Convert PGS and SUP Files Without Subtitle Edit
The Subtitle Edit Windows Limitation
Subtitle Edit is a Windows-only .NET application. Mac and Linux users cannot run it natively, which leaves a gap for PGS and SUP subtitle conversion on those platforms. This browser tool fills that gap directly — the same Tesseract OCR engine runs in your browser on any operating system.
For Windows users who want to avoid installation or need a quick single-file conversion, the browser tool is also a practical alternative. Open the page, upload your .sup file containing PGS data, convert, and download SRT — no software to install or update.
Same OCR Engine, Different Interface
Subtitle Edit calls the system-installed Tesseract binary for PGS and SUP OCR. This browser tool ships Tesseract compiled to WebAssembly. Both execute the same LSTM neural network models — quality differences come from workflow, not from the underlying OCR engine.
For typical high-quality Blu-ray PGS content, automated browser conversion and Subtitle Edit's manual frame-review workflow produce equivalent results. Subtitle Edit's manual review primarily helps with low-quality sources or stylized fonts where human correction catches more errors.
Subtitle Edit vs Browser Tool: Which to Use
Use the Browser Tool When
You are on Mac or Linux. You want instant results without any installation. You are converting high-quality Blu-ray PGS or SUP files where automated OCR accuracy is sufficient. You need a quick one-off conversion and don't want to maintain desktop subtitle software.
Use Subtitle Edit When
You are on Windows and need an integrated OCR plus editing workflow. You are processing low-quality PGS or SUP sources where frame-by-frame manual review significantly improves output quality. You need batch conversion via Subtitle Edit's command-line interface. You want to apply OCR correction dictionaries or custom word lists during conversion.

Frequently Asked Questions
Can I use this browser tool instead of Subtitle Edit on Mac?
Yes. The browser tool provides equivalent PGS and SUP OCR on macOS without any installation or Windows emulation. Upload your .sup file in Safari or Chrome and get SRT output.
Does Subtitle Edit's manual review significantly improve output quality for PGS files?
For high-quality Blu-ray PGS content, the difference is small. For low-quality sources or stylized fonts, manual review in Subtitle Edit catches more errors. For critical professional work, Subtitle Edit's review workflow is worth the extra time.
Do both tools support the same languages for PGS and SUP conversion?
Yes. Both access the same Tesseract language packs covering 40+ languages. This browser tool loads the selected language model on demand — no pre-download needed.
Can Subtitle Edit batch convert multiple SUP/PGS files?
Yes. Subtitle Edit has a command-line interface: SubtitleEdit /convert *.sup SRT /ocrengine:Tesseract. The browser tool processes one file at a time and is best for individual conversions.
Why does Subtitle Edit only run on Windows?
Subtitle Edit was built on .NET Framework, which was historically Windows-only. While .NET Core is cross-platform, Subtitle Edit has not been ported. This browser tool works cross-platform as a practical alternative.
