What are the file size and length limits for Remove Vocals?

Remove Vocals (remove-vocals.com) accepts MP3 and WAV files up to 80MB and 10 minutes long. Both limits apply at the same time, so a file must satisfy each one to be processed. The site states the caps exist to avoid saturating its server.

The limits at a glance

Why the limits exist

The site explains that the 10-minute and 80MB ceilings are "necessary, so as not to saturate our server." In other words, they are capacity controls rather than format restrictions — the tool itself is built on the open-source Spleeter library and is designed to handle mixed instrumental-and-vocal tracks.

What happens if your file exceeds a limit

The page does not describe a specific error message for oversized or overlong files. What it does make clear is the workflow: you upload a song, you are redirected to a download page, and once processing finishes you click the download button to get the instrumental. If your file is over either cap, it falls outside the stated supported range, so the practical step is to shorten or compress it before uploading.

How to bring a file within the limits

• Trim the length: cut the track to 10 minutes or less in any audio editor before uploading.
• Reduce the size: for a long WAV file, exporting to MP3 usually brings it well under 80MB. A WAV at 10 minutes can easily exceed the size cap depending on sample rate and bit depth, while the same audio as MP3 is far smaller.
• Check both, not just one: a short file can still be too large (high-bitrate WAV), and a small file can still be too long (low-bitrate MP3). Confirm both numbers.

Other things worth knowing before you upload

• Daily free allowance: the service is free for up to 2 songs per day. If you need more than that in a day, plan around the reset rather than expecting unlimited runs.
• No software or account: you do not need to install anything or register to use it.
• Vocals-only output: if you want the isolated vocal track instead of the instrumental, the page points to a separate tool, acapella-extractor.
• Examples available: the site has an examples section where you can hear isolated instrumentals before committing your own file.

If your song is under 10 minutes and under 80MB in MP3 or WAV, it fits the supported range and you can upload it directly. If it exceeds either limit, edit it down first — the caps are hard requirements, not suggestions.
