How to Edit SRT Subtitle Files Online
SRT Snap makes subtitle editing simple and fast. Follow this guide to edit your SRT files, sync subtitles with video, and export in multiple formats.
Upload Your SRT File
Click the Upload tab and drag your .srt file onto the upload area, or click to browse and select it from your computer. SRT Snap supports files up to 50MB. Your file stays on your device โ nothing is uploaded to any server.
Edit Subtitle Text and Timing
Use the built-in text editor to modify subtitle text directly. Each subtitle entry shows its sequence number, timing (start and end), and caption text. You can add new subtitles, delete entries, or adjust timestamps. For a visual editing experience, upgrade to Pro to unlock the timeline editor with drag-and-drop controls.
Preview Your Subtitles
Click the Preview tab to see how your subtitles will look on screen. The preview simulates a video overlay with adjustable playback speed. Click individual subtitle blocks to jump to specific timestamps and verify readability, timing, and formatting.
Export Your Subtitle File
Once your subtitles are ready, click Export .srt to download the edited file. Pro users can also export to ASS (Advanced SubStation Alpha) for advanced styling, VTT (WebVTT) for HTML5 video, and TXT for plain text transcripts.
The professional multi-track timeline editor is exclusive to Pro users.

Frequently Asked Questions About SRT Subtitle Editing
What is an SRT file and how do I edit it?
An SRT (SubRip Subtitle) file is a plain-text format that stores video subtitles with timing information. Each entry contains a sequence number, start and end timestamps in HH:MM:SS,mmm --> HH:MM:SS,mmm format, and the caption text. You can edit SRT files with any text editor, but SRT Snap makes it easy with a dedicated editor, preview mode, and a Pro timeline editor with video sync and drag-and-drop controls.
Can I use SRT Snap for free?
Yes! The free tier includes the basic SRT text editor, preview mode, and SRT export. For professional subtitle editing with video integration, the Pro plan at $50 lifetime unlocks the professional timeline editor with vocal detection for automatic speech syncing, drag-and-drop subtitle blocks, batch operations, and multi-format export to ASS, VTT, and TXT.
How does the vocal detection and auto-sync feature work?
SRT Snap Pro uses audio frequency analysis to detect speech segments in your video's audio track. The editor analyzes zero-crossing rates and energy levels to identify vocal sections, then creates subtitle blocks automatically aligned with the spoken content. You can then fine-tune the timing using the drag-and-drop timeline interface. This feature is ideal for content creators who need to quickly sync subtitles to dialogue.
Is my data safe? Do you store my files?
Your privacy is our priority. SRT Snap runs entirely in your web browser using JavaScript โ there are no servers, no uploads, and no data storage. Your SRT files and video content never leave your computer. This 100% client-side architecture means you can edit sensitive subtitle content with complete peace of mind.
What video and subtitle formats are supported?
The free tier supports importing and exporting SRT (SubRip) format. Pro users can export to ASS (Advanced SubStation Alpha), VTT (WebVTT), and plain TXT formats. The Pro timeline editor supports MP4, WebM, AVI, and MOV video files, and can also attempt to extract embedded subtitle tracks from MP4 and MKV containers.
How do I upgrade to Pro and activate my license?
Purchase a Pro license via PayPal for a one-time payment of $50. You'll receive a license key (format: SRTN-XXXX-XXXX-XXXX) by email. Enter this key in the License section of the app to activate lifetime access. You can also register an account to manage your license across multiple devices. If you lose your key, email SpoiledAvocado.discord@gmail.com with your PayPal transaction ID for recovery.
Can I edit subtitles while watching the video?
Yes! The Pro timeline editor features a synchronized video player with real-time subtitle preview. As you play the video, the current subtitle is highlighted in the timeline and displayed as an overlay on the video. You can drag subtitle blocks to adjust timing, resize their duration, click to seek to any position, and see changes reflected immediately โ similar to professional editing software.
