FAQ
Got questions?
AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media (AOMedia) and published in its 1.0 specification in February 2019. It is based on the AV1 video codec and offers significantly better compression than JPEG, PNG, and WebP, with support for transparency, high dynamic range (HDR), wide color gamut, and 12-bit depth. However, despite Chrome supporting AVIF since version 85 (August 2020) and Firefox since version 93 (October 2021), many email platforms, forums, corporate messaging clients, and legacy services still do not support AVIF. GIF, created by CompuServe in June 1987, remains the universally compatible format for animated images.
This is GIF's most important limitation: its palette is restricted to 256 colors per frame (GIF89a specification, defined by CompuServe in 1989). AVIF can represent millions of colors with depth up to 12 bits per channel. During conversion, a color quantization algorithm (typically Median Cut or Wu) is applied to select the 256 most representative colors, and remaining colors are approximated through dithering. The result can have visible color banding in smooth gradients or photographs, which are the images most affected by the palette limitation. For images with few flat colors, such as illustrations, icons, or logos, the difference is imperceptible.
AVIF supports animated image sequences stored in the ISOBMFF container (ISO Base Media File Format, ISO/IEC 14496-12), the same container used by HEIC and MP4. Animated AVIF sequences can be converted to animated GIF, preserving individual frames and inter-frame timing. The main limitation is that GIF supports a maximum of 256 colors per frame, so videos or animations with many colors will suffer visible degradation. For complex animations, consider converting to animated WebP instead of GIF, since WebP does not have the 256-color limitation.
Despite being over 37 years old, GIF maintains an irreplaceable presence in several contexts: it is the only animated image format that works in all email clients (Gmail, Outlook, Apple Mail, Yahoo Mail) without special support; Tenor and GIPHY, the world's most used GIF platforms, distribute content primarily in GIF format; many forums and communities (Reddit, Discord with directly embedded images) display animated GIFs natively; and numerous legacy content management systems only accept JPEG, PNG, and GIF. The cultural convention of calling any short animated image a 'GIF' also maintains demand for the format.
GIFs are significantly larger than AVIFs. AVIF leverages the AV1 codec to achieve compression up to 10 times better than JPEG for equivalent images. GIF has no temporal compression between frames (except through frame differencing in some implementations) and its per-frame compression uses LZW (Lempel-Ziv-Welch), a lossless algorithm from the 1980s that is much less efficient than modern codecs. A 100 KB AVIF can generate a 2-5 MB GIF for the same visual content. For long animations, the size difference can be 10x-50x.
Yes. The conversion uses native browser APIs (Canvas API for image decoding and manipulation, along with JavaScript libraries for color quantization and GIF encoding). AVIF support in the browser requires Chrome 85+, Firefox 93+, Edge 121+, or Safari 16+. In older browsers or corporate environments with outdated browser versions, AVIF decoding may not be available. Your image never leaves your device: all processing happens locally.
Convert AVIF to GIF: email compatibility, forums, and platforms without AVIF support
AVIF (AV1 Image File Format) is the most modern image format with significant browser support. It was developed by the Alliance for Open Media (AOMedia), a consortium founded in 2015 by Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix, and its 1.0 specification was published in February 2019. AVIF is based on the AV1 video codec, which is the successor to VP9 and the open-source competitor to HEVC/H.265. AVIF compression outperforms JPEG by 50% or more at equivalent quality, surpasses WebP by 20-30%, and the format supports advanced features that JPEG cannot: alpha transparency (like PNG and WebP), high dynamic range (HDR10 and HLG), wide color gamut (Display P3, Rec. 2020), color depth up to 12 bits per channel, and EXIF and ICC profile metadata. Chrome has supported AVIF since version 85 (released in August 2020), Firefox since version 93 (October 2021), Safari since version 16 (September 2022), and Edge since version 121 (January 2024).
GIF (Graphics Interchange Format) was created by CompuServe engineer Bob Berry and his team in June 1987 (version GIF87a), with a significant update in July 1989 (GIF89a) that introduced support for animations, basic transparency (1-bit, one color can be transparent), and application extensions. Despite its severe technical limitations — palette restricted to 256 colors, lossless LZW compression that is inefficient for photographs, no audio support — GIF has remained the de facto format for short animated images on the internet for nearly four decades. The reason is its universal compatibility: GIF works in all email clients (including Outlook in all its versions, which notoriously has poor support for modern HTML), in all web browsers without exception, on virtually all forum and social media platforms, and on any operating system from DOS to Windows 11 and macOS Sequoia. Tenor (owned by Google since 2022) and GIPHY (owned by Shutterstock since 2023) distribute billions of GIFs monthly, and Tenor's integration in the Google keyboard and in applications like WhatsApp, Slack, and Teams has maintained the cultural relevance of the format.
The need to convert AVIF to GIF typically arises in two distinct scenarios. The first is backward compatibility: a user downloads or generates an image in AVIF (because it is the highest-quality, lowest-weight format available) and needs to share it in a context that does not support AVIF. Corporate email clients, especially Outlook in Windows environments with Microsoft 365, do not support AVIF and have limited or inconsistent support even for WebP in HTML emails. If the image you want to include in an email is an animation or requires maximum compatibility, GIF remains the only truly universal option. The second scenario is creating content for communication platforms: many teams using Slack, Microsoft Teams, or Discord generate visual content in modern formats (AVIF, WebP) and need to convert it to GIF so that it displays as an embedded animated image in chat rather than as an attachment. Convertir.ai performs the AVIF to GIF conversion entirely in the browser: it decodes the AVIF using native browser APIs, applies optimized color quantization for GIF's 256-color palette, and encodes the resulting GIF in JavaScript, without uploading any data to external servers.
