PNG to AVIF Converter

Squeeze PNGs down with the most efficient web image codec available — AVIF lossy can be up to 90% smaller than PNG while keeping full transparency and wide-gamut colour. Converts in your browser.

For modern web delivery, AVIF is currently the best-in-class image format — and converting your PNG files to AVIF can cut bandwidth by up to 50% versus JPG with no visible quality loss. You will most often encounter PNG files as screenshots from Windows, macOS, Linux, iOS, and Android, logos, icons, and UI mockups exported from Figma, Sketch, Illustrator, or Photoshop, graphics with transparency that need to overlay on other content, and AVIF is the obvious destination when your goal is high-traffic websites. Converter.Plus runs the whole PNG→AVIF conversion locally in your browser — there is no upload, no signup, no watermark, and no per-file size cap. Drop a single file or a whole batch and grab the results as individual downloads or a single ZIP.

Portable Network Graphics (PNG) was standardized by the W3C in 1996. PNG was designed as a free, lossless replacement for the patent-encumbered GIF. It stores every pixel exactly, supports a full alpha channel for transparency, and remains the default lossless format in design tools, browsers, screenshots, and operating system UIs. You will most often encounter PNG files as screenshots from Windows, macOS, Linux, iOS, and Android, logos, icons, and UI mockups exported from Figma, Sketch, Illustrator, or Photoshop, graphics with transparency that need to overlay on other content.
