Why ToFormat?
Lossless, Uncompressed
BMP stores image data without compression. Converting AVIF to BMP gives you exact pixel data — perfect for applications that require raw bitmaps.
Universal Compatibility
BMP is one of the oldest and most widely supported formats. Runs on every OS, embedded device, and software since the 1990s.
Simple Editing
Many legacy and specialized editors work best with BMP. Convert AVIF to BMP for direct manipulation without format headaches.
About the Formats
🚀 What is AVIF?
AVIF (AV1 Image File Format) is a next‑generation format based on the AV1 video codec. Created by the Alliance for Open Media, it offers up to 50% better compression than JPG, supports HDR, wide color gamut, and transparency. AVIF is great for modern websites but not always compatible with older software.
All AVIF conversion tools →🖼️ What is BMP?
BMP (Bitmap) is a raster graphics format developed by Microsoft. It stores pixel data uncompressed (usually), resulting in large files but exact fidelity. It's the simplest format, supported everywhere.

Upload AVIF
Drag and drop your AVIF files. You can upload up to 20 at once.
Choose BMP options
Select bit depth (24-bit for photos, 8-bit for paletted graphics). Default is 24-bit true color.
Download BMP
Your BMP files are ready. Download individually or as ZIP. Files auto-delete in 10 minutes.
When to Convert AVIF to BMP
💻 Legacy Software
Old programs, embedded systems, or custom hardware often require BMP. Convert AVIF to BMP to ensure compatibility.
💡 For modern apps: try BMP to AVIF →🎨 Pixel Art & Editing
Pixel artists and some editors prefer BMP for its simplicity and exact pixel control. No compression artifacts.
💡 Vector alternative: AVIF to SVG →🔧 Reverse Engineering
BMP is easy to parse. If you're analyzing image data or writing low-level code, BMP is the safest intermediate.
💡 Raw format: AVIF to DNG →📂 Archiving Simple Graphics
For icons, logos, or UI elements where file size doesn't matter, BMP offers a future-proof, simple format.
💡 Lossless alternative: AVIF to PNG →Format Comparison
| Format | AVIF | BMP |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Yes | No |
| File Size | Smaller | Larger |
BMP files are huge — often 10-20x larger than AVIF. Only use when necessary. For general use, AVIF to PNG offers lossless compression with smaller size, or AVIF to JPG for even smaller files.
💡 Pro Tips
- BMP supports different bit depths: 1, 4, 8, 16, 24, 32-bit. Choose 24-bit for photos, 8-bit for simple graphics (smaller).
- If your AVIF has transparency, use 32-bit BMP with alpha channel (not all software reads it).
- BMP can store color profiles (ICCP) — we preserve them if present in your AVIF.
- For maximum compatibility with very old systems, use 24-bit BMP (no compression, no alpha).
- Converting animated AVIF to BMP will produce only the first frame. For animations, use AVIF to GIF.
- BMP is uncompressed by default, but there is RLE compression (rarely used). We offer uncompressed for reliability.
- We strip metadata by default for privacy, but you can keep EXIF by toggling the option before conversion (rare in BMP).
How AVIF to BMP Conversion Works
AVIF uses advanced compression based on the AV1 codec, while BMP is a simple format that stores raw pixel data. When you convert AVIF to BMP, our servers fully decode the AVIF image to raw pixels (preserving all detail and alpha if present), then write a BMP header and the pixel data with your chosen bit depth.
The process is lossless — the pixel values are preserved exactly. If your AVIF was lossy, the artifacts are already in the pixels; BMP stores them as-is. For animated AVIF, only the first frame is converted (BMP does not support animation).
Files are processed in memory and permanently deleted after 10 minutes.
AVIF vs BMP: When to Use Each
AVIF is for modern web delivery: small size, HDR, transparency. BMP is for compatibility and simplicity: huge files, but works everywhere.
Think of BMP as the "lowest common denominator" — if a system can display images at all, it can display BMP. That's why it's still used in embedded devices, bootloaders, and legacy apps.
BMP Variants and Compatibility
Over the years, many BMP variants appeared: OS/2 BMP, Windows BMP with different compression. Our converter outputs standard Windows BMP (BITMAPINFOHEADER) with uncompressed data, which is compatible with virtually all software.
