Converting PNG to AVIF is one of the fastest ways to shrink image file sizes without visible quality loss. AVIF typically delivers 50–70% smaller files compared to PNG, which makes pages load faster and storage go further.
The free PNG to AVIF converter on WildandFreeTools works entirely in your browser. Your files never leave your device — nothing gets uploaded to any server. Drop in a PNG, adjust the quality slider if needed, and download your AVIF file in seconds.
What Is AVIF and Why Convert PNG to It?
AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media. It uses the AV1 video codec to compress images with remarkable efficiency — far better than PNG, JPG, or even WebP.
| Format | Typical file size (same image) | Transparency | Browser support |
|---|---|---|---|
| PNG | Large (lossless) | Yes | All browsers |
| JPG | Medium | No | All browsers |
| WebP | Small | Yes | All modern |
| AVIF | Smallest | Yes | Chrome, Firefox, Edge, Safari 16+ |
PNG is lossless by nature, which makes it large. Converting to AVIF applies modern compression that achieves similar or better visual quality at a fraction of the file size. For websites, this means faster page loads and better Core Web Vitals scores.
Step-by-Step: Convert PNG to AVIF
- Open the tool — no sign-up or install required.
- Add your files — click to browse or drag and drop one or more PNG files onto the upload area.
- Set quality — the default of 50 works well for most images. Move the slider right for higher quality (and larger files), left for more compression.
- Convert — the tool processes each file locally in your browser.
- Download — click the download button for individual files, or use Download All to get a ZIP containing all converted AVIFs.
The whole process typically takes under 5 seconds per image. For a batch of 20 PNGs, expect around 30–60 seconds total depending on file sizes and your device.

The quality slider controls the tradeoff between file size and visual fidelity. Here are practical starting points:
- Quality 30–50 — maximum compression. Good for thumbnails, background images, or photos where pixel-perfect accuracy isn't critical. Files will be noticeably smaller.
- Quality 60–75 — balanced. Most viewers won't see a difference from the original. This is the sweet spot for web images, blog photos, and product thumbnails.
- Quality 80–90 — high fidelity. For images where detail matters — portfolio work, product close-ups, infographics with fine text.
- Quality 90–100 — near-lossless. Rarely needed for web use; produces larger files that approach PNG in size.
A good workflow: start at 60, zoom into a detail-heavy area of the preview, then decide if you can go lower.
What Happens to PNG Transparency in AVIF?
AVIF fully supports alpha channel transparency — the same transparency that PNG uses. When you convert a PNG with a transparent background, the AVIF output will preserve every transparent and semi-transparent pixel exactly.
This makes AVIF suitable for:
- Logos on colored backgrounds
- Product images with cut-out backgrounds
- Icons and UI elements with soft edges
- Stickers or overlay graphics
Unlike JPG (which destroys transparency), AVIF handles it natively. You get the compression benefits without giving up the clean edges.
When to Keep PNG Instead of Converting
AVIF is not always the right output. Keep PNG when:
- You need maximum browser compatibility — older browsers (IE 11, older Safari) don't support AVIF. For broad compatibility, PNG or WebP are safer.
- The file is used in desktop software — print tools, photo editors, and design software often expect PNG or JPG, not AVIF.
- You're sending to someone who needs to edit the file — AVIF support in editing software is still growing. PNG is more universally editable.
- The image is already tiny — small icons under 5 KB won't see meaningful savings from conversion.
For modern websites, web apps, and anywhere Chrome or Firefox will render the image, AVIF is the better choice.

Open Free PNG to AVIF ConverterFrequently Asked Questions
Is PNG to AVIF conversion lossless?
At quality 100, conversion is very close to lossless. At default quality (50), there is minor lossy compression applied — but at normal viewing sizes, the difference is rarely visible. Zoom in to fine details or gradients if you need to compare closely.
Can I convert PNG to AVIF in bulk?
Yes. Drop multiple PNG files onto the tool at once. Each one is converted, and you can download them all as a ZIP file with a single click.
Does converting PNG to AVIF change the dimensions?
No. The converter preserves the original pixel dimensions. A 1200x900 PNG will produce a 1200x900 AVIF. Only the file format and compression change.
Will AVIF files display on iPhones?
Yes. Safari on iOS 16 and later (iPhone 8 and newer running iOS 16+) supports AVIF natively. For older devices, serve a JPG or PNG fallback using an HTML picture element.
