AVIF → PNG
Convert AVIF images to PNG – locally in your browser
Why AVIF → PNG?
AVIF images are compressed but not universally compatible. PNG is lossless and universal – convert directly in your browser.
Frequently Asked Questions
Why convert AVIF to PNG?
PNG is lossless and universally supported. Ideal for converting AVIF without quality loss.
Are my images safe?
Yes, conversion happens entirely in your browser.
Is it free?
Yes, completely free without sign-up.
About PNG
PNG (Portable Network Graphics) was released in 1996 as an open standard and developed as a patent-free alternative to GIF after Unisys demanded licensing fees for the LZW algorithm used in GIF in 1994. PNG uses lossless compression based on the Deflate algorithm and supports up to 16 bits per channel as well as full-color transparency through a dedicated alpha channel. The format is particularly suited for graphics with sharp edges, text, logos, and screenshots – anywhere JPEG would produce artifacts through its lossy compression. PNG does not support animation; this gap is filled by the unofficial APNG format, which is supported by most browsers. The interlaced variant (Adam7) enables progressive loading where a coarse preview becomes visible even with minimal data transferred. PNG is the de facto standard for lossless web graphics and is supported by all browsers, operating systems, and image editing programs. For photography, however, PNG is inefficient since file sizes are significantly larger compared to JPEG or WebP, which is why PNG is primarily used for graphics and screenshots.
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 → PNG?
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 PNG ensures compatibility on devices and platforms that can't natively display AVIF. This is especially important for email delivery and systems running older software.
