Why Convert?

When Should You Convert PNG to AVIF?

Convert PNG images to AVIF when you want smaller files, faster website loading, reduced bandwidth usage, modern compression, or transparent images optimized for current browsers and digital platforms.

Advanced Image Compression

AVIF uses modern AV1-based compression to create significantly smaller files than many PNG images while retaining strong visual quality.

Transparency Support

AVIF supports alpha transparency, allowing transparent and semi-transparent areas from compatible PNG images to remain in the converted output.

High Visual Quality

AVIF can efficiently preserve detailed textures, smooth gradients, sharp edges, and natural colors at reduced file sizes.

Modern Web Performance

Smaller AVIF files can reduce page weight, improve image delivery, save bandwidth, and help websites load faster on supported browsers.

Format Comparison

PNG vs AVIF: Which Format Should You Choose?

PNG and AVIF are raster image formats with different strengths. PNG uses lossless compression and is widely used for transparent graphics, screenshots, and sharp interface elements. AVIF provides modern lossy and lossless compression, transparency support, advanced color capabilities, and smaller output files in many cases.

FROM PNG

TO AVIF

Feature	PNG	AVIF
Ideal Uses	Ideal for logos, icons, screenshots, interface graphics, illustrations, and images requiring transparent backgrounds	Ideal for optimized websites, online stores, web applications, image galleries, and bandwidth-efficient transparent graphics
Compression Method	Uses lossless compression to preserve the original pixel data without introducing compression artifacts	Supports modern lossy and lossless AV1-based compression for flexible control over output quality and file size
Transparency Support	Supports full and partial transparency through an alpha channel	Also supports alpha transparency while allowing the image to be stored with more efficient compression
File Size	Can produce large files when images contain photographs, complex textures, gradients, or many colors	Often creates considerably smaller files than PNG while maintaining similar visible detail and transparency
Compatibility	Supported by nearly every browser, operating system, device, image editor, and digital platform	Supported by modern browsers and updated image software, but compatibility may be limited on older systems
Visual Results	Keeps sharp text, clean edges, flat colors, screenshots, and transparent graphics free from lossy artifacts	Can retain detailed visuals and smooth gradients efficiently, although lossy settings may slightly alter pixel-level details
Web Delivery	Provides dependable browser display but large PNG files can increase page weight and loading time	Reduces image transfer size and can improve page loading speed for visitors using compatible browsers

Quick Tip: Use PNG when universal compatibility, exact pixel preservation, and lossless editing are essential. Use AVIF when you need smaller transparent images, modern compression, reduced bandwidth usage, and faster website delivery.

AVIF

Upload your PNG image, select AVIF as the output format, choose a quality setting if available, start the conversion, and download the converted AVIF file.

Yes, AVIF supports alpha transparency. Transparent and semi-transparent areas can remain in the output when the converter preserves the PNG alpha channel.

In many cases, AVIF can create a much smaller file than PNG, especially for photographs, detailed graphics, gradients, and images containing many colors.

The result depends on the selected compression mode and quality setting. Lossless AVIF can preserve pixel data, while lossy AVIF may remove some information to create a smaller file.

AVIF is often better when reducing page size and bandwidth is important. PNG remains useful when universal compatibility, exact pixel preservation, or editing support is the main priority.

Yes, when batch conversion is supported, you can upload and convert multiple PNG images into separate AVIF files simultaneously.
