Before you begin

Confirm the disc source and playback goal.

Select the correct title, audio, and subtitle tracks, then match the output to the player, device, or archive workflow.

Create a Blu-ray ISO directly

A Blu-ray ISO stores the disc file system in one image file, making the title easier to archive, mount, or move without handling a separate BDMV folder.

LosslessConverter can create the ISO from the loaded disc in one workflow. You need a readable Blu-ray drive and an output location with enough free space for the image.

Full disc, selected titles, or a video file?

Choose Full Disc Backup for the complete disc structure in an ISO or folder. Choose Lossless Copy when you only need selected titles; that is not a substitute for a complete disc archive. Converting a title to MP4 creates a separate playback file and does not retain the original disc menus or complete structure.

Verify the image in your intended player

Mounting an ISO successfully does not prove that a player supports Blu-ray navigation, menus, or every audio and subtitle format. Open the completed backup in the player you plan to use. Check the expected titles and chapters, menu navigation where supported, audio-language switching, subtitles, and playback at the beginning, middle, and end. Keep the original disc until these checks pass.

How Blu-ray protection is handled

Commercial Blu-ray discs can combine more than one protection layer. LosslessConverter handles supported protection while reading the disc, so ISO creation does not require a separate decrypt-to-folder stage first.

AACS encrypts the audio and video content stored on many commercial Blu-ray discs. A supported AACS source is decrypted as the disc is read.
BD+ adds a title-specific protection layer on top of the disc content. When the disc version is supported, it is removed in the same import process as AACS.
AACS Bus Encryption protects the data path between a compatible Blu-ray drive and the computer. When present and supported, this transfer-layer protection is removed during the same disc-reading process.
Region A, B, and C controls are playback restrictions rather than encryption algorithms. Supported region checks are removed while the disc is read, so the resulting ISO is not tied to the original region setting.

Cinavia is an audio watermark, not disc encryption. BD-J and BD-Live provide Java-based navigation or online features and are also not encryption systems. They should not be described as additional decryption stages.

Workflow direction

Recommended output

Use the output parameters required by this guide.

Only parameters stated by this workflow are shown. Match any remaining settings to the source and destination.

Format: Blu-ray ISO
Mode: Lossless
Protection handling: AACS / BD+ / Bus Encryption
A / B / C control: Region removed

Three-step workflow

Create and verify one test output before processing the full batch.

Add the disc

Load the Blu-ray disc

Insert the Blu-ray disc, open LosslessConverter, and select Add Disc. Supported AACS content encryption and BD+ protection are removed while the disc is read. AACS Bus Encryption is also removed when it is present on the drive-to-computer path, and region controls are handled in the same process. Confirm that the complete disc source is recognized before continuing.

Preserve the disc image

Choose Lossless > Full Disc Backup > Blu-ray ISO

Open Output Format, select the Lossless group, choose Full Disc Backup, then select Blu-ray ISO. This creates the ISO directly from the loaded disc, so a separate folder backup and a second ISO-building application are not required.

Blu-ray ISOSelect Lossless, choose Full Disc Backup, then select Blu-ray ISO.

Create the image

Select Start All to create the ISO

Choose an output folder with enough free space, then select Start All. When the task finishes, mount or open the ISO to confirm that the disc structure, menus, titles, audio tracks, and subtitles are available.
