Text File Splitter

Text File Splitter

Quickly and safely split large text documents or log files right in your browser. Choose between "Rows", "Files", or "Size" modes to slice your files into the perfect portions for your needs.

How to Use
STEP1

Import File

Simply drag and drop the text file (.txt, .log, .csv, etc.) you want to split onto the screen, or click the "Select File" button.

STEP2

Specify Split Method

Choose a split mode: "Rows", "Files", or "Size" according to your needs, and enter the required value.

STEP3

Execute and Save

Click the "Split Text File" button. Once the split is complete, download each file individually or save them all together as a ZIP file.

Features

Fully Browser-Based for Security

All uploaded text files are processed entirely on your device. No data is sent to external servers, allowing you to safely split log files that contain sensitive information.

Strict Size Splitting in MB/KB

Split files exactly by your specified size (MB or KB) to match upload limits. Go beyond simple row counts with flexible text data splitting directly in your browser.

3 Flexible Split Modes

We offer flexible modes for any scenario: split by rows for system limits, by files for easy distribution, or by file size for upload constraints.

Ideal For

Investigating Large Log Files and Text Data

Break down error logs or access logs that are too large to open in a standard text editor into readable chunks, keeping your troubleshooting process smooth.

Data Splitting for System Migrations

Split large text data that cannot be imported all at once based on the destination system's limits (such as max rows or file size) to ensure a safe and error-free migration.

Sharing Large Documents

Break down text documents that are too large to attach to emails or send via chat tools into smaller, shareable sizes for your team members.

FAQ
Will splitting cause corrupted characters or broken lines?
No. Even when using the size-based mode, we do not simply cut off at a hard byte limit. Instead, the split safely occurs at the "first line break after the specified size", preventing any lines from being cut in half.
What is the maximum file size that can be processed?
While it depends on your browser and computer's memory, our chunk-reading technique allows for stable splitting of files even in the gigabyte range. Note that bulk ZIP downloads have browser limitations, so please use individual downloads for extremely large files.
What character encodings are supported?
We support text files in virtually any character encoding. Because the text is split at the binary level based on the line feed (\n) character, the output files will safely retain their original encoding.
