Convert AVIF images to JPG – locally in your browser
Why AVIF → JPG?
AVIF offers great compression but poor compatibility. Convert it instantly to the universal JPG format – locally in your browser.
Frequently Asked Questions
What is AVIF?
AVIF is a modern image format with excellent compression. It is not yet supported by all programs.
Are my images safe?
Yes, 100%. Conversion happens entirely in your browser.
Is there quality loss?
Both AVIF and JPG are lossy formats – minimal quality loss possible, barely visible in practice.
Is it free?
Yes, completely free. No sign-up, no limits.
About JPEG
JPEG (Joint Photographic Experts Group) was standardized as ISO 10918 in 1992 and remains the most widely used image format for photographs worldwide. Its lossy compression is based on the discrete cosine transform (DCT) and typically achieves compression ratios of 10:1 to 20:1 with barely perceptible quality loss. The algorithm was developed starting in 1986 by a working group led by Hiroshi Yasuda and quickly became the standard for web images, digital photography, and social media platforms. JPG files support 8-bit color channels in RGB color space and embedded EXIF metadata containing camera settings, GPS data, and timestamps. The format does not support transparency or animation and allows only one color space per image – limitations that are rarely relevant for its primary use as a photo format. With repeated compression, quality degrades progressively due to generation loss, making JPG unsuitable for editing and better suited as a final output format. The .jpg extension instead of .jpeg dates back to the 8.3 character limitation of early Windows file systems. JPEG XL was proposed as a successor in 2021 but has so far failed to gain meaningful market acceptance against WebP and AVIF.
About AVIF
AVIF (AV1 Image File Format) is based on the AV1 video codec from the Alliance for Open Media and was standardized in 2019. It offers the best compression of any current image format - typically 50 percent smaller than JPEG at the same quality - and supports HDR with PQ and HLG transfer functions, transparency, and animation. AVIF uses intra coding from the AV1 codec with block partitioning and filters optimized for still images. The format is supported by Chrome, Firefox, and Edge; Safari since version 16 (2022). AVIF is considered the most promising candidate for the next standard web image format. The disadvantage is the still longer encoding time compared to JPEG and WebP, which matters for large volumes of images. AVIF is patent-free and royalty-free, making it free from patent restrictions unlike HEIC/HEIF. AVIF with 10-bit color depth enables extended color gamut and higher dynamic range for professional photography.
Why convert AVIF → JPG?
AVIF (AV1 Image File Format) is the newest image format with the best compression of any current format — typically 50% smaller than JPG at equivalent quality. Despite excellent technical properties, AVIF still has limited support: older browsers (before Chrome 85, Firefox 93, Safari 16), numerous image editors, and most email clients can't display AVIF. Converting to JPG ensures compatibility on devices and platforms that can't natively display AVIF. This is especially important for email delivery and systems running older software.
