M4R to AVI Conversion FAQ
How do I convert M4R to AVI?
+
Drop your M4R file onto the upload box (or click to browse), wait a few seconds while PDF.to converts it, and download the resulting AVI file. No account, plugin, or install required.
Is the M4R to AVI converter free?
+
Yes. Basic M4R to AVI conversions are free for everyone on PDF.to. Paid plans unlock larger files, batch jobs, and priority processing.
Will I lose quality going from M4R to AVI?
+
Quality depends on the format pair. We use the best available encoder for AVI and pass through metadata when the target format supports it. For lossy targets, our defaults aim for the smallest noticeable difference.
What is the maximum M4R file size I can convert?
+
Free users can convert M4R files up to 100 MB. PRO subscribers can convert files up to 5 GB and run batches in parallel.
Can I batch-convert multiple M4R files to AVI?
+
Yes — drag any number of M4R files onto the page at once. Free accounts process them sequentially; PRO accounts process them in parallel for faster results.
Does PDF.to keep my M4R files?
+
No. Your M4R uploads and the resulting AVI files are deleted from our servers within an hour of the job finishing. We do not read, index, or share their contents.
Does the M4R to AVI converter work on mobile?
+
Yes. The whole interface is mobile-responsive and conversions run server-side, so your phone or tablet does not need processing power — just a browser.
Do I need to install anything to convert M4R to AVI?
+
No. Everything happens in your browser. There is nothing to download, install, or update, and no extension to grant permissions to.
How long does a M4R to AVI conversion take?

Most M4R files convert to AVI within a few seconds. Large or complex files (high-resolution video, multi-page documents, many pages) may take up to a minute.
Can I convert M4R to AVI without an account?

Yes. You can convert M4R files to AVI anonymously. Creating a free account just adds conversion history and a larger daily quota.
Which browsers does the M4R to AVI converter support?

All modern browsers — Chrome, Firefox, Safari, Edge, and Brave. Internet Explorer is not supported. Mobile Safari and Chrome on Android both work.
What if my AVI download does not start automatically?
