How it works

1

Paste the link

Or switch to the Convert my file tab and upload a file from your computer.

2

Pick the format

Each option says what it produces: MP3 320 kbps (audio), MP4 1080p (video), SRT (subtitles) or JPG (thumbnail).

3

Download

The bar shows the progress. When it finishes, the download button appears.

What each format is for

If you only want the music, pick an audio format. If you want to watch it later, pick video. Subtitles and thumbnails come as separate files.

Audio

FormatWhat it is forAverage size
per minute
MP3 128 kbps Basic quality. Good for speech, podcasts and lectures. Plays on any device. ~1 MB
MP3 192 kbps The best balance for music. This is what most people should choose. ~1,4 MB
MP3 320 kbps The most MP3 can offer. Only worth it if the source is already high quality. ~2,4 MB
M4A / AAC Same quality as MP3 in less space. Ideal for iPhone and iPad. ~1 a 1,4 MB
WAV Uncompressed, for audio editing. Huge files, so it is limited to 10 minutes. ~10 MB

Video

FormatWhat it is forAverage size
per minute
Best quality Takes the highest resolution available in the original video. Use it when in doubt. varies
MP4 480p Light, for phones and slow connections. Simple image, small file. ~9 MB
MP4 720p HD. Sharp on phones and laptops without getting heavy. ~20 MB
MP4 1080p Full HD. Best choice for watching on a TV or large screen. ~35 MB
WebM Compresses better than MP4, but takes far longer to process and not every device plays it. Prefer MP4 if unsure. ~14 MB

Subtitles and thumbnail

FormatWhat it is forAverage size
SRT A plain text subtitle file. Put it in the same folder as the video, with the same name, and the player loads it automatically. a few KB
JPG The video cover image at full size. Handy for thumbnails and playlist covers. ~100 KB

Sizes are estimates: the real value depends on the video. Content with a lot of motion takes more space than a person talking to the camera.

Quick questions

Download from a link

Paste the address and choose what you want: the full video (with audio), MP3, subtitles or thumbnail. The file is delivered as it is at the source, with no re-encoding, so it is faster and loses no quality.

Converting my own file

Use this when you already have the file and want another format: MP4 to MP3, WAV to MP3, a large video down to 720p. This one does re-encode, which is why it takes longer.

Why 320 kbps is not always worth it

Video services deliver audio that is already compressed, usually between 128 and 160 kbps. Converting that to 320 recovers no quality at all; it only makes the file bigger. MP3 192 is usually the best balance.

Automatic subtitles

When the video has no subtitles uploaded by the author, the system falls back to the platform's automatic transcript. It makes plenty of mistakes, especially with proper names.

Are the files kept?

No. The download link expires after 30 minutes and the file is deleted from disk. After that you have to download it again.
