Just enter the URL of your video in the input field. But you can also simply enter a search term. We show you hen directly to the results of the most visited video sharing sites. Then just click "Convert". You will then be redirected to the conversion page, where you can select the target format and the settings where you can optimize your video or your music file.

Once your file has been converted, you can conveniently request via the input form the download link. We will then send you a link via email.

2. If you are on the page "convert Youtube Video":

Simply type the URL of the video or music file, select the output format. Optionally you can still change settings for resolution, bit rate and other quality features.

You can upload at the same time up to 10 files. Now start the conversion.

An overview of the progress of your conversions can be found on the page "Your uploads (queue)"

Try also our music charts. Here you can find the top 50 from the USA, Germany and UK.

3. Explanation of advantages/disadvantages of the compression process":

The main aim of converting videos or music files into other formats is to compress the current file. There’s a wide range of video and audio formats available to do this. Each of these formats has individual properties, even though – due to the high level of development – they have little impact on playback.

4. The most important audio formats

MP3 - MPEG 1 audio layer 3

The MP3 audio format is the classic of the codecs with a standardised compression method. MP3 produces small files in very good quality. Data is compressed without noticeably compromising quality. One big advantage of the format: it’s compatible with all operating systems and suitable for playback on all mobile players. The MP3 codec is available as a licensed version or as an open source codec, LAME.

AAC - Advanced Audio Coding

This compression method for audio files developed by the Moving Picture Experts Group (MPEG) is a higher quality MP3 successor. The compression result using the AAC method is a small audio file with excellent sound quality. Apple particularly relies on this format, which, like all other popular audio formats, is one of the most lossy compression methods.

M4A - compressed audio file in MPEG 4 container format.

One of the main advantages of the M4A files is the lossless compression of an audio file, whereby the file is decoded with the original sound quality. The sound quality is correspondingly high with a low memory storage requirement. The disadvantage is that the format is only compatible with Apple devices.

FLAC - Free Lossless Audio Codec

This compression method is a free codec from the developer workshop of the Xiph. Org Foundation. The purpose of FLAC is the lossless decoding or coding of audio files and is rather like a ZIP file. FLAC can reduce an audio file by 30 to 60 percent of its original size. This codec is particularly recommended for use with complex music compositions such as classical music arrangements.

OGG - Ogg Vorbis

Like FLAC, OGG was also developed by the Xiph. Org Foundation and is available as a free codec. OGG is a lossy method of audio data compression and an alternative to the MP3 format with all its benefits.

WMA - Windows Media Audio

Compression using WMA is, like most audio formats, a lossy method and similar to the MP3 method. As part of the Windows media platform, the format is only compatible with a selection of audio programs. It is not compatible with Apple devices. The sound quality of a WMA file is on a par with MP3.

5. The most important audio video formats

MP4 - MPEG-4

Video files with the file extension *mp4 form part of the MPEG family. The impressive features of this innovative video format are its high flexibility and corresponding HD image quality. This format is used both on the Internet and on Blu-Ray or TV. The advantage of this format lies in its high quality during compression. However, this does result in corresponding computing intensity.

AVI - Audio Video Interleave

The AVI audio video format is one of the classics. It was developed by Microsoft as a rival product to QuickTime and is now standard for all Windows operating systems. The format was impressive from the outset with its outstanding image quality for large memory consumption, and today it offers small, high-quality files. It does lack a few important functions in terms of professional use, though. However, as a sole format for playback on different end devices, it’s a great alternative to other audio video formats.

WMV - Windows Media Video

WMV format also goes by the name ASF (Advanced System Format). It is available under the file extensions *wmv or *asf and is the successor to AVI. It features higher flexibility than its predecessor and is suitable for direct streaming – one reason why people mainly like to use it on the Internet. The disadvantage here though is that the format is not supported by all devices and programs developed by Microsoft.

3GP and FLV (Flash Video)

Adobe is the developer of this container format. FLV is preferable for use with YouTube and the Internet in general. In most cases, the sound and image quality is compromised during the lossy compression of video files, but the result still meets all the criteria required on YouTube. 3GP has been specially designed for use on tablets and smartphones and presents the same advantages and disadvantages as FLV. Because of its quality, it is only suitable for mobile end devices. The development of WebM and HTML5 has led to an apparent decline in the use of these two formats with a preference for new compression methods.
