Turn Blu-ray subtitles into editable SRT
If you have ever ripped a Blu-ray and wanted to edit, translate, or re-time the subtitles, you have probably hit a wall: the subtitles are not text. They are PGS tracks — tiny images of each line, baked frame by frame into the disc. A text editor can’t touch them, and most tools just pass them through unchanged.
PGSExtract solves this by reading those images and recognising the text on each one, giving you a standard SRT file you can edit anywhere.
How it works
- Your video stays on your machine. PGSExtract reads your MKV in the browser and pulls out just the subtitle stream — your video is never uploaded.
- OCR reads each frame. The image of each subtitle line is recognised in the language you choose, from a set of over a hundred.
- You get an SRT. The recognised lines are written out with their original cue timings, ready to download and edit.
You only pay for what you convert — one credit per subtitle frame, charged only when a job succeeds. Every track can run a free 100-frame preview first, with no account required, so you can check the quality before spending anything.
Already have text subtitles? They’re free
Not every subtitle track is an image. Many MKVs also carry text subtitles — SRT, ASS/SSA, or WebVTT. PGSExtract detects those and lets you download them straight from your browser, with no OCR, no account, and no credits. OCR is only needed when the track is image-based.
