PNG to AVIF

How to use the PNG to AVIF

1. 1Select your PNG files or drop them onto the page.
2. 2Pick a quality. 60% suits most screenshots and logos; raise it for fine text.
3. 3Wait for the conversion. Each row shows the new file size and the saving.
4. 4Download individual AVIF files or all of them as a ZIP.
5. 5Look at the results on the page where you plan to use them.

What makes PNG files big

PNG is built for exact copies, so every pixel is kept even when your eyes would never notice. Screenshots, charts and photographs saved as PNG can reach several megabytes. AVIF can store the same picture with intelligent compression, usually at a small fraction of the size.

Screenshots, logos and cut-outs

Flat graphics compress very well: a screenshot of a 1.2 MB PNG may drop below 150 KB. For logos with sharp edges and text, use a quality near 75 and zoom in to check. Photos with transparent backgrounds, like product cut-outs, benefit the most, because the alpha channel is stored efficiently.

• 60%: screenshots and illustrations
• 75%: logos and thin text
• 90%+: only when edges must be crisp

Using the files on a website

Reference AVIF files in an image or picture element and keep the PNG as a fallback for very old browsers. Because transparency survives, the same file can sit on light and dark backgrounds.

Phone and computer

On a phone you can convert screenshots straight from your gallery. On a computer, drop many files at once and download the ZIP. Large images take a few seconds each because AVIF encoding is thorough.

Good to know

Animated PNG files become a still picture. Very large images, above about 50 megapixels, may be slow on older phones. The first run loads the encoder, which is about 3.5 MB, and the browser keeps it afterwards.

A worked example

Imagine a 1,600 by 900 pixel product cut-out saved as PNG at 2.4 MB. Converted at 60 percent it is typically around 150 to 300 KB, and it still sits cleanly on a white or coloured background because the transparency is kept. A page with twenty such pictures drops from about 48 MB to under 6 MB, which is the difference between a slow and a quick page on a phone connection.

If a result looks too soft on text, open the original next to it, raise the quality by ten points and convert again. The tool processes your files again automatically when you move the slider. AVIF can save a lot of space, and other formats suit older apps. Convert photos with JPG to AVIF, use PNG to WebP for wider support, and run the original through Compress Image first when it is very large.
