    About AVIF images

    AVIF (AV1 Image File Format) is a modern image format that delivers excellent compression and quality. It is ideal for web photos when you need smaller files than JPEG or WebP with broad browser support.

    About GIF images

    GIF (Graphics Interchange Format) supports simple graphics and short animations with a 256-color palette. Convert static GIFs to PNG or WebP for smaller files, or export to JPG for photographic content.

    AVIF — source format guide

    What is AVIF?

    AVIF is a modern raster image format based on the AV1 codec. It typically delivers smaller files than JPEG or WebP at similar visual quality, supports HDR, wide color gamuts, and transparency, and is supported in all major browsers.

    When was AVIF invented?

    AVIF was finalized in 2019 as part of the AV1 video codec ecosystem developed by the Alliance for Open Media. It brings AV1 compression to still images and is increasingly adopted for modern web delivery.

    What is AVIF used for?

    • High-efficiency web images and responsive picture elements
    • Photography where bandwidth and storage matter
    • Replacing large JPEG or PNG assets on performance-focused sites
    • Next-generation image delivery alongside WebP fallbacks

    Best practices for AVIF

    • Use AVIF for web photos when you can provide JPG or PNG fallbacks for older clients.
    • Keep quality between 50–80 for photos; very high settings rarely justify the extra bytes.
    • Test output on target browsers before replacing all site assets with AVIF.
    • Prefer AVIF over JPEG when optimizing Core Web Vitals and Largest Contentful Paint.

    GIF — output format guide

    What is GIF?

    GIF is a raster format limited to 256 colors per frame with optional animation support. It remains popular for short looping animations, simple icons, and memes, though static GIFs are often larger than PNG or WebP equivalents.

    When was GIF invented?

    GIF was introduced by CompuServe in 1987. It became the early web standard for simple graphics and short animations before newer formats like PNG and WebP gained adoption.

    What is GIF used for?

    • Short looping animations on social media and messaging apps
    • Simple graphics with flat colors and limited palettes
    • Legacy web graphics and emoji-style animations
    • Converting static GIFs to more efficient modern formats

    Best practices for GIF

    • Convert static GIFs to PNG or WebP to reduce file size.
    • Use GIF only when you need broad compatibility for simple animations.
    • Keep palettes small when creating GIFs to control file size.
    • For web animations, test WebP or video formats before defaulting to GIF.

    When to choose GIF over AVIF

    Converting AVIF to GIF is useful when you need to optimize images for a specific platform or use case. Whether you are preparing photos for a website, reducing file sizes for faster loading, or switching to a format with different features like transparency or better compression, ConvertPort handles the conversion instantly while preserving as much quality as possible.

    Best practices for converting AVIF to GIF

    Follow these guidelines to get the best results when converting AVIF images to GIF:

    • Start with the highest quality AVIF source file available — converting a low-quality image cannot restore lost detail.
    • Choose GIF when it fits your use case: JPG for photos and small file sizes, PNG for transparency and sharp graphics, WebP for modern web optimization.
    • Resize images to the dimensions you actually need before or during conversion to avoid unnecessarily large output files.
    • Review the converted GIF file at full size before publishing or sharing to confirm quality meets your expectations.
