What is AVIF and why convert PNG to AVIF?

AVIF (AV1 Image File Format) is a modern image format that delivers significantly smaller file sizes than PNG while maintaining excellent visual quality. Converting PNG to AVIF is ideal for web optimization — AVIF files are typically 50–80% smaller than equivalent PNGs, which improves page load speed and Core Web Vitals scores.

Does converting PNG to AVIF lose quality?

At quality settings of 80 and above, AVIF output is visually near-identical to the PNG source. AVIF uses a perceptually optimized codec (AV1) that preserves detail far better than JPG at equivalent file sizes. For lossless output, use quality 100.

Does my data get uploaded to a server?

Never. All PNG decoding and AVIF encoding happens entirely in your browser using the Canvas API. Your images never leave your device.

Which browsers support AVIF?

AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. It covers over 90% of global browser usage as of 2026. For legacy compatibility, serve WebP or JPG as fallbacks using the HTML picture element.

How It Works

Drop your PNG filesDrag multiple .png files onto the drop zone, or click Browse Files. Thumbnails generate immediately.

Set your qualityUse the quality slider (1–100). 80 is the default — great balance of size and quality for web images.

Click Convert to AVIFThe browser's Canvas API encodes each PNG to AVIF in memory. A progress bar tracks per-file completion.

Download your AVIFsDownload files individually or check "Download as ZIP" for a single timestamped archive.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. PNG files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for private design assets, internal documents, or client images.

Frequently Asked Questions

What quality setting should I use?▼

For web images, quality 75–85 offers the best balance of file size and visual fidelity. Use 90+ for archiving or photography. Use 60–70 for thumbnails or images where file size is critical. Quality 100 produces a near-lossless AVIF.

Does AVIF support transparency like PNG?▼

Yes — AVIF supports full 32-bit RGBA transparency. If your PNG has a transparent background, that transparency will be preserved in the AVIF output. This makes AVIF a drop-in replacement for PNG in modern browsers.

Can I convert multiple PNG files at once?▼

Yes — drop as many files as you like. The tool processes them sequentially, shows per-file status badges, and lets you download all AVIFs individually or as a single timestamped ZIP.

My browser doesn't support AVIF encoding — what happens?▼

The Canvas API's toBlob method with 'image/avif' is used for encoding. If your browser doesn't support AVIF encoding (older Chrome, older Firefox), you'll see an error on that file. Use Chrome 94+ or Firefox 93+ for best results.

Is this tool free with no limits?▼

Yes — completely free with no file size limits, no per-conversion limits, and no account required. Processing happens in your browser so we never see your files.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_png_to_avif_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_png_to_avif_202603081200.zip.
