When to Convert PNG to AVIF

Web Performance Optimization

Convert PNG assets to AVIF for production websites. AVIF files are 40–60% smaller than PNG, dramatically reducing page weight and improving Core Web Vitals LCP scores for faster page loads.

CMS & Blog Image Optimization

Convert PNG images to AVIF before uploading to WordPress, Webflow, or any CMS. Smaller AVIF files reduce storage costs and improve page load times without any visible quality loss.

Next.js & Modern Web Apps

Convert PNG assets to AVIF for Next.js, Nuxt, or Astro projects. Modern frameworks serve AVIF with automatic WebP and JPEG fallbacks — converting your source PNGs to AVIF maximises compression.

E-Commerce Product Images

Convert PNG product images to AVIF to reduce page weight on product listing and detail pages. Faster-loading product images improve conversion rates and reduce bounce rates on mobile devices.

Design Asset Export

Convert PNG exports from Figma, Sketch, or Photoshop to AVIF for web delivery. AVIF preserves transparency and sharp edges while achieving dramatically smaller file sizes than PNG.

PageSpeed & Core Web Vitals

Eliminate 'Serve images in next-gen formats' PageSpeed warnings by converting PNG to AVIF. AVIF is Google's recommended next-gen format and directly addresses the most common image optimization audit failure.

Understanding PNG to AVIF Compression

What is PNG to AVIF Conversion?

Converting PNG to AVIF means re-encoding a PNG image using the AVIF (AV1 Image File Format) codec — the most advanced image compression format available in modern browsers. AVIF is based on the open-source AV1 video codec developed by the Alliance for Open Media and achieves 40–60% smaller file sizes than PNG at the same visual quality. Unlike PNG (which is lossless), AVIF uses perceptual compression to discard image data that is imperceptible to the human eye. Our PNG to AVIF compressoruses the browser's native canvas API to encode AVIF directly — no server uploads, no WASM dependencies, complete privacy.

How Our PNG to AVIF Compressor Works

  1. 1Upload Your PNG Files: Drag and drop or click to select PNG files. The tool accepts up to 20 files for batch processing. All processing happens locally in your browser — your PNG files never leave your device.
  2. 2Set Your Quality Level: Adjust the quality slider (75–85% recommended). The tool detects whether your browser supports AVIF encoding and shows the output format. If AVIF is not supported, it automatically falls back to WebP — still 25–40% smaller than PNG.
  3. 3Download Converted Files: Each file shows the size reduction achieved. Download individually or as a ZIP archive. Files are named with the correct extension (.avif or .webp) for immediate use in your project.

PNG vs. AVIF — Size Comparison

  • PNG (lossless): Largest file size — no quality loss, but no perceptual compression. Best for screenshots and UI assets where pixel-perfect accuracy is required.
  • WebP (lossy): 25–35% smaller than PNG at matched visual quality. Supported by all modern browsers. Good fallback when AVIF is not available.
  • AVIF (lossy): 40–60% smaller than PNG at matched visual quality. Supported by Chrome, Firefox, and Edge. The best choice for web delivery when browser support allows.
  • Transparency: AVIF fully supports alpha channel transparency — logos, icons, and UI assets with transparent backgrounds convert correctly.

Browser Support for AVIF

AVIF encoding via the browser canvas API is supported in Google Chrome, Mozilla Firefox, and Microsoft Edge. Safari has limited AVIF canvas encoding support. Our PNG to AVIF compressor automatically detects your browser's AVIF support and falls back to WebP if needed — you always get the best compression available in your browser. For production use, serve AVIF with a WebP or JPEG fallback using the HTML <picture> element or Next.js Image component.

Frequently Asked Questions About PNG to AVIF Compressor

A PNG to AVIF compressor converts PNG images to AVIF format — the most advanced image compression format available in modern browsers. AVIF files are typically 40–60% smaller than PNG at the same visual quality. Our free PNG to AVIF compressor online processes everything locally in your browser with no server uploads.

Typical size reductions range from 40–60% compared to the original PNG. The exact reduction depends on the image content and quality setting. Flat-color illustrations and UI graphics compress more than photographic images. At 80% quality, most PNG files convert to AVIF at 40–55% of their original size.

Absolutely. Our PNG to AVIF compressor online processes everything 100% client-side in your browser. Your PNG files never leave your device and are never transmitted to or stored on our servers. This makes it safe for converting proprietary design assets, product images, and confidential graphics.

Yes — our PNG to AVIF compressor is 100% free, forever. No file size limits, no batch limits, no watermarks, no sign-up, and no hidden premium tiers. You can convert as many PNG files as your device memory allows.

The tool automatically detects your browser's AVIF support and falls back to WebP if AVIF encoding is not available. WebP still achieves 25–40% smaller files than PNG at the same visual quality. The tool clearly shows which output format is being used before you convert.

Yes. AVIF fully supports alpha channel transparency. Logos, icons, and UI assets with transparent backgrounds convert correctly to AVIF with full transparency preserved. This makes AVIF an excellent replacement for PNG in web projects that require transparent images.

For most web images, 75–85% quality delivers the best balance between file size and visual quality. At 80%, AVIF files are typically 40–55% smaller than the original PNG with no perceptible quality difference. For images with fine detail or text, use 85–90% to preserve sharpness.

AVIF is supported by Google Chrome, Mozilla Firefox, and Microsoft Edge. Safari has partial support. For production web use, always serve AVIF with a WebP or JPEG fallback using the HTML <picture> element or a framework like Next.js that handles format negotiation automatically.

Yes. Upload up to 20 PNG files and click "Convert to AVIF" to process the entire queue. Download all results as a single ZIP archive or individually. Files are named with the correct .avif (or .webp) extension for immediate use in your project.
