Text & Subtitle Replacer

About Bulk Text & Subtitle Replacer

The Bulk Text & Subtitle Replacer on wesharekh is a browser-based tool for replacing multiple words, names, phrases, or other text patterns in a single operation. It is useful for translators, subtitle editors, writers, video creators, and anyone who needs to make repeated text changes across a large document.

The tool supports both regular text and SRT subtitle files, making it possible to update subtitle names, terminology, translations, or repeated phrases without manually editing every occurrence.

Key Features

Multiple Replacement Rules

Add multiple Find and Replace with rules and apply them in a single batch. This is useful when several words or phrases need to be changed in the same document.

SRT Subtitle Support

Load an .srt subtitle file and replace text while keeping the existing subtitle structure. Subtitle sequence numbers and timing information can remain unchanged while the matching text is updated.

Text File Support

You can also work with ordinary text by pasting it directly into the editor or loading a supported .txt file.

Browser-Based Processing

Text processing is designed to happen directly in your browser. Your document does not need to be uploaded to a separate online text processing service.

How to Replace Multiple Words at Once

1. Step 1: Paste your text into the editor or upload a supported .txt or .srt file.
2. Step 2: Add the original word or phrase to the Find field.
3. Step 3: Enter the new word or phrase in the Replace with field.
4. Step 4: Add additional replacement rules for other words or phrases.
5. Step 5: Click Run Batch Replacement to apply the rules.
6. Step 6: Review the resulting text, then copy it to your clipboard or download the processed file.

Using the Tool with SRT Subtitles

SRT files contain subtitle sequence numbers, timestamps, and dialogue text. When you need to change a name or phrase throughout a subtitle file, manually editing every occurrence can be time-consuming.

The Bulk Text & Subtitle Replacer allows you to define replacement rules and apply them to the subtitle text while preserving the existing SRT structure.

For example, if a character's name was translated incorrectly throughout a subtitle file, you can add the old name as the Find value and the corrected name as the Replace with value.

What Can You Use It For?

• Updating names throughout subtitle files.
• Correcting repeated translation mistakes.
• Changing terminology across a document.
• Replacing multiple phrases in a text file.
• Updating company or product names.
• Editing repeated words in SRT subtitles.
• Making batch changes to long documents.
• Preparing subtitle files before video editing or publishing.

Why Use Batch Replacement?

Manually searching for and changing dozens or hundreds of occurrences can be slow and can lead to missed matches. Batch replacement lets you define the changes once and apply them across the document in a single operation.

This is especially useful when working with long subtitles, translated documents, scripts, or other text containing repeated names and terms.

SRT Subtitle Structure

A typical SRT subtitle contains three important parts: a sequence number, a start and end timestamp, and the subtitle text. For example:

1
00:00:01,000 --> 00:00:04,000
Hello, welcome to the video.

When replacing subtitle text, the timing information should not need to change simply because a word or phrase has been replaced. The tool is designed to modify matching text while retaining the existing subtitle structure.

Privacy and Local Processing

The tool is designed to process text and subtitle files directly in your browser. This means your documents can remain on your device instead of being sent to a remote text-processing service.

Because processing happens in browser memory, the practical amount of text you can process depends on your device, browser, and available memory.
