BMP to AVIF Converter

About AVIF

AVIF (AV1 Image File Format) is the most compression-efficient image format widely available today. Developed by the Alliance for Open Media (AOM) — a consortium that includes Google, Mozilla, Apple, Netflix, and others — and released in 2019, AVIF uses the AV1 video codec to achieve image file sizes 40–60% smaller than equivalent JPGs, and typically 20–30% smaller than WEBP, at the same visual quality. It supports 10-bit color depth, HDR (high dynamic range), wide color gamuts (P3, Rec. 2020), and transparency.

Browser support has grown rapidly: Chrome added AVIF support in version 85 (2020), Firefox in version 93 (2021), and Safari in version 16 (October 2022). Edge supports AVIF. Google Search already uses AVIF for image thumbnails, and Google Photos converts uploads to AVIF internally. For websites, smaller image files mean faster page loads, better Core Web Vitals scores (Largest Contentful Paint in particular), and reduced bandwidth costs for both the server and the visitor.

When to use AVIF: For any web-published image where load speed matters — hero images, product photos, blog thumbnails, portfolio images. The smaller file sizes have a measurable impact on page speed scores and, by extension, SEO ranking signals. If your target audience is on modern browsers (Chrome, Firefox, Safari 16+), AVIF is the strongest compression choice available without sacrificing quality.

When to stay with JPG or PNG: When maximum compatibility is required — enterprise environments running Internet Explorer, older Android WebView apps, desktop image-editing software that has not yet added AVIF support, or email clients. For these use cases, JPG remains the safer universal choice.
