    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 JPEG images

    JPEG (JPG) is the most widely used image format for photographs and web images. It uses lossy compression to produce small file sizes while maintaining acceptable visual quality, making it ideal for photos shared online, via email, or on social media.

    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.

    JPEG — output format guide

    What is JPEG?

    JPEG (commonly saved with the .jpg extension) is a lossy raster image format designed for photographs and continuous-tone images. It compresses images by discarding visual data that the human eye is less likely to notice, producing small file sizes at the cost of some irreversible quality loss on each save.

    When was JPEG invented?

    JPEG was standardized in 1992 by the Joint Photographic Experts Group, building on research from the 1980s. It became the dominant format for digital photography and web images throughout the 1990s and remains the most widely used photo format today.

    What is JPEG used for?

    • Digital photography from cameras and smartphones
    • Web images, blog posts, and social media photos
    • Email attachments and document embedding
    • Print workflows where moderate compression is acceptable
    • Thumbnails and preview images

    Best practices for JPEG

    • Use quality settings between 75–90 for web photos — higher values rarely improve visible quality but increase file size significantly.
    • Avoid re-saving the same JPG multiple times; each save applies additional lossy compression.
    • Do not use JPG for images with text, logos, or sharp edges — PNG or WebP lossless are better choices.
    • Strip unnecessary EXIF metadata before publishing to reduce file size and protect location privacy.
    • Resize images to the display dimensions needed rather than uploading full-resolution photos.

    AVIF vs JPEG — format comparison

    AVIF usually produces smaller files than JPEG at the same visual quality, but JPG remains the safest choice for email and legacy software.

    When to choose JPEG over AVIF

    Converting AVIF to JPEG 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 JPEG

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

    • Start with the highest quality AVIF source file available — converting a low-quality image cannot restore lost detail.
    • Choose JPEG 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 JPEG file at full size before publishing or sharing to confirm quality meets your expectations.
