What is DBConverter?

The Free Online Database Converter
Built for Developers

DBConverter is a free online database converter that handles every SQL dialect difference automatically. MySQL uses backticks and AUTO_INCREMENT. PostgreSQL uses double quotes and SERIAL. SQLite ignores column types entirely. Moving data between them means rewriting syntax by hand — or using DBConverter.

Upload your file, pick the target format, and download a result you can import directly. No command line, no configuration, no account. The whole process takes under a minute.

How It Works

Three Steps to a Converted Database

The whole process takes under a minute, even for large files.

📤

Upload your file

Drag and drop or click to browse. We accept SQL dumps, SQLite files, CSV spreadsheets and JSON data up to 50 MB. The source format is detected automatically.

🎯

Choose your target

Pick the format you want. You only need to choose the destination — source detection is automatic. Preview your tables before committing.

📥

Download the result

Your converted file is ready in seconds. Download it and import it straight into your database. The original is deleted after two hours.

          MySQL → PostgreSQL
        
-- Before (MySQL)
CREATE TABLE `orders` (
  `id` INT AUTO_INCREMENT PRIMARY KEY,
  `paid` TINYINT(1) DEFAULT 0,
  `created` DATETIME
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
-- After (PostgreSQL)
CREATE TABLE "orders" (
  "id" SERIAL PRIMARY KEY,
  "paid" BOOLEAN DEFAULT FALSE,
  "created" TIMESTAMP
);

Smart Conversion

The Database Converter That Handles Every Syntax Difference

Most database converters just rename the file extension. DBConverter actually rewrites the SQL — identifiers, data types, engine declarations, auto-increment syntax — so you get a file that imports cleanly on the first try, every time.

AUTO_INCREMENT

→ SERIAL / AUTOINCREMENT

TINYINT(1)

→ BOOLEAN / INTEGER

`backticks`

→ "double quotes"

DATETIME

→ TIMESTAMP / TEXT

ENGINE=InnoDB

→ removed cleanly

INSERT IGNORE

→ ON CONFLICT DO NOTHING

See your tables, columns and sample rows before you convert. No surprises in the output.

Fast processing

Most files convert in under five seconds. Large files up to 50 MB handled without timeouts.

Smart type mapping

Data types mapped intelligently between engines. INT, SERIAL, BOOLEAN, TIMESTAMP all handled correctly.

Auto format detection

Drop any file and we figure out the format from the extension and file contents automatically.

Private by design

Files processed and deleted within two hours. We never read or store your data.

SQL formatter built in

Clean up messy SQL queries with proper indentation and keyword casing in one click.

CSV and JSON support

Import spreadsheet data into a database or export tables to CSV for Excel or Google Sheets.

Column renaming

Rename tables and columns as part of the migration. Generate a custom script for your target schema.

Privacy & Security

Your Database Files Are Never Stored

When you upload a file, it lives on our server only long enough to perform the conversion. After two hours, both the original and the converted file are deleted automatically. We never read the contents of your database, never index it, and never share it.

There is no account system. That means no email address, no password, no profile — nothing tied to your identity. You use the tool and leave. That is it.

FAQ

Common Questions

Everything you need to know before you start converting.

Is DBConverter really free?

Yes, completely. No account, no credit card, no usage limits. All five tools are free for everyone, always.

How big can my file be?

Up to 50 MB. If your database is larger, export it in chunks or split the tables across multiple files.

Is my data safe?

Your files are processed on our server and deleted automatically within two hours. We never read or store the contents of your database.

Which formats are supported?

MySQL and MariaDB SQL dumps, SQLite database files (.sqlite, .db), PostgreSQL dumps, CSV files and JSON data files. You can convert between any combination.

Can I convert a SQL query without uploading a file?

Yes. The Query Converter tool lets you paste any SQL query and convert it between MySQL, PostgreSQL and SQLite syntax without uploading anything.

What is the difference between SQL to SQLite and SQL to PostgreSQL?

SQL to SQLite strips server-specific syntax and maps types to SQLite equivalents like TEXT and INTEGER. SQL to PostgreSQL replaces AUTO_INCREMENT with SERIAL, converts TINYINT(1) to BOOLEAN and removes MySQL engine declarations.

Can I convert CSV to SQL online for free?

Yes. Upload your CSV file, select CSV as the source and MySQL, PostgreSQL or SQLite as the target. The tool reads your header row as column names and generates a complete CREATE TABLE and INSERT script.

What if the conversion has errors?

The preview shows you the table structure before you download. If something looks wrong, check that your source file is a valid export from the original database.
