Use MKVCleaver to Extract PGS and SUP Subtitles from MKV
What MKVCleaver Does
MKVCleaver is a Windows GUI frontend for MKVToolNix's mkvextract tool, designed specifically for extracting tracks from MKV files. It provides a simpler interface than the full MKVToolNix GUI for users who only need to extract subtitle, audio, or video tracks.
Open MKVCleaver and add your MKV file. PGS subtitle tracks appear in the track list labeled as "PGS" or "S_HDMV/PGS". Check the PGS/SUP track to extract, set an output folder, and click Extract. MKVCleaver calls mkvextract internally and saves the result as a .sup file.
MKVCleaver Requires MKVToolNix Installed
MKVCleaver is a wrapper — it provides the interface but calls mkvextract.exe from a MKVToolNix installation to perform the actual extraction. Install MKVToolNix first, then MKVCleaver will locate the required executable automatically.
MKVCleaver is Windows-only. Mac and Linux users should use MKVToolNix GUI directly, which is available natively on all three platforms.

Upload the Extracted .sup File Here
After MKVCleaver extracts the PGS stream as a .sup file, upload it to this browser converter. Select the subtitle language matching the PGS track — check the MKV's language tags in MKVCleaver if unsure. Select the OCR profile (Balanced works for most Blu-ray files), and click Convert.
The browser reads the PGS image data, applies Tesseract OCR, and produces an SRT file with timing identical to the original PGS stream. Download and use the SRT file with any media player or subtitle editor.
MKVCleaver vs MKVToolNix for PGS Extraction
MKVCleaver has a simpler interface focused on extraction. MKVToolNix GUI does more — it can merge, split, and modify MKV files as well as extract tracks, and it is cross-platform. For extraction-only workflows on Windows, either tool works equally well for pulling out PGS/SUP subtitle streams.

Frequently Asked Questions
Is MKVCleaver free to use for extracting PGS and SUP files?
Yes. MKVCleaver is free. It requires MKVToolNix to be installed separately, as it uses mkvextract.exe from that package.
Does MKVCleaver work on Mac or Linux?
No. MKVCleaver is Windows-only. Mac and Linux users should use MKVToolNix GUI directly — it provides the same PGS/SUP extraction capability natively on all platforms.
After extracting with MKVCleaver, how do I convert the SUP file to SRT?
Upload the .sup file extracted by MKVCleaver to this browser converter. Select the subtitle language, click Convert, and download the SRT file. No additional software needed for the OCR step.
Why does MKVCleaver need MKVToolNix installed?
MKVCleaver is a GUI wrapper — it provides the interface but calls mkvextract.exe from MKVToolNix to do the actual extraction work. Install MKVToolNix first, then MKVCleaver will find the required executable automatically.
Can MKVCleaver extract multiple PGS/SUP tracks from one MKV at once?
Yes. Check multiple subtitle tracks in the MKVCleaver track list and click Extract. Each selected PGS/SUP track is extracted as a separate numbered .sup file.
