Subtitle Edit

Overview

Subtitle Edit is a free, open-source subtitle editor for people who need to create, refine, or convert subtitles across desktop platforms. It suits independent editors with varied workflows especially well; its extensive toolset is a strength, though it does not provide stated team or administrator controls.

Subtitle Edit 5 is the cross-platform version, built on Avalonia. Its documentation, FAQ, and contributing guidance support a project maintained at SubtitleEdit. Support for formats including SRT, WebVTT, and ASSA gives editors room to work with common subtitle types, while styling and speaker identification help shape the finished captions.

Key features

Recognition, translation, and proofreading

Speech-to-text support includes Whisper, Qwen3 ASR, Crisp ASR, and related engines. That breadth is useful for editors who want recognition options within one subtitle workflow, rather than a tool focused only on manual timing. Automatic translation and advanced local translation engines extend the workflow to other languages. Proofreading with llama.cpp, Ollama, or an OpenAI-compatible endpoint adds another review step, although the choice of engine means users may need to bring their own setup.

OCR and video processing

Multiple OCR engines, including Tesseract, PaddleOCR, and cloud engines, can extract text embedded in video images. Burn-in, re-encoding, cutting, and remuxing tools also keep common video tasks close to subtitle work. This makes Subtitle Edit a practical fit for editors handling both captions and source footage; someone seeking only a lightweight text editor may find this scope unnecessary.

Styling, export, and automation

Caption styling, speaker identification, brand caption presets, and export to other formats address both presentation and delivery. The seconv command-line utility supports headless conversion, scripts, and bulk conversion, which is particularly useful when repetitive jobs need automation. Plugin documentation adds scope for extensions, but users who want managed team workflows should look elsewhere: no sharing or administrator controls are stated.

Pricing

Subtitle Edit is free and open-source. The Free plan has no stated free-tier limits, making it a strong option for individual editors who need the full described workflow without a subscription. No trial or refund policy is stated.

Platforms

Subtitle Edit supports Windows, macOS, and Linux. The cross-platform documentation covers Subtitle Edit 5, an Avalonia-based version, so it is relevant to desktop users across all three operating systems.

Who it's for

Choose Subtitle Edit if you need more than text-and-timing edits: its recognition, OCR, translation, video-processing, and batch-conversion tools serve independent subtitle creators with varied or repeatable tasks. It is less suitable for teams that need shared workspaces or administrator controls, and the range of features may be excessive for someone seeking only a basic editor.

Pros and cons

• Pros: Free and open-source, with no stated free-tier caps, so the described toolkit does not come with a stated usage ceiling.
• Pros: Recognition, OCR, translation, proofreading, and video-processing options cover multiple stages of subtitle production.
• Pros: seconv supports scripts and bulk conversion, a meaningful advantage for repetitive workflows.
• Cons: No team, sharing, or administrator controls are stated, limiting its fit for coordinated group work.

Verdict

Subtitle Edit is the right choice for independent editors who want a no-cost, cross-platform toolkit spanning subtitle creation, recognition, translation, OCR, and video work. Its command-line conversion capability is an added reason to choose it for repeatable jobs. Look elsewhere if team controls are essential or if you only need a narrowly focused editor.
