Multiple files supported · Local conversionImages are converted locally in your browser. Source files and results are not uploaded to a conversion server.
Keep your existing workflow: choose files, wait for a preview, and download.
This PNG to AVIF converter reads images on your device. Selected files are not uploaded to a conversion server.
Transparent areas and soft shadows remain available when you place the result over a page background.
Select several assets together, then save individual results or download the completed set in a ZIP.
PNG to AVIF conversion and downloads require no account or paid plan. No site branding is added to the image.
The output keeps the decoded width and height. The converter does not resize or crop your artwork.
PNG to AVIF conversion starts automatically after file selection.
Select one or more .png files, or drag them into the upload area. Use the original image file, not its web address.
The converter reads the pixels and creates AVIF data. Processing time depends on image dimensions and your device.
Click a completed preview to download it. For a batch, wait for all required images to finish before choosing Download All AVIFs.
Compare pixel storage, transparency, and dimensions separately from file size.
| Property | AVIF output | PNG source |
|---|---|---|
| Compression | Lossy color encoding in this tool | Lossless pixel storage |
| Transparency | Existing alpha channel preserved | Supports an alpha channel |
| File size | May be smaller; compare the result | Can be large for complex images |
| Dimensions | Decoded width and height retained | Source width and height |
| Compatibility | Check your publishing platform | Widely supported in editors |
PNG to AVIF creates a newly encoded image, rather than changing the file extension.
PNG stores pixels without lossy compression. It is useful for screenshots, interface assets, and graphics that will be edited again.
AVIF supports transparency alongside efficient compression. This converter creates a static image using lossy color encoding; it does not preserve animated PNG sequences.
Use these checks to decide which files belong on your site.
PNG to AVIF does not always produce a smaller file. Compare the result card with the source file, particularly for small icons and flat-color graphics.
Place the image over the background used by your website. Check soft shadows and translucent edges that can be hard to judge on a white preview.
For screenshots and diagrams, inspect labels and fine lines at the size readers will see. Exact-pixel artwork may be better kept as PNG.
Upload one converted image to your content system first. A file extension change cannot make AVIF work in a system that requires another format.
Group assets by their purpose so each download is easy to put to work.
Use PNG to AVIF for isolated products that appear over several promotional backgrounds without baking the background into each image.
Collect desktop and mobile campaign artwork in one batch, then hand over the ZIP with the rest of the launch assets.
Keep a separate file for each illustrated step so a product update only requires replacing the screenshots that changed.
Keep matching base filenames for the editable PNGs and the AVIF web assets, making it easier to identify the same graphic across a project.
Practical answers about image quality, formats, and downloads.
No. This tool uses lossy color compression with alpha preserved separately. Equal image dimensions do not mean identical color pixels.
White pixels are not transparent pixels. If the PNG already has a solid background, that background remains. Remove it in an editor before converting if you need a cutout.
This converter currently uses a fixed quality setting. There is no manual quality slider or lossless mode.
This tool exports still images, not complete animation sequences. Use an animation converter when you need to retain motion.
Encoding has overhead. A tiny icon or simple graphic may already be stored more compactly as PNG, even when a more complex image would benefit from AVIF.
The remaining images continue processing. The ZIP contains successful results only; you can select a failed file again to retry it.
No. Results are held in the browser session. Download the files before clearing the results or closing the page.
