How to convert PNG to AVIF online
- Select a supported PNG file from your device and check its detected type and size.
- Open Settings for the selected file to review image quality. Leave the displayed defaults if they match your needs.
- Choose Convert and wait for the result. A queued job is waiting for a processing slot; a processing job is being handled.
- Download the result and open it in the application where you will use it. Keep the original and remove the server copy when finished.
What you will download
One still AVIF image. The first frame or TIFF page is used; source metadata is removed.
Available settings
- Image quality
- 40–95; default 85. Higher quality usually creates a larger file.
Understand your file formats
- PNG is a lossless format useful for screenshots, diagrams and transparent artwork.
- AVIF is an image format often used to keep detailed web images compact.
PNG vs AVIF: what changes?
- Use PNG when lossless pixels, screenshots, interface graphics or supported transparency matter more than the smallest possible file.
- Use AVIF for compatible web publishing workflows where compact modern image delivery matters and older application support is not required.
Technical format comparison: PNG vs AVIF
These properties describe the formats and the behavior implemented by this route. They are a decision aid, not a promise that two applications render every file identically.
| Format or operation | Format category | Compression behavior | Transparency support | Multi-page or animation behavior in ConverterZap | Typical best use |
|---|---|---|---|---|---|
| PNG | Raster image | Lossless DEFLATE compression | Yes; supported alpha is kept except when output is flattened to PDF/JPEG | Still image; the first frame is used | Use PNG when lossless pixels, screenshots, interface graphics or supported transparency matter more than the smallest possible file. |
| AVIF | Raster image | Lossy AV1 image compression | Yes for supported still output | Still image; first frame/page is used | Use AVIF for compatible web publishing workflows where compact modern image delivery matters and older application support is not required. |

About your output
PNG preserves pixel detail but photographs can produce large files. AVIF support depends on the application opening the image; encoding can take longer. Up to 24 megapixels. The first frame/page is used. EXIF orientation is applied; metadata is removed. JPEG has a white background. HDR and wide-gamut colors are converted to 8-bit RGB; color appearance may change.
Questions about PNG to AVIF
Is AVIF always the best output for a PNG screenshot?
No. A compact AVIF can be useful, but lossy encoding can affect small lettering and sharp edges. Compare the result with your PNG at its intended display size.
What format detail changes from PNG to AVIF?
PNG uses Lossless DEFLATE compression; AVIF uses Lossy AV1 image compression. The conversion writes a new encoded file, so compare transparency, color and file size in the destination workflow.
Which real-world check matters before I share this AVIF file?
Open the downloaded result in the application that will receive it and check the behavior described in the limits: Up to 24 megapixels. The first frame/page is used. EXIF orientation is applied; metadata is removed. JPEG has a white background. HDR and wide-gamut colors are converted to 8-bit RGB; color appearance may change.
