How to convert Blu-ray, DVD, video & audio

Use a preset or control every detail

LosslessConverter handles common and specialized video and audio formats. For a quick job, choose a format or device preset. For precise output, customize the codec, sampling rate, bit depth, resolution, frame rate, bitrate, quality, and encoding options.

The same workflow can prepare a video for editing, make a file play on a specific device, remove the visual track to save audio only, or convert an entire batch in one run.

Convert Blu-ray/DVD to video

Use a compatible optical drive for a physical Blu-ray or DVD. You can also import a Blu-ray ISO image, a DVD ISO image or IFO file, or a BDMV/VIDEO_TS folder without an optical drive.

1. Open LosslessConverter. If you are using a physical disc, insert it in a compatible drive.
2. Click Add Disc in the main window. Select a Blu-ray or DVD, a Blu-ray/DVD ISO image (.iso), or a DVD IFO file (.ifo) to import.
3. Select the titles you want to convert, then choose MP4 or MKV from Output Format.
4. Review the audio tracks and subtitles, then choose an Output Folder.
5. Click Convert for one item or Start All for the queue. When processing finishes, open the output folder and check the video.

For output settings and troubleshooting, see the DVD and Blu-ray ripping guide.

Back up Blu-ray/DVD

Use Full Disc Backup for a 1:1 backup of the complete disc to an ISO image or disc folder. Use Lossless Copy to back up only the titles you select.

1. Open LosslessConverter and use Add Disc to import the Blu-ray or DVD source.
2. Open Output Format and select the Lossless group.
3. For a complete 1:1 backup, choose Full Disc Backup and select ISO or folder output. To copy only selected titles, choose Lossless Copy and select the titles to keep.
4. Choose an Output Folder with enough free space for the backup.
5. Click Convert for one item or Start All for the queue. When processing finishes, open the output folder and check the backup.

Extract subtitles from Blu-ray/DVD

Export subtitle tracks from a Blu-ray or DVD to separate subtitle files.

1. Open LosslessConverter and use Add Disc to import the Blu-ray or DVD source.
2. Open Output Format and select the Lossless group.
3. Choose Extract Subtitles.
4. Select the titles and subtitle tracks you want to extract, then choose an Output Folder.
5. Click Convert for one item or Start All for the queue. When processing finishes, open the output folder to find the subtitle files.

Convert a video to another format

This example converts an MP4 source to MKV. The steps are the same for combinations such as MKV to MP4, MOV to AVI, or WebM to MP4.

Can I convert video without losing quality?

Video quality can stay unchanged when the existing video stream is copied without re-encoding. MP4 and MKV are containers, so selecting MKV or changing a file extension does not guarantee a lossless conversion. Re-encoding can change picture quality. To avoid it, you need a compatible copy or remux mode (changing the container without re-encoding), when available for your source streams and output container.

Keep the original and test a representative clip before converting a full batch. Check the output codec, resolution and frame rate, compare picture quality, and confirm that the required audio tracks and subtitles are present and work in your intended player or editor.

1. Open LosslessConverter. The conversion workspace opens automatically.
2. Drag the source file into the window, or use Add Files or Add Folder.
3. Open Output Format and choose MKV.
4. Select Convert for one item or Start All for the full queue.

Extract audio from a video

1. Open LosslessConverter and add one or more video files.
2. Open Output Format, switch to Audio, and choose MP3, AAC, OGG, FLAC, WAV, PCM, or another supported format.
3. Select Convert or Start All.

Convert video for a phone, tablet, TV, or console

Device profiles select compatible settings for common Apple, Huawei, Samsung, Google, Lenovo, Microsoft, Sony, Android, TV, and console families.

1. Open LosslessConverter and add the source file.
2. Open Output Format, choose Device, and select the intended device or family.
3. Select Convert or Start All.

Prepare video for a website

Ready-made profiles help produce compatible output for YouTube, Facebook, Vimeo, TikTok, and other common platforms.

1. Open LosslessConverter and add the source file.
2. Open Output Format, choose Web Video, and select the destination website.
3. Convert the file, then upload the finished output through the platform itself.

Convert an audio file

Choose the output based on your priorities: MP3 offers broad compatibility and compact files; M4A/AAC is efficient and common on Apple devices; FLAC preserves audio losslessly; WAV is uncompressed and useful in production; OGG is an open format used by many games and web projects.

1. Open LosslessConverter and add the source audio.
2. Open Output Format, choose Audio, and select the target format.
3. Adjust sample rate, bitrate, or channels if needed, then select Convert or Start All.

Change video resolution

To use a preset resolution, add the video, open Output Format, choose a video format, and select the required resolution. To enter a custom value, choose the settings icon beside Output Format, open the Resolution menu, select Custom, enter the dimensions, and confirm.

To downscale for a smaller screen or file, follow the same steps and choose a lower output resolution such as 1080p, 720p, or 480p.
