Does converting PNG to AVIF reduce image quality?

AVIF is a lossy format by default, so there is technically some quality reduction. However, at quality settings of 75-85, the difference is virtually imperceptible to the human eye. You can use the quality slider to find the perfect balance between file size and visual quality.

What quality setting should I use for PNG to AVIF?

For photographs and complex images, 75-85 provides an excellent balance of quality and compression. For simple graphics and screenshots, 60-70 works well. For maximum quality where file size is less important, use 90-95.

Is AVIF supported by all environments?

AVIF is supported by Chrome 85+, Firefox 93+, Edge 89+, Opera 71+, and Safari 16.4+. This covers over 93% of global environment usage. For older environments, you can serve PNG as a fallback using the HTML picture element.

Can I convert multiple PNG files to AVIF at once?

Yes, batch conversion is fully supported. Drag and drop multiple PNG files at once, and download all converted AVIF files individually or as a single ZIP archive.

Are my PNG files uploaded to a server?

No. All conversion happens entirely in your environment using the Canvas API. Your images never leave your device, ensuring complete privacy and security. No data is transmitted to any server.

Why Convert PNG to AVIF with Us?

Compress images by up to 10x — entirely in your environment, with full quality control.

Feature 01

Dramatic Compression — Up to 10x Smaller Files

AVIF uses the AV1 codec's advanced compression algorithms to achieve file sizes that are typically 5-10x smaller than the equivalent PNG. A 4MB product photo can become 400KB or less while maintaining near-identical visual quality. This translates directly to faster page loads, lower bandwidth costs, and better Core Web Vitals scores.

Feature 02

100% Private — Nothing Leaves Your Browser

Your PNG images are converted to AVIF entirely within your environment using the Canvas API. No files are uploaded to any server, no data is transmitted over the network, and no temporary copies are stored anywhere. The conversion engine runs in JavaScript on your device — even if you disconnect mid-conversion, it will still complete.

Feature 03

Batch Processing with One-Click ZIP Download

Converting a single image is easy — but what about 50? Drop your entire PNG collection at once. Each file is processed sequentially with a live progress indicator, showing the original size, compressed size, and savings percentage for every result. Grab everything as a single ZIP archive with one click.

Understanding PNG and AVIF Compression

Why AVIF?

AVIF (AV1 Image File Format) represents the cutting edge of image compression technology. Based on the AV1 video codec, AVIF achieves 50% better compression than JPEG and 20% better than WebP at equivalent visual quality. It supports HDR imaging, wide color gamut (10/12-bit), transparency, and even animation. AVIF is now supported by Chrome 85+, Firefox 93+, Edge 89+, and Safari 16.4+, covering over 90% of global environment usage. For web developers and content creators, AVIF means dramatically smaller file sizes without visible quality loss — translating directly to faster page loads and better user experience.

When to Keep PNG

PNG remains the best choice when you need absolute pixel-perfect lossless quality — such as for screenshots, technical diagrams, logos with sharp edges, or images that will undergo further editing. PNG's universal support means every application, environment, and device can display it without issues. However, PNG's lossless compression results in much larger files compared to modern lossy formats like AVIF, making it suboptimal for web delivery where bandwidth and loading speed matter.

When to Convert PNG to AVIF

Convert PNG to AVIF when you're preparing images for web delivery and want to minimize page weight. Blog post images, product photos, hero banners, and background images are ideal candidates. If the image will only be viewed on screen (not printed at high resolution) and doesn't need to be edited further, AVIF will deliver virtually identical visual quality at a fraction of the file size.
