LAS Converter is an all-in-one media app made by LAS G Concept. It works in a web browser at lasconverter.lasgconcept.com and as a Windows app and an Android app. It converts video, audio and images, downloads public Facebook videos, turns speech into text in English, Nigerian Pidgin, Yoruba and Hausa, and makes subtitles. This page describes what each part does and what the limits are, so you can decide whether it suits you before you sign up.
What LAS Converter can do
- Video to MP3 and other audio formats. Pick a video (for example a sermon, lecture or recorded call) and extract the sound. Output formats include MP3, FLAC, WAV, M4A, OGG and OPUS. For MP3 you choose a bitrate of 128, 192, 256 or 320 kbps and a channel layout of Original, Stereo or Mono. Mono is a good choice for a single speaker, because the file is about half the size.
- Video compression and conversion. Shrink a video so it sends quickly on WhatsApp, or convert it to H.264 MP4 for wide compatibility.
- Image conversion. Convert PNG, WebP and HEIC photos to JPG, choose a quality level and resize.
- Facebook video downloader. Paste the link to a public Facebook video or reel and pick a quality. Private videos cannot be downloaded.
- Speech to text. Turn audio into text in English, Pidgin, Yoruba or Hausa and export TXT, SRT or VTT.
- Subtitles. Generate subtitles from the speech in a video and export SRT, VTT or ASS files, add a soft subtitle track or burn captions into the picture.
Your files stay on your device for conversions
The most important design decision in LAS Converter is where the work happens. Conversions of video, audio and images run inside your own browser using ffmpeg.wasm, a build of the open-source ffmpeg tool that runs in the browser. That means your file is not uploaded to LAS Converter's server for those conversions. Practical effects: private recordings stay private, and once the page has loaded the conversion works even on a slow connection.
Downloads from links are different. A Facebook download has to be fetched from Facebook by a server, so those requests do go through the LAS Converter server. The server sleeps when nobody is using it, which is why the first download after a quiet period can take about a minute to start.

Premium is prepaid and does not renew automatically, so you are never charged without doing it yourself. Prices are in naira; the app is built in Nigeria and focuses on payment methods Nigerians use. These limits can change, so the current free-vs-Premium page on the Converter site is the source of truth.
Web, Windows and Android
The same account works on the website, the Windows app and the Android app, but you can be signed in on one device at a time. The Windows app has two things the website does not: it can download from YouTube, because it downloads from your own connection (YouTube blocks servers), and it handles files larger than the 500 MB website limit. Our guide LAS Converter on the web, Windows and Android compares the three in detail.
Learn how to use it
The Converter site has step-by-step guides written against what the app really does: convert MP4 to MP3, compress a video for WhatsApp, convert HEIC or PNG to JPG, download a public Facebook video, transcribe Yoruba, Hausa and Pidgin audio and make SRT or VTT subtitles. For the thinking around the product, read Why we built LAS Converter and How to convert video to MP3 safely.
Responsible use
LAS Converter is a tool. You are responsible for having the right to convert or download what you put into it. Do not use it to copy material you do not own or have permission to use, and respect the terms of the platforms you download from. Our disclaimer explains this in more detail.
