# Uploading files

> Supported formats, size limits, and how new files find their song.

Source: https://docs.wavdrop.link/uploading

Drop files onto a project, or click the upload area to browse. Several files at once is fine.

## Supported files

| Type | Extensions |
| --- | --- |
| Lossless audio | .wav, .aiff, .aif, .flac |
| Compressed audio | .mp3, .m4a, .mp4, .aac |
| Archives (for stems or extras) | .zip |

WAVDROP keeps your original file exactly as you uploaded it, and checks that each file really is the type its name says.

## Size limits

| Plan | Largest single file | Total storage |
| --- | --- | --- |
| Free | 100 MB | 1 GB |
| Plus | 3 GB | 500 GB |
| Pro | 3 GB | 1 TB |

Your current usage is in **Settings**, under **Plan & storage**.

## New version or new song?

When a file's name matches a song already in the project, or comes close, WAVDROP opens **Review uploads** before anything lands:

- **Stack as a new version** puts the file under that song as its newest version.
- **Keep separate** adds it as its own song.

Files that don't resemble any song upload straight away as new songs. If you guessed wrong, you can fix it later: see [Versions](https://docs.wavdrop.link/versions).

## Clean names

Turn on **Auto-name tracks** in **Settings** to drop a leading track number like "03 - " from new uploads. The extension stays, and songs you've already uploaded aren't changed.

## While it uploads

Uploads run in your browser, so keep the tab open until they finish. If your connection drops, WAVDROP tells you and you can try again.

> [!NOTE]
> Hit a limit? The message tells you which one: the file is over your plan's upload size, or the workspace is out of storage. Delete old files or move to a bigger plan, then upload again.
