Free online converter for bidirectional PNG and AVIF format conversion. Significantly reduce image file sizes while maintaining high quality.
Choose filesDrop or click to upload PNG / AVIF images
Image (Supported formats: .avif, .png)
Max 1 MB • Max 5 files
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Add PNG or AVIF image files and the conversion direction is chosen from each file’s input format: PNG is exported as AVIF, while AVIF is exported as PNG. You can add up to five images in a batch, with a maximum input size of 1 MiB per file. Each completed item can be downloaded separately.
AVIF is an image file format associated with AV1 image coding. A format change re-encodes the image; it does not guarantee a smaller file or restore detail that was lost in an earlier lossy encode. This page exports a still image from the loaded image and does not promise to preserve an animation sequence. Output dimensions follow the loaded image; there are no crop, resize, or quality controls.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Select or drag in PNG and/or AVIF files. Keep each file at or below 1 MiB and the batch at five files or fewer.
Check the direction shown for each item. A PNG targets AVIF; an AVIF targets PNG. Conversion starts automatically after files are added.
When an item finishes, download it from its row. The output keeps the original filename and uses the new format extension.
Open the result and compare its appearance and file size with the source before using it in a site or document.
Use cases
See how the tool fits into real work and everyday tasks.
Convert a PNG asset to AVIF, then check the resulting file size and appearance. Confirm that the site, publishing pipeline, and target audience’s viewing software can handle AVIF before replacing an existing asset.
If a document or image workflow accepts PNG more reliably, convert an AVIF to PNG and inspect the exported pixels. PNG output does not recover information discarded when the AVIF was encoded.
Q&A
Find concise answers to common questions and confusing cases.
No. The result depends on the image and the browser’s encoder. Compare the actual file sizes; the format name alone does not establish a size saving.
No. The page does not offer a quality slider, crop, or resize setting. It exports at the loaded image dimensions using the browser’s available encoding behavior.
Animation preservation is not provided. Treat the output as a still image and verify it before replacing an animated source.
Image decoding and AVIF encoding depend on the browser’s support. If the requested format is unavailable, browser canvas export can fall back to PNG. Check the downloaded file in an image viewer and try a browser that supports AVIF encoding.
Notes
Review scope, result limitations, and important precautions before use.
Conversion is a re-encoding step, not a lossless restoration process. Transparency may be represented by both formats, but appearance can still vary with browser support and encoding. Keep the original file until you have checked the downloaded result in the software and browsers that matter to your workflow.
