PBM to AVIF Converter

Convert PBM files to AVIF. Batch, free and without uploading.

This tool converts PBM files to AVIF. Portable bitmap.

AVIF is a next-generation image format based on AV1 video coding. It usually beats even WEBP on size, but older programs may not open it. AVIF is lossy, and you choose the quality with the slider. For photos, 80–90% makes the file much smaller with a loss you won’t notice.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your PBM files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Set the quality and, if you like, a maximum size.
3. Press "Convert" and download the AVIF files one by one or as a ZIP.

Frequently asked questions

Will converting to AVIF reduce quality?

AVIF is lossy, but at 85–90% quality the difference isn’t visible. Lower quality means a smaller file.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your PBM files are converted to AVIF inside your browser and never sent to a server.
