How to convert FLV to AVIF?
You can convert FLV to AVIF with MConverter in three easy steps:
Choose FLV files from your device
At the top of this page, drag and drop your FLVs. You can also click to select FLV files using your operating system's file picker. Another method is to press the keyboard shortcut Ctrl+V (⌘+V on Mac) to paste an FLV file you have copied to clipboard. Converting a folder with FLV 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. On desktop platforms, you can download the AVIF files to a different folder by clicking on SAVE TO... You may see a share icon as well. Use it to directly share the AVIFs with other apps.
About the formats
Video file formats
Macromedia, now Adobe
FLV is a Flash video file. It was created for online streaming of video content using the Adobe Flash Player. However, since Flash reached end-of-life in 2020, the video format is now only used by Adobe Animate and playable by some third party apps like VLC.
Image file formats
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 will support AVIF in iOS 16 (coming Fall 2022).
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.
MConverter also lets you create AVIF animations from video or GIF, up to 5 minutes long. Note that AVIF animations are currently only playable in Chrome and not Firefox.
