What Is AVIF and Why Should You Convert PNG to AVIF?
AVIF (AV1 Image File Format) is the most advanced image format available for the web today. Developed by the Alliance for Open Media — the consortium behind companies including Google, Apple, Netflix, and Microsoft — AVIF was designed specifically to replace older formats like PNG and JPEG with dramatically smaller file sizes and superior quality.
When you convert PNG to AVIF, you are trading an older lossless format for a next-generation compressed format that uses the AV1 video codec under the hood. The result is stunning: AVIF images are typically 50–80% smaller than equivalent PNG files with no visible difference in quality to the human eye.
PNG vs AVIF — Key Differences
| Feature | AVIF ⭐ (Output) | PNG (Input) |
|---|---|---|
| File Size | 50–80% Smaller | Very Large |
| Compression Type | Lossy + Lossless | Lossless only |
| Transparency (Alpha) | ✓ Full Support | ✓ Full Support |
| HDR & Wide Color | ✓ Yes | ✗ No |
| Web Performance | Excellent | Slow (large files) |
| Browser Support | Chrome 85+, Firefox 93+, Safari 16+ | Universal |
| Best For | Web images, SEO, Core Web Vitals | Print, design files, editing |
| Open Standard | ✓ Royalty-Free | ✓ Royalty-Free |
AVIF supports full transparency (alpha channel) — just like PNG. If your PNG has a transparent background, converting it to AVIF preserves that transparency perfectly. You get all the benefits of AVIF with none of the PNG drawbacks.

Why Convert PNG to AVIF? 6 Reasons It's Worth Doing Right Now
PNG is a great format for editing and print. But for the web in 2025, AVIF is dramatically better. Here is exactly why.
Up to 80% Smaller File Sizes
A 2MB PNG image can become a 400KB AVIF file — with no visible difference in quality. Converting PNG to AVIF is the single fastest way to reduce your website's image payload and speed up page load times significantly.
Faster Page Load = Better Google Rankings
Google uses Core Web Vitals — including Largest Contentful Paint (LCP) — as a direct ranking factor. PNG images are large and slow. AVIF images load significantly faster, improving your LCP score and helping your pages rank higher in Google Search.
AVIF Passes Google PageSpeed Insights
Google PageSpeed Insights explicitly recommends serving images in AVIF or WebP format. When you convert your PNG images to AVIF and serve them on your website, you directly resolve the "Serve images in next-gen formats" warning — a common reason pages fail PageSpeed audits.
Supported by All Modern Browsers
AVIF is now supported by Chrome, Firefox, Safari, Edge, and Opera — covering over 95% of global web users. You can safely convert PNG to AVIF and serve AVIF images on your website with a simple PNG fallback for the remaining users.
Better E-Commerce Conversions
Product image pages with faster load times convert significantly better. Studies consistently show that a 1-second improvement in page speed increases conversions by 7–12%. Converting your product PNG images to AVIF is a direct, measurable improvement to your bottom line.
Lower Storage and Bandwidth Costs
Hosting costs scale with storage and bandwidth. If your CDN or hosting plan charges for data transfer, converting PNG to AVIF can cut your image bandwidth costs by 50–80%. For high-traffic websites serving millions of images, this means real, recurring savings every month.

PNG to AVIF Conversion Tips — Get the Best Results Every Time
Get more from your PNG to AVIF conversions with these tips from web performance experts and power users.
Use 75–85% Quality for Photographs
For PNG files that contain photographic content, a quality setting of 75–85% produces AVIF files that are visually indistinguishable from the original PNG while being dramatically smaller. Use the Before / After slider in the converter to verify before downloading.
Use 85–95% for Logos and Graphics
PNG files with sharp edges, text, or solid color blocks — such as logos, icons, and UI screenshots — need a higher quality setting to avoid compression artifacts. Use 85–95% quality or the Lossless preset for these file types when converting to AVIF.
Always Add a PNG Fallback for Older Browsers
AVIF has excellent browser support but is not universal. Use HTML <picture> elements with a PNG fallback so older browsers can still display your images: <source type="image/avif"> for modern browsers and <img src="image.png"> as the fallback.
Convert Before Uploading to WordPress
WordPress does not natively convert PNG to AVIF automatically. Convert your PNG files to AVIF using this tool first, then upload the AVIF files directly to your WordPress media library for the best results. This avoids relying on server-side processing plugins that may reduce quality.
Batch Convert Entire Image Libraries
Instead of converting PNG to AVIF one file at a time, use the batch feature. Drop an entire folder of PNG files into the converter, set your quality once, and convert everything together. The tool generates a ZIP file with all AVIF results for easy download and upload.
Use AVIF for Thumbnails and Preview Images
Thumbnail images and preview images appear on nearly every page of a website. Converting these from PNG to AVIF delivers the biggest page speed improvements because they are loaded most frequently. Even a modest 60% size reduction on 20 thumbnails per page dramatically cuts total page weight.
How to Convert PNG to AVIF for Your Website — Complete 2025 Guide
Everything you need to know about converting PNG to AVIF and using AVIF images on your website in 2025.
Is AVIF Better Than PNG for Websites?
Yes — for almost every web use case, AVIF is significantly better than PNG. PNG was designed in 1996 primarily as a lossless format for digital graphics and print. It excels at preserving every pixel perfectly, which makes it ideal for design files, editing workflows, and screenshots.
But on the web, PNG's lossless nature is its biggest drawback. PNG files are very large, which means slower page loads, higher bandwidth costs, and worse scores on Google PageSpeed Insights. AVIF solves all of this: it offers both lossy and lossless compression options, supports full transparency, and produces files that are 50–80% smaller than equivalent PNG files.
Does Converting PNG to AVIF Lose Quality?
It depends on the quality setting you choose. At 100% quality or using the Lossless preset, PNG to AVIF conversion produces pixel-perfect results with no quality loss at all — while still reducing file size by 20–40% compared to the original PNG.
At lower quality settings (75–85%), PNG to AVIF conversion introduces very minor lossy compression that is invisible to the human eye in virtually all real-world images. This is the recommended setting for most website images — you get dramatically smaller files with no perceptible quality difference.
How to Use AVIF Images in WordPress
WordPress has supported AVIF image uploads since WordPress 6.5 (released in April 2024). To use AVIF images on your WordPress site:
- Convert your PNG images to AVIF using this free converter
- Upload the converted AVIF files to your WordPress Media Library
- Use AVIF images in posts, pages, and theme templates as normal
- For maximum compatibility, use a picture element with a PNG fallback
PNG to AVIF Conversion on Shopify
Shopify automatically serves images in WebP format where supported, but does not automatically convert PNG to AVIF. To use AVIF images on your Shopify store, convert your PNG product images to AVIF using this tool and upload the AVIF files directly to your Shopify product pages. This gives you full control over AVIF quality and ensures optimal file sizes.
Does AVIF Support Transparent Backgrounds?
Yes. AVIF fully supports alpha channel transparency. When you convert a PNG file with a transparent background to AVIF, the transparency is preserved in the output AVIF file. You can use transparent AVIF images for logos, product cutouts, UI overlays, and any other use case where you currently rely on transparent PNG files.
For maximum browser compatibility: Use the HTML <picture> element to serve AVIF to browsers that support it and PNG to browsers that do not. This approach is supported by all modern AVIF-compatible browsers and provides a seamless fallback for older ones.
