Buyer questions
Questions buyers actually ask
How many files can I convert at once?
A batch can contain up to 200 files, 1 GB of files in total, and each file can be up to 50 MB. Processing happens in your browser, so available device memory can still affect very large files.
Are my subtitle files uploaded to a server?
No. All conversion happens entirely in your browser using JavaScript. Your files never leave your device, which makes the batch converter safe to use even for confidential or unreleased content.
Is the batch subtitle converter free to use?
Yes, the batch converter is free with no sign-up and no watermarks. Batches are limited to 200 files, 1 GB total, and 50 MB per file. It runs in any modern browser on Windows, macOS, Linux, and mobile devices.

The expert review
AllSubConverter scores 77/100 for a broad, privacy-first subtitle workspace with strong task coverage and clear technical guidance. Its main weakness is that the large tool catalog needs a more unified help and onboarding path, while mobile lab performance remains slower than its real-user field results.
