Small files, modest formats, low data use. Built for the phone you actually have.
Free · No signup · Works on mobile and desktop
U2Mate is a free browser-based converter built around a case most converter sites ignore: an older phone, limited storage, and a connection that is not fast or unlimited.
Most tools default to the highest quality they can offer, on the reasonable assumption that better is better. That assumption breaks down quickly if your device has 16 GB of storage, your data allowance is metered, or your phone is a few generations old and struggles with high-bitrate video. U2Mate defaults to 360p for exactly that reason — the higher options are there if you want them, but they are not the starting point.
File size scales sharply with quality, and the difference is much larger than people expect. For a five-minute video:
| Quality | Rough size | Videos per 1 GB |
|---|---|---|
| MP4 1080p | ~150 MB | about 6 |
| MP4 480p | ~50 MB | about 20 |
| MP4 360p (default) | ~30 MB | about 33 |
| MP4 240p | ~15 MB | about 66 |
| MP3 128kbps | ~5 MB | about 200 |
On a 5.5-inch phone screen, the visible difference between 360p and 1080p is far smaller than the five-fold difference in file size and data use. For anything where you are mainly listening — music, a lecture, a talk — the MP3 option is smaller again by an order of magnitude.

Playback happens locally in your browser — your file never leaves your device.
Five options, weighted towards the smaller end, with 360p preset as the default:
| Option | Best for |
|---|---|
| MP4 360p (default) | Everyday phone viewing on limited storage or data |
| MP4 480p | A little more detail, still a modest file |
| MP4 240p | Very tight storage, or a very slow connection |
| MP3 128kbps | Speech — lectures, podcasts, interviews |
| MP3 192kbps | Music, still a small file |
If you specifically want 1080p or 4K, one of the tools linked at the bottom of this page is a better fit — this one is deliberately weighted the other way.
Most failed downloads on mobile are not the converter's fault — they are interrupted transfers. A few things genuinely help.
Delete the partial file before retrying. Some browsers will otherwise resume into the same broken file, and the result never plays. Then try one quality step lower — the drop in visual quality is usually less noticeable than the improvement in reliability.
Compare the size against roughly what you expected from the table above. A file far smaller than expected is almost certainly incomplete. The player on this page is a quick way to confirm: if it plays through, the file is sound.
The genuine risks with converter sites follow a recognisable pattern: fake download buttons that install something other than your file, prompts to allow browser notifications, pages pushing a "required codec" or "player update," and download links that hand you an .exe when you asked for an .mp3. If a site does any of those, close the tab.
The built-in player reads files locally using an object URL. Nothing is uploaded to Softlookup or anywhere else, which is why it keeps working even if you go offline after the page loads.
This is not boilerplate. Downloading copyrighted material without permission is a violation in most countries regardless of the tool used. The legitimate uses are common though: your own uploads, lectures your institution has released, podcasts distributed for offline listening, and royalty-free media for projects.
U2Mate is a free browser-based converter focused on smaller files and low-bandwidth formats, aimed at older phones, limited storage and slow or metered connections.
Yes. Those are common ways people type the same thing, and all of them land on this page. There is no separate tool.
Because on a phone screen the visible difference is small, while the file is roughly five times smaller. If you want higher quality the option is there, but it is not the starting point.
It runs in the browser, so there is no app to install and no minimum Android or iOS version beyond having a modern browser. The smaller output formats also play more reliably on older hardware.
Usually interrupted transfer or full storage. Check your free space, choose a smaller option, stay on one network, and delete any partial file before retrying.
Only convert content you own, have permission to use, or that is freely available for download.
