Convert PNG to AVIF Online
ToolzNova’s PNG to AVIF Converter allows you to convert PNG images into the modern AVIF image format directly in your web browser. The tool is designed for users who want smaller image files without sacrificing too much visual quality.
PNG is widely used for graphics, screenshots, logos, illustrations, and images that require transparency. However, PNG files can sometimes become very large. AVIF uses modern image compression technology and can often create significantly smaller files, making it useful for websites and other digital projects.
How to Convert PNG to AVIF
- Click Choose PNG File or drag your PNG image into the upload area.
- Select your preferred AVIF quality level.
- Click Convert to AVIF.
- Wait for the browser to process your image.
- Click Download AVIF to save the converted image.
There is no complicated software to install. The conversion process takes place through your browser when AVIF encoding is supported.
Why Convert PNG to AVIF?
Smaller File Sizes
AVIF can provide strong compression, helping reduce the amount of storage and bandwidth required for images.
High Image Quality
Modern AVIF compression can preserve impressive visual quality even when an image is compressed to a smaller size.
Better for the Web
Smaller images can improve page-loading performance and create a faster experience for website visitors.
PNG vs AVIF: What Is the Difference?
PNG is a lossless image format that is especially popular for screenshots, graphics, logos, and transparent images. It preserves image details well, but that can result in comparatively large files.
AVIF is a newer image format based on AV1 image compression. Its main advantage is efficient compression. Depending on the source image and quality setting, an AVIF image may require much less storage than its PNG equivalent.
When Should You Keep PNG?
PNG can still be a good choice when compatibility is your main priority or when you need a lossless source image for editing and archival purposes.
When Should You Use AVIF?
AVIF is particularly useful for website images where reducing page weight and improving loading performance are important. You may also want to keep the original PNG as a source file and use the AVIF version for web delivery.
Does AVIF Support Transparency?
Yes. AVIF can support transparency, making it suitable for many of the same types of images that commonly use transparent PNG backgrounds.
Actual browser-side encoding behavior can vary by browser, so you should always inspect your converted image when transparency is important to your design.
What AVIF Quality Should I Use?
The best quality setting depends on the image. A quality setting around 70% to 85% is a useful starting point for many web images.
- 90–100%: Higher quality with larger files.
- 70–89%: Good balance for many website images.
- 40–69%: Stronger compression and smaller files.
- 10–39%: Very small files but visible quality loss may occur.
Try different settings and compare the resulting file size and visual quality before deciding which version to publish.
Benefits of AVIF Images for Websites
Images often account for a large portion of a web page’s total download size. Optimizing them can therefore have a meaningful impact on website performance.
Converting suitable PNG files to AVIF can help reduce image weight, especially on pages containing many graphics or large images. Smaller assets can require less bandwidth and may load more quickly for users on slower connections.
Is This PNG to AVIF Converter Free?
Yes. This ToolzNova PNG to AVIF Converter is designed to be used online without requiring image-editing software. You can choose a PNG file, adjust the quality, convert it, and download the resulting AVIF image.
Are My PNG Images Uploaded?
This version of the converter processes the selected image inside the browser using browser image capabilities. The conversion code does not intentionally send your selected image to a separate image conversion server.
Frequently Asked Questions
How do I convert PNG to AVIF?
Upload your PNG image, choose the desired quality, click Convert to AVIF, and download the resulting AVIF file when conversion is complete.
Can I convert PNG to AVIF for free?
Yes. You can use this converter without purchasing desktop image conversion software.
Will converting PNG to AVIF reduce file size?
It often can. The exact reduction depends on the original PNG, image complexity, dimensions, transparency, and the AVIF quality setting you select.
Does AVIF have better compression than PNG?
AVIF is designed around modern compression technology and can often produce much smaller files than PNG, particularly when lossy compression is acceptable.
Can AVIF images have transparent backgrounds?
Yes. The AVIF format supports transparency, although browser-side encoding support should be tested for your particular use case.
Why is my browser unable to create an AVIF file?
Browser support for displaying AVIF and browser support for encoding AVIF through Canvas are not always the same. If your browser cannot encode AVIF, this tool will display a compatibility message instead of incorrectly downloading another format with an .avif extension.
Should I delete my original PNG after conversion?
Keeping the original PNG is usually useful, especially if it is your source or master image. You can use the smaller AVIF copy for website delivery while retaining the PNG for future editing.
