Why convert PNG to AVIF — the smallest web format for graphics and logos
Convert PNG to AVIF to achieve the maximum compression for web graphics without sacrificing quality or transparency. PNG files are large: lossless compression preserves every pixel but produces heavy files that increase page load times. AVIF delivers significantly smaller output than PNG — for graphic content, AVIF typically outperforms WebP lossless, producing files smaller than any other widely-supported web format. Converting png to avif without losing quality is achievable because AVIF supports lossless compression that preserves pixel-perfect output while achieving better compression than PNG or WebP.
For websites with logos, icons and UI graphics, switching to AVIF for website delivery reduces image weight to the absolute minimum. A PNG logo at 100 KB might compress to 60–70 KB as AVIF — meaningfully smaller than the ~74 KB WebP lossless equivalent. Across an entire website with dozens of graphic assets, the cumulative page weight reduction from PNG to AVIF conversion is substantial. Google PageSpeed Insights recommends serving images in next-gen formats, and AVIF represents the current state of the art for web image compression.
AVIF supports alpha transparency — this is critical for logos, icons and graphics that rely on transparent backgrounds. Converting a PNG with transparency to AVIF preserves every transparent pixel exactly. The AVIF output is visually identical to the source PNG on any background color. There is no need to flatten transparency or add a background when converting PNG to AVIF for web use.
Browser support for AVIF has grown to approximately 90% of global traffic as of 2024, covering Chrome, Firefox, Safari (2023+) and Edge. For broader coverage, serve AVIF using the HTML <picture> element with a WebP or PNG fallback. This ensures modern browsers receive the smallest possible AVIF file while older browsers receive a compatible format. For png to avif online conversion aimed at modern web applications or sites with analytics-confirmed modern audiences, AVIF can be deployed as the primary format.
This png to avif online converter runs entirely in your browser. Your files never leave your device — no server upload, no third-party access, nothing retained. Upload any number of PNG files, convert all in parallel and download as individual AVIF files or a ZIP archive. No account, no file size limit, no daily cap — completely free.
You can also convert PNG to WebP for slightly broader browser support, compress the PNG directly to stay in PNG format, or convert JPG to AVIF for JPEG source images.
- 1Upload your PNG files

Each converted file displays the original PNG size and the AVIF output size. Download AVIF files individually or click "Download All" for a ZIP archive. AVIF files are ready to upload to your website, CDN or CMS.
- 4Deploy on your website with fallback
Upload the AVIF files to your server. For broad browser coverage, use the HTML <picture> element: serve AVIF to browsers that support it and WebP or PNG to others. For modern-browser audiences, AVIF can be served directly without a fallback.
Who converts PNG to AVIF — and why
Performance-focused developers — maximum compression for web graphics
For developers already using WebP who want the smallest possible web graphics, converting PNG to AVIF is the next step. AVIF delivers smaller files than WebP lossless for most graphic content — logos, icons and illustrations all compress further. Implement AVIF with a WebP fallback using the HTML <picture> element: modern browsers receive AVIF, others receive WebP. The result is the smallest possible image delivered to the widest audience.
Logo and icon optimization — transparent graphics as small as possible
Logos and icons are often PNG files with transparency — and they appear on every page of a website. Converting these to AVIF for website delivery minimizes their weight without any visual change. A 100 KB transparent PNG logo compressed to 60 KB as AVIF saves 40 KB on every single page load, for every visitor. For a site with 10,000 monthly visits averaging 3 pages each, that is 1.2 GB of saved bandwidth per month from a single logo conversion.
Modern web applications — future-proof image delivery
Progressive web apps and modern web applications targeting Chrome, Firefox and Safari users can serve AVIF as the primary image format without a fallback. For internal tools, dashboards and applications where the browser environment is controlled or analytics confirm a modern audience, AVIF is the best image format available. PNG to AVIF conversion for web applications reduces storage requirements and accelerates asset delivery from CDNs.
Illustrators and graphic designers — optimizing web exports
Designers exporting artwork, illustrations and graphics for web display often use PNG for its lossless quality and transparency support. Converting those PNG exports to AVIF before uploading to a website produces the smallest possible web-ready files while preserving every detail and transparent area. For portfolios, design showcases and client deliverables intended for web display, AVIF is the best format for combining maximum compression with visual fidelity.
Why use this PNG to AVIF converter
Maximum compression for web graphics with transparency, privacy-first processing, and batch capability.
AVIF is the smallest modern format — even for graphics with transparency
AVIF achieves the highest compression efficiency of any widely-supported format. For photographic PNGs, AVIF is typically 50% smaller than the PNG equivalent. For graphics and illustrations, AVIF outperforms WebP lossless, producing files smaller than WebP at comparable quality. Alpha transparency is fully supported — logos and icons convert to AVIF while preserving their transparent backgrounds exactly.
Your image files never leave your device
All conversion runs locally in your browser using JavaScript and the Canvas API. No file is uploaded to any server, transmitted over the network or stored anywhere. The tool works without an internet connection after the initial page load. Safe for client logos, brand assets under NDA and any content that cannot touch a third-party server.
Convert an entire PNG library to AVIF in one session
Upload as many PNG files as you need — there is no batch size limit. All files are processed in parallel in your browser. When all files are done, download them individually or use the "Download All" button to get a ZIP archive. Convert an entire icon set, logo library or design asset folder to AVIF in a single session.
PNG to AVIF on the web — complete guide
AVIF vs PNG vs WebP for graphics — choosing the smallest format
When choosing the best web format for graphics, logos and icons, the comparison between PNG, WebP and AVIF is important. PNG lossless is the most common format for graphics with transparency — every pixel is preserved, but files are large. WebP lossless improves on PNG by approximately 26% — a meaningful reduction for web delivery. AVIF goes further: AVIF supports lossless compression and, in many cases, produces files smaller than WebP lossless for graphics content. For photographic PNG images (less common), AVIF lossy compression is typically 50% smaller than the PNG equivalent. The best web format for graphics that need to be as small as possible on modern websites is AVIF, with WebP as the fallback for broader browser support. The practical hierarchy: PNG for editing and archival, WebP for reliable web delivery, AVIF for maximum compression on modern browsers. For png to avif for website optimization, AVIF delivers the smallest output of any option — particularly valuable for sites where every kilobyte of image weight affects performance scores.
Does AVIF support transparency? — PNG to AVIF without losing alpha
Yes — AVIF fully supports alpha transparency. This is one of the most important questions when considering whether to convert png to avif for logos and graphics that rely on transparent backgrounds. AVIF was designed as a full replacement for both JPG and PNG in web contexts, which means it supports the same alpha channel that PNG and WebP support. When you convert a PNG with a transparent background to AVIF, every transparent pixel is preserved exactly. Logos with cut-out backgrounds, icons with transparent shapes, and UI graphics with alpha gradients all convert to AVIF without any transparency information being lost. The AVIF output looks identical to the source PNG on any background color. Converting png to avif without losing quality for transparent graphics is safe and produces a smaller file than either PNG or WebP for the same content. The alpha channel in AVIF is encoded separately with high efficiency, making AVIF an excellent choice even for complex transparency patterns.
Browser support and fallback strategy for AVIF
AVIF browser support has expanded significantly: Chrome (2020+), Firefox (2021+), Safari (2023+) and Edge (2024+) all support AVIF, covering approximately 90% of global web traffic. For the remaining ~10% of users on older browsers, the recommended approach is to serve AVIF using the HTML <picture> element with a WebP or PNG fallback. The pattern is: <picture><source srcset="image.avif" type="image/avif"><source srcset="image.webp" type="image/webp"><img src="image.png" alt="description"></picture>. Modern browsers load the AVIF (smallest file), browsers without AVIF support load WebP, and legacy browsers fall back to PNG. This approach ensures the smallest possible file reaches the most browsers while maintaining full compatibility. For internal tools, progressive web apps and sites with analytics confirming a modern browser audience, AVIF can be deployed as the sole format without a fallback. For public-facing websites with mixed audiences, the <picture> element with fallback is the best practice.
