Cutting-Edge Format

AVIF represents the latest in image compression technology — dramatically smaller than PNG with virtually no visible quality difference.

Transparency Preserved

Unlike JPG, AVIF keeps full alpha channel data from your PNG. Get both transparency and superior compression in one format.

Speed Matters

Smaller AVIF images mean faster page loads and reduced bandwidth costs — a measurable performance gain for any website.

About formats

PNG (Portable Network Graphics) is a lossless raster image format developed by the PNG Development Group and published as a W3C Recommendation on October 1, 1996, created as a patent-free replacement for GIF after the Unisys LZW patent controversy. PNG uses a two-stage compression pipeline: a prediction filter selects the optimal per-row preprocessing (none, sub, up, average, or Paeth), then DEFLATE compression encodes the filtered data. The format supports rich color modes — 1/2/4/8/16-bit grayscale, 8/16-bit per channel true color, and indexed color with palettes up to 256 entries — all with optional alpha transparency ranging from a single transparent color to a full per-pixel alpha channel with 256 or 65536 levels. PNG also stores gamma correction, ICC color profiles, text metadata, and suggested background color. One advantage is lossless compression with transparency — PNG preserves every pixel exactly while supporting smooth semi-transparent edges, making it the standard format for web graphics, UI elements, logos, screenshots, and any image where artifacts or color shifts are unacceptable. Universal support is another core strength: every web browser, operating system, image editor, and programming library handles PNG natively. The format has proven remarkably durable — after nearly three decades, PNG remains the default lossless web image format. While newer formats like WebP and AVIF offer better compression, PNG's combination of lossless quality, full transparency, and absolute ubiquity keeps it indispensable.
Initial release: October 1, 1996
AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

Why convert PNG to AVIF?

AVIF offers the best compression available today — files can be 50% smaller than PNG while maintaining near-identical visual quality and transparency.

Does AVIF support transparency?

Yes — AVIF fully supports alpha channels. Transparent PNG images retain their transparency after conversion to AVIF format.

Which browsers display AVIF?

Chrome, Firefox, Edge, Opera, and Safari (from version 16) all render AVIF images natively. Coverage continues to grow rapidly.

Is PNG to AVIF free?

Basic conversion is free on Convertio. Premium accounts unlock batch processing and priority encoding speed.

How does AVIF compare to WEBP?

AVIF generally achieves better compression than WEBP at the same quality level, especially for photographic content and complex gradients.

Is AVIF lossless or lossy?

AVIF supports both modes. Lossless AVIF preserves every pixel from your PNG; lossy AVIF delivers dramatic file size reduction.
