Upload a PNG file, choose optional quality, lossless, or size settings, then start the conversion. When the task finishes, download the converted .avif file.
PNG to AVIF Converter
Convert PNG to AVIF when you need a modern .avif image from a .png source. Upload a PNG file, choose a quality level or lossless mode, resize the output if needed, and download the converted AVIF file. This PNG to AVIF converter is useful for web graphics, transparent images, screenshots, icons, and other PNG assets that need a smaller delivery format.
What This PNG to AVIF Converter Does
This tool takes a PNG image and re-encodes it as an AVIF file. AVIF is a modern image format built for strong compression, so it can be a good output choice when you want lighter website images without changing the source format by hand.
The converter gives you a few practical controls before export:
| Setting | What it does | When to use it |
|---|---|---|
| Quality 30-40 | Prioritizes smaller AVIF files | Thumbnails, previews, and images where file size matters most |
| Quality 50 | Balanced default setting | General web graphics, article images, and UI screenshots |
| Quality 60-80 | Keeps more visual detail | Large images, gradients, product visuals, and important screenshots |
| Lossless mode | Avoids lossy AVIF compression | Logos, icons, text-heavy screenshots, and sharp edges |
| Width and height | Resizes the output during conversion | Creating a display-size AVIF instead of keeping an oversized PNG |
This is a real PNG to AVIF conversion, not a file rename. A renamed .png file still contains PNG image data internally, while this tool creates an actual .avif output.
How to Convert PNG to AVIF Online
1
Step 1: Upload your PNG file
Choose a .png file from your device or drag it into the upload area. The page is focused on PNG input, so the upload field accepts PNG files for this conversion workflow.
2
Step 2: Choose quality, lossless mode, or size
Keep the default quality setting for a balanced result, lower the quality when you need a smaller file, or raise it when the image has gradients, text, edges, or important detail. Use lossless mode when you want to avoid lossy AVIF compression. Enter a width or height if the final image should be resized during conversion.

Step 3: Convert and download the AVIF file
Start the conversion and wait for the AVIF output to finish. AVIF encoding can take a little longer than older image formats, but the result is a downloadable .avif file ready for supported browsers and modern web workflows.
Why Convert PNG to AVIF?
PNG is reliable, widely supported, and excellent for transparent graphics. Its tradeoff is file size: PNG can become heavy for screenshots, graphics, and high-resolution web assets. AVIF is designed for stronger compression, which can make the final image lighter for modern web delivery.
| Need | Why AVIF helps |
|---|---|
| Smaller web assets | AVIF can often reduce image weight compared with an equivalent PNG |
| Transparent graphics | AVIF supports alpha transparency, so it can be used for transparent web images |
| Controlled export quality | Quality settings let you balance file size and visible detail |
| Right-sized images | Optional width and height fields help avoid serving oversized graphics |
| Modern browser delivery | AVIF works well in current browsers that support the format |
The best use case is straightforward: keep your original PNG as the source file, then use an AVIF copy when you need a smaller modern delivery asset for a website, app interface, or content image.
PNG and AVIF: What Changes During Conversion
PNG commonly uses lossless compression and is a dependable format for graphics, screenshots, interface elements, and transparent images. AVIF is different: it is built on newer compression technology and can use either lossy or lossless encoding.
| Format point | PNG | AVIF |
|---|---|---|
| Typical use | Source graphics, screenshots, transparent assets | Optimized modern web delivery |
| Compression | Lossless PNG compression | Lossy or lossless AVIF compression |
| Transparency | Supports alpha transparency | Supports alpha transparency |
| Browser support | Very broad | Strong in modern browsers, weaker in older browsers |
| Editing workflow | Good as a source or working file | Better as a delivery/export format |
That difference matters when writing web images. PNG is often a good source format to keep. AVIF is often a good final format to serve when browser support and file size are priorities.
Best PNG to AVIF Settings
The right setting depends on the content of the PNG. A flat icon, a transparent logo, a UI screenshot, and a full-width illustration should not all use the same export settings.
| Output goal | Suggested setting | Why it helps |
|---|---|---|
| Small thumbnails | Quality 40-50 | Keeps the file compact while staying clear at small sizes |
| UI screenshots | Quality 60-80 or lossless | Protects text, lines, and sharp interface edges |
| Transparent logos or icons | Lossless or higher quality | Helps keep edges cleaner around transparent areas |
| Large web graphics | Resize plus quality 50-70 | Controls both dimensions and compression |
| Maximum file reduction | Quality 30-40 | Prioritizes smaller output when detail is less critical |
If you are unsure, start with the default quality value, download the AVIF file, and compare it with the original PNG at the size where it will actually appear. Judging from an extreme zoom level can make small artifacts look more important than they will be in the final layout.
Transparent PNG to AVIF
AVIF supports alpha transparency, so it is a suitable output format for many transparent PNG images. That makes PNG to AVIF useful for logos, interface icons, badges, product overlays, and graphics that need to sit on different backgrounds.
For transparent artwork, use a higher quality setting or lossless mode if the edges matter. Thin outlines, antialiasing, soft shadows, and semi-transparent pixels can make artifacts easier to notice, especially when the AVIF is placed over a dark or patterned background.
After downloading the result, preview the AVIF on the background where it will be used. That is the safest way to check whether transparent edges, shadows, and fine details still look right in context.
When to Use PNG to AVIF
Use this converter when the source file is PNG and the final asset should be a smaller modern image for web delivery. It is especially useful when a PNG is visually correct but too large for a page, article, product card, or interface.
Website graphics
AVIF can reduce page weight for supported browsers
App UI screenshots
Resizing and quality settings help prepare clean documentation images
Transparent badges or icons
AVIF can carry transparency while using newer compression
Blog and help center images
Smaller delivery files can make content pages lighter
Product or landing page visuals
AVIF can keep detailed images manageable for modern browsers
Do not use this page when the source file is AVIF and you need PNG output, or when the source is JPG, WebP, GIF, HEIC, SVG, or TIFF. In those cases, use a converter that matches the actual input format.
Frequently Asked Questions
A PNG to AVIF converter re-encodes a .png image into the .avif format. The goal is usually to create a smaller modern image file for websites, interfaces, and other web use cases.
Yes. This page lets you convert PNG to AVIF online from a web interface. You do not need to install desktop image software to create the AVIF output.
AVIF supports transparency, and transparent PNG images can often keep alpha transparency in AVIF output. For important transparent edges, use a higher quality setting or lossless mode and preview the result on the intended background.
Use lossy AVIF when smaller file size matters most. Use lossless mode for logos, icons, screenshots, text-heavy images, and sharp graphics where preserving decoded detail is more important than maximum compression.
Start with quality 50 for a balanced result. Use 30-40 for smaller files, 60-80 for cleaner detail, and lossless mode when the image contains text, thin lines, or transparency that needs extra care.
Yes. You can enter a target width or height before converting. Resizing during conversion is useful when the original PNG is larger than the final display size.
Often, yes, especially for web images that do not need to remain in a source-editing format. The exact result depends on the image content, dimensions, quality setting, and whether you choose lossy or lossless AVIF.
No. The selected file is uploaded for backend processing, then the converted AVIF output is returned for download. Avoid uploading private, regulated, or sensitive images if you are not comfortable sending them to a conversion service.
Yes. Keep the original PNG as your source or fallback file, especially if you may need to export another size, adjust quality settings, or support older environments that do not use AVIF.
