Why Do You Need an SQL Splitter?
Working with large SQL database dumps is a common challenge for developers. Whether you're migrating a website, setting up a local development environment, or just backing up data, you've likely encountered the dreaded import timeout error. Web-based tools like phpMyAdmin or Adminer have strict limits on file size and script execution time. Trying to upload a file that's hundreds of megabytes (or even gigabytes) will almost always fail.
This tool solves that problem by breaking your massive SQL file into smaller, independent chunks that can be uploaded one by one without hitting server limits.
Why Choose Our Tool Over Others?
-
100% Secure and Private
Unlike other online tools, our splitter runs entirely in your browser. Your SQL file is never uploaded to a server. All processing happens locally on your computer, guaranteeing the privacy of your sensitive data.
-
Intelligent Splitting Logic
A simple split can break your SQL. Our tool is smart: it never splits in the middle of a multi-line `INSERT` statement and automatically copies the necessary header/footer statements to each chunk, preventing common session and character set errors.
-
Feature-Packed for Developers
We support `.sql` and compressed `.gz` files, offer splitting by line count or file size, and provide a "Download All as ZIP" feature to streamline your workflow. It's built for efficiency.
