   Convert and download

   Run the queue and download the AVIF files individually or together as a ZIP.

Portable Network Graphics vs AV1 Image File Format

Why convert PNG to AVIF?

• The output can be optimized for a different balance of file size, transparency, and visual fidelity.
• AVIF may be the better handoff format for a design tool or publishing workflow.
• The converted copy can be tested in the destination app before the source archive is changed.
• Converting PNG to AVIF can make a photo or graphic work in software that does not accept the source format.

Will quality change?

The AVIF encoder is lossy. Fine text, sharp edges, and subtle gradients are the first places to check after conversion. Check a sample before processing a large batch.

Processing and limits

Processing

Server-side

Engine

Sharp and ImageMagick

Maximum size

100 MB per file on the server.

Batch support

Yes, multiple files can be queued; completed results can be downloaded as a ZIP.

Quality controls

Options can adjust output dimensions.

The file is processed on the server because the conversion requires a server-side engine or a utility operation.

• Photographic images are usually much larger than JPEG or WebP; metadata and animation support vary by viewer.
• Check metadata, dimensions, and compatibility after the conversion.
• Very large files can hit the 100 MB server limit before conversion starts.

Platform compatibility

The output is a AVIF file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.

When not to convert

• Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
• If the file contains sensitive data, review the processing model before uploading it to a server.
• Do not convert when the original PNG must remain the only editable or archival copy.

Frequently asked questions

Can I convert PNG to AVIF without installing software?

Upload a PNG file, choose the available AVIF options, run the conversion, and download the result. The tool is free, supports batches, and accepts server uploads up to 100 MB.

What does Convert PNG to AVIF cost?

It is free, requires no account, and adds no watermark. Server uploads are limited to 100 MB per file, and browser-first paths are limited by device memory.

Will quality change?

The AVIF encoder is lossy. Fine text, sharp edges, and subtle gradients are the first places to check after conversion. Check a sample before processing a large batch.

Does the file leave my device?

Yes. This conversion uses a server-side engine, so the file is uploaded over HTTPS, processed in an isolated request, and removed after the result is produced.

Can I convert several files at once?

Queue multiple files, run them together, and download the finished results as a ZIP. Each server file is limited to 100 MB, and large batches may take longer.

What should I check before using the output?

Open the downloaded AVIF file in the application or database you plan to use, check the structure against the source, and keep the original until the output is approved.
