on macOS, Windows, Linux, iOS, and Android.
How many AVIF files can I convert at once?
Free users can convert up to 5 files per hour. Pro subscribers get 100 files per hour with larger size limits (5 GB per file). Business API users can integrate batch conversion directly into their tools.
Is there an API for AVIF to BMP conversion?
Yes. CocoConvert offers a Business API for automated conversions. It supports all the same format pairs available in the web interface, including AVIF to BMP.
