How to convert BMP to AVIF?
You can convert BMP to AVIF with MConverter in three easy steps:
Choose BMP files from your device
At the top of this page, drag and drop your BMPs. You can also click to select BMP files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste a BMP file you have copied to clipboard. Converting a folder with BMP files to AVIF is also supported: simply paste or drag and drop it.
Click or tap on AVIF from the list of target formats
Alternatively, you can use the search field to quickly find the format you need, whether it's AVIF or something else.
Download your AVIF files, after MConverter has finished processing them
There's an option to automatically download the converted AVIF files, so you don't have to press the download icon for each AVIF. You may see a share icon as well. Use it to directly share the AVIFs with other apps.
About the formats
Image/Picture file formats
BMP files, also known as bitmap image files, are uncompressed raster images. They contain a file header with a bitmap identifier, width, height and color settings among other information, as well as bitmap pixels with different colors. Because of the lack of any compression, BMP files often have a relatively large file size. Therefore, it may be beneficial to convert such images to newer, better-optimized formats like WebP and AVIF.

AOMedia (Alliance for Open Media)
The AV1 Image File Format (AVIF) is a new format which promises better compression and smaller file sizes than JPEG, PNG, WebP, and all other current image formats on the web. Based on the generic HEIF image format, AVIF supports alpha transparency, HDR, lossy and lossless compression. AVIF is already being used by Netflix and Microsoft.
Support in Google Chrome and Chromium-based browsers (like Microsoft Edge and Opera) has landed in late August 2020. Firefox can display AVIF images from version 93, released in October 2021. Meanwhile, Apple's Safari still does not support AVIF.
MConverter's AVIF encoder uses a Constant Rate Factor (CRF) of 10, so that there is no noticeable reduction in image quality while keeping the file size as small as possible.
Common questions about converting BMP to AVIF
Can I convert BMP to AVIF in bulk?
Yes, MConverter supports batch converting of multiple BMPs to AVIFs simultaneously. You can even drag and drop folders containing BMPs to convert to AVIF. Pasting BMP files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a BMP file to AVIF, if its size is 1 GB?
Yes, with MConverter Premium you can convert big BMPs, up to 1 gigabyte each. The free version lets you convert files up to 200 MB. If you need to convert BMP files over 200 megabytes, try MConverter Premium.
Is converting BMPs to AVIF safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your BMP files are only accessible by you. 24 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your BMPs and other converted files immediately after finishing the conversion by clicking the bin icon. Join others who have trusted us to convert over 2,645,920 files so far.
How long does it take to convert BMP to AVIF?
For most images, the wait should be less than a minute. If they are animated, it may take a little longer. However, MConverter also supports converting larger images, meaning that it could take a while (up to over an hour, for example).
