How to Convert PNG to AVIF and Keep Transparency

Do you have a PNG image with a transparent background that takes up too much space? You can convert PNG to AVIF to make the file smaller while keeping its transparent areas. This is useful for website logos, product pictures, icons, and other graphics.

AVIF is a modern image format that can reduce file size without making an image look very different. It also supports transparent backgrounds, just like PNG.

However, not every converter handles transparency in the same way. In this guide, you will learn how to convert PNG to AVIF without losing transparency, check image quality, and fix common conversion problems.

How to Convert PNG to AVIF Without Losing Transparency

The easiest way to convert a PNG image is to use an online image converter that supports transparent backgrounds.

Follow these simple steps:

1. Open the QuickConvertPDF PNG to AVIF converter.

2. Click Choose PNG images to select your picture.

3. Make sure the original PNG has a transparent background.

4. Click Convert to AVIF to start the conversion.

5. Save the converted AVIF file when it is ready.

6. Open your new image and check that the background is still transparent.

That's it! You can now use your AVIF image on a website or in another application that supports the format.

Quick tip: Keep your original PNG file. It will be useful if you need to edit the image or convert it again.

What Are PNG and AVIF Image Formats?

Before changing your image, it helps to understand what these two formats do.

What Is a PNG File?

PNG stands for Portable Network Graphics. It is a popular image format used for logos, screenshots, drawings, and website graphics.

One of its best features is transparency. A PNG image can have a clear background, allowing you to place it over different colors without showing a white box around it.

PNG also uses lossless compression. This means the image keeps its original pixel details when it is saved.

The main problem is file size. Some PNG images are much larger than they need to be, especially when they contain detailed artwork.

What Is an AVIF File?

AVIF stands for AV1 Image File Format. It is a newer image format designed to store pictures more efficiently.

AVIF can create smaller files while keeping good visual quality. It supports transparency, rich colors, and both lossy and lossless compression.

Lossy compression removes some image data to reduce file size. Lossless compression keeps that data.

This makes AVIF a useful choice for modern websites that need clear images without large downloads.

Why Convert PNG to AVIF?

Changing PNG images to AVIF can offer several benefits.

Smaller image files: AVIF often uses less storage space than PNG, especially for detailed images.

Faster image downloads: Smaller files can take less time to load on a website, particularly on slower internet connections.

Transparent backgrounds: AVIF supports transparency, making it useful for logos, icons, and product images.

Good visual quality: With suitable compression settings, an AVIF image can look very similar to its original PNG.

Less data usage: Smaller images can reduce the amount of data visitors download.

However, AVIF is not always smaller than PNG. Results depend on the image, its colors, and the conversion settings.

How to Convert PNG to AVIF Online Using QuickConvertPDF

You do not need advanced photo-editing skills to change an image format. A browser-based converter can handle the process in a few steps.

Step 1: Open the PNG to AVIF Converter

Visit the PNG to AVIF online tool on QuickConvertPDF.

The page has a simple file selection area and a conversion button. You can use it from a computer or another device with a supported browser.

Step 2: Choose Your PNG Image

Click Choose PNG images and find the PNG file on your device.

You can select a logo, icon, illustration, or another PNG graphic.

The tool's published limit allows up to 30 images, with a maximum size of 25 MB per image.

Before selecting your file, check whether its background is already transparent. If the image has a solid white background, converting it will not automatically remove that background.

Step 3: Start the Conversion

After choosing your image, click Convert to AVIF.

The converter will process your PNG and create a file in AVIF format.

The time needed depends on the image size and the work required to encode it.

Step 4: Save and Check Your AVIF Image

Save the converted file to your device.

Open it in a browser or image application that supports AVIF. Look closely at the background and the edges of the picture.

If everything looks correct, your PNG to AVIF with transparency conversion is complete.

For important graphics, compare the new file with the original before replacing it on your website.

How Does AVIF Keep Transparent Backgrounds?

A transparent background means you can see what is behind an image.

For example, imagine a red logo placed on a blue website. If the logo has a transparent background, you see only the red design against the blue page.

This works because the image contains information called an alpha channel.

An alpha channel tells the image which parts should be visible, hidden, or partly transparent.

Both PNG and AVIF support alpha channels. This allows a transparent PNG to AVIF conversion to keep clear backgrounds and soft edges.

However, the converter must correctly transfer this information. A converter that removes the alpha channel may replace transparent areas with a solid color.

That is why checking the result is important.

Best Settings to Preserve Transparency in AVIF

Choosing suitable settings can help protect image quality during conversion.

Not every PNG to AVIF converter offers the same controls, so use the options available in your chosen tool.

Choose a High-Quality Setting

If the converter has a quality control, start with a high setting.

This can help keep text, shapes, and fine details looking clear.

Very low-quality settings may create blurry edges or unwanted marks around an image.

Use Lossless Conversion When Needed

AVIF supports lossless compression, but not every converter offers it.

Lossless conversion can be useful for logos, diagrams, and images with sharp lines.

For ordinary website graphics, high-quality lossy compression may provide a good balance between size and appearance.

QuickConvertPDF's PNG to AVIF tool uses lossy AVIF compression, so keep the original PNG when exact pixel details matter.

Keep the Original Image Dimensions

Avoid changing the width and height unless you need a smaller image.

Reducing dimensions can remove fine details. Enlarging a small image does not restore missing detail.

If you need extra control over image quality or resolution, CloudConvert's PNG to AVIF converter is another option that provides conversion settings.

Remember, preserving transparency does not always mean preserving every pixel exactly. The background may remain clear even when lossy compression slightly changes the visible artwork.

How to Check Whether AVIF Transparency Is Preserved

After conversion, take a moment to inspect your image.

First, open the AVIF file in a supported image viewer. Some applications show a checkerboard pattern behind transparent areas.

That pattern is a visual guide. It is not part of the picture itself.

Next, place the image over a dark background. Look for white lines, strange colors, or a solid box around the design.

Then try a light background. This can reveal problems that were difficult to notice on the dark one.

Pay special attention to hair, shadows, curved edges, and small text. These areas may show changes after lossy compression.

You can also compare the file sizes of the PNG and AVIF versions.

A smaller file is useful, but a clear image with the correct background matters more than saving a few extra kilobytes.

Common PNG to AVIF Problems and How to Fix Them

Sometimes a converted image does not look the way you expected. Here are some common problems and their solutions.

1. The AVIF Image Has a White Background

A white background can appear if the original picture was not transparent or the converter removed its alpha channel.

Open the original PNG and check its background. If it is already white, you must remove that background before converting.

If the PNG is transparent, try a converter that supports alpha transparency and check the result again.

2. The Image Has Blurry or Rough Edges

This may happen when a converter uses strong lossy compression.

Try a higher quality setting if one is available. You can also choose lossless AVIF encoding in a tool that supports it.

For small logos and icons, keeping the original PNG may sometimes give a better result.

3. The AVIF File Does Not Open

Some older apps and devices do not support AVIF files.

Try opening the picture in an updated version of Chrome, Firefox, Safari, or Edge.

If your application still cannot read it, use the PNG version or convert the AVIF into a more widely supported format.

4. The Converted File Is Larger Than the PNG

AVIF often produces smaller files, but this is not guaranteed.

A simple icon with only a few colors may already be very small as a PNG.

Different compression settings can also change the final size.

Compare both versions and choose the one that works best for your needs.

PNG vs AVIF: Which Format Is Better for Transparency?

Both image formats support transparent backgrounds. Their main differences are file size, compression, and compatibility.

Feature	PNG	AVIF
Transparency	Yes	Yes
Compression	Lossless	Lossy and lossless
File size	Often larger	Often smaller
Image quality	Exact pixel details	Depends on settings
Browser support	Very broad	Modern browsers
Best use	Editing and original graphics	Optimized website images

If your main goal is smaller website images, AVIF is worth trying.

If you need an original graphic for repeated editing, PNG is often the safer choice.

You can also keep both versions: one for editing and one for use on your website.

When Should You Keep PNG Instead of AVIF?

AVIF is useful, but there are times when keeping PNG makes more sense.

For example, a designer may need to edit a logo many times. Keeping the original PNG avoids repeated lossy conversions.

PNG is also a good choice when an older program cannot open AVIF files.

Small icons, diagrams, and images with tiny text may not become much smaller after conversion. In those cases, PNG can be easier to work with.

The best format is the one that gives you the quality, file size, and compatibility you need.

Other Ways to Convert Transparent PNG Images to AVIF

Several online services support PNG to AVIF conversion.

The SpeedVitals PNG to AVIF tool offers conversion controls such as image quality and resizing. These can be helpful when you want to compare file sizes and visual results.

Another option is the Piknova PNG to AVIF converter, which offers browser-based conversion and describes how it handles transparent images.

Different services may have different file limits, settings, and privacy practices.

No matter which PNG to AVIF converter you choose, always check the downloaded image before using it in an important project.

Is AVIF Good for Website Images?

AVIF can be a good option for modern websites because it combines efficient compression with support for transparency.

For example, an online shop may use transparent product images on different page backgrounds. A smaller AVIF file can help reduce the amount of data the page needs to download.

However, website owners should consider visitors using older browsers.

A practical solution is to provide an AVIF image with a PNG or WebP fallback. This allows browsers that cannot display AVIF to use another supported format.

Frequently Asked Questions

1. Can AVIF Have a Transparent Background?

Yes. AVIF supports an alpha channel, which allows images to have fully or partly transparent areas. A suitable converter can keep that transparency when changing PNG to AVIF.

2. How Do I Convert PNG to AVIF Without Losing Transparency?

Start with a PNG that already has a clear background. Use a converter that supports transparency, convert the image, and then check the result on both light and dark backgrounds.

3. Does Converting PNG to AVIF Reduce Image Quality?

It depends on the conversion settings. Lossy AVIF compression can remove some image details, while lossless AVIF can preserve pixel data. Higher-quality settings often produce better-looking results.

4. Can I Convert Transparent PNG to AVIF Online?

Yes. You can use an online PNG to AVIF converter without installing a separate image-editing program. Make sure the service supports transparent images and inspect the converted file afterward.

5. Why Does My Transparent PNG Become White After Conversion?

The original image may have a white background, or the converter may have removed its transparency information. Check the source PNG and use a converter that supports alpha channels.

6. Is AVIF Better Than PNG for Websites?

AVIF often creates smaller image files, which can help reduce download size. PNG remains useful for original graphics, exact pixel details, and compatibility with older software.

7. Can I Convert AVIF Back to PNG?

Yes. You can convert an AVIF image back to PNG using a compatible converter. However, converting it back will not restore details already removed by lossy compression.

Final Thoughts

Converting PNG to AVIF is a useful way to reduce image file size while keeping a transparent background.
