AVConvert helps you convert your audio and video files much faster. You simply right-click the files in Windows Explorer and trigger the desired conversion in the cascaded context menu - it's that easy! Wait a few seconds and the processed files will be available in the source files' folder. AVConvert's options will be shown in the context menu when you right-click a media file. You'll find options to convert files to other media formats, to losslessly extract audio from video files or to resize selected videos. The animated gif shows some of the available context menu options (varying depending on the right-clicked media file type).

AVConvert is provided free of charge and will work on all versions of Windows. File conversion is extremely easy and super-fast and there's nothing for you to configure. Select one or more files of the same file type in Windows Explorer, right-click one of them and choose the desired option. The conversion process will take just a few seconds - even for lots of files (in case of audio conversion). Many conversion types are completely lossless because AVConvert will rather transcode the files instead of re-encoding them (for instance Wave to FLAC). Transcoding between such formats is lossless both ways! Lossless video editing is also possible which speeds up working with videos by magnitudes! During lossless video editing, processing speed is only limited by the read and write speed of the hard drive and not by the CPU! This is something almost never seen in other video editors. AVConvert comes with a settings template management that lets you easily switch between different sets of parameters.

AVConvert offers the following conversion and transcoding options (for one or multiple selected files of the same file type):

• conversion between the most common lossless audio formats (Wave, FLAC, WavPack, AIF, CAF) - even multichannel-capable!
• conversion from Wave to lossy formats (AC3, MP3, M4A, AIFF, CCITT a-law, CCITT mu-law and OPUS) and vice-versa. Metadata and tags will be kept whenever possible.
• lossless audio extraction from MKV, MP4, MPG, WebM and MOV video files (AC3, MP2, MP3, PCM/Wave, M4A and OPUS). If the video file contains a second audio stream, this one can also be extracted (even a 3rd and a 4th audio stream in an MP4 video file).
• lossless muxing of MKV, MOV, MP4 and WebM video with various audio streams (AAC, M4A, MP3, OPUS, WAV and WebM, depending in the resp. video format). You can choose to either add audio to a video file (no matter how many audio streams it already contains) or to replace all existing audio with the new audio. Video and audio file to be muxed need to have the same file names. Note: The muxing function will always be performed on ALL video files in the same folder (provided that identically labelled audio files are found) even if only not all video files had been selected via right-click menu.
• convert audio from MKV, MP4, MPG, WebM and MOV video files to Wave.
• merge-convert 2 audio streams from a single video file (MKV or MP4) into a single 4-channel Wave file.
• split single 4-channel Wave file into 2 stereo Wave files.
• merge-convert 3 audio streams from a single MKV video file into a single 6-channel Wave file.
• split single 6-channel Wave file into 3 stereo Wave files.
• convert between lossy and lossless multichannel audio formats (Wave, FLAC, WV, OPUS, M4A), retaining all audio channels.
• change bit depth of Wave files (16 to 24 bit and vice-versa).
• convert stereo Wave files to mono.
• convert mono Wave files to stereo.
• convert LR (left-right) stereo wave files to MS (mid-side) stereo (and vice-versa).
• convert sample rate of Wave, WavPack and FLAC files from 44.1 k to 48 k and vice-versa.
• extract left or right channel from Wave, MP3 or M4A files.
• losslessly transcode AAC files to M4A file and vice versa.
• quickly create a video from a single JPG image incl. a temporary insert image and/or a pernanent logo and an optional zooming effect into the still image incl. M4A, MP3 or OPUS audio with the length of the audio (in 720, 1080, 2k or 4k).
• quickly create JPG slideshow from all or selected JPG files in a folder (in 720, 1080, 2k or 4k).
• extract image sequences of user-definable sections of videos.
• quickly batch-watermark JPG images by adding a title insert and/or a logo to all currently selected JPG files in a folder.
• create a timelapse video from JPG images or a video that mimics a fast image browsing effect by setting the images per second for the video.
• convert animated GIFs to MKV video files.
• slowly zoom into MKV videos.
• overlay one video over another one.
• de-mux (de-interleave) video files into separate files for video and audio.
• create screen recording videos and let AVConvert include a pre-configured, temporary title insert image, a custom text insert and/or a permanent logo already while the screen is being recorded!
• reverse MKV videos (output video plays backwards).
• resize MOV, MP4 and MKV video files to 4k (MOV + MKV only), 2k, 1080p or 720p either with or without audio re-compression to AAC/M4A, preserving all audio streams of the original video.
• losslessly crop top and bottom of videos to achieve various wide, cinematic looks.
• losslessly crop video's width and/or height by any amount of pixels (divisible by 2). Unique feature: Previously cropped areas are not lost in the output video and, thus, can be losslessly restored in a later "un-cropping" process!
• cut/trim video footage either including an insert image, a title or text incl. a permanent custom logo at the same time.
• rotate video footage by 90, 180 or 270 degrees and/or flip it.
• if audio is not in sync with video, you can specify an audio offset value to re-synchronize the audio with the video.
• convert MKV, MOV and MP4 video files to MOV ProRes Proxy, LT, SQ, HQ or DNxHD. The audio of the source video will be converted to WAV.
• alternatively, convert/resize MKV, MOV or MP4 files to 4k, 2k, 1080p or 720p while simultaneously overlaying a PNG image/watermark or text and/or a permanent logo. During the same process, key frames will be inserted every 0.5 seconds plus also on every scene change and the original audio will be converted to AAC.
• Re-compression quality of AVConvert can be set to high quality or low quality for video conversions and audio independently.
• losslessly concatenate multiple video files with identical media file properties in only a few seconds.
• create super smooth slowmo videos (slowed down by factor 1.5, 2, 3 and 4) either with or without the simultaneous insertion a permanent custom logo.
• Speed-up or slow down videos losslessly by changing the frame rate to 23.976 fps, 24 fps, 25 fps, 29.97 fps, 30 fps or 50 fps (up to 100 fps for 25 fps footage). The resulting video might not play back fluently in every case. However, it helps to subsequently convert the videousing one of AVConvert's conversion options.
• create 4-channel true-stereo impulse response files from regular stereo WAV impulse response files for convolution reverb plugins (L-R channel layout converted to L-R-L-R channel layout or L-R-R-L channel layout).

AVConvert uses ffmpeg to do its magic. A help file is provided in the package but you can also download it here. The PDF file contains detailed instructions on how to install and uninstall AVConvert and also on how to use the tool.

In case a desired conversion option is not available for a specific file type, convert the file to Wave first and then to the desired format. In case the conversion process fails, you have probably tried to perform an unsupported conversion. Delete the resulting empty file and try another option instead. In order to reduce the risk of file name collision, file names of newly created files will automatically get suffices like "-16 bit", "-44.1k" or "-720p".

AVConvert does not require an install via setup routine. It's required to be extracted into "C:\AVConvert" (this path is hard-coded and therefore mandatory in order to make AVConvert usable on any localization worldwide). As soon as you double-click the provided "register AVConvert.bat" file, the context menu entries are added to the Windows registry and are immediately operational. Clicking a context menu entry will trigger a simple DOS batch file in the "BATS" subfolder containing the preconfigured conversion commands for ffmpeg. The utility can be entirely uninstalled anytime by double-clicking the provided "unregister AVConvert.bat" file and will leave no traces behind on your computer. After that, you can also safely deletethe entire AVConvert folder. Please see the help file for more information.
