Wave Subs review
A free, open-source desktop tool for local subtitle creation, translation, and batch workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Wave Subs is a free, open-source desktop application for generating and translating video subtitles on macOS and Windows. It uses local Whisper models for speech recognition, aligns subtitle timing automatically, and supports translation into 29 target languages. The workflow suits creators, localization teams, and viewers managing subtitle files across individual videos, folders, or seasons. Videos can remain on the computer, and the application does not require an account.
Its strongest advantage is the combination of local processing and practical subtitle controls. Wave Subs exports SRT and ASS files, includes a subtitle editor with video preview, and supports embedded or external subtitle tracks. Batch processing helps with larger collections, while glossary-based translation is designed to keep terminology consistent. Optional on-screen text recognition and translation extends the workflow beyond spoken dialogue. For teams that need different model providers, the application supports OpenAI-compatible APIs alongside OpenAI, Anthropic Claude, Google Gemini, DeepSeek, Qwen, Zhipu GLM, Moonshot, Volcano Ark, SiliconFlow, OpenRouter, and Azure OpenAI.
The trade-off is a desktop-focused workflow rather than a broader browser or publishing platform. Local recognition and translation emphasize control over video handling, but API-based translation depends on configuring a supported provider. Wave Subs is a strong choice for users who want open-source subtitle generation, multilingual translation, batch processing, and editable subtitle files. It is less suited to teams seeking a hosted collaboration environment or a single service that handles video publishing after subtitle creation.
