Is converting SQL dump to MySQL free?

Yes. Files up to 10MB convert free with no account. There is a limit of five conversions per day per IP address.

Will my SQL dump data keep its types in MySQL?

Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real MySQL types rather than everything becoming text. The mapping table above shows exactly what you get.

Do you store my file?

No. The file is written to a temporary directory, converted, and the directory is deleted as soon as your download has been sent.

Convert SQL dump to MySQL

Upload a .sql file and get back a MySQL SQL script you can load straight into your database. Types are preserved rather than flattened to text. Free, no registration, up to 10MB.

How your data is typed in MySQL

Generated from the converter's own MySQL type mapping — this is what it actually emits, not an example.

Your data	MySQL type
Whole number	BIGINT
Decimal (money)	DECIMAL(10,2)
Floating point	DOUBLE
True / false	TINYINT(1)
Date	DATE
Date and time	DATETIME
Short text	VARCHAR(255)
Long text	LONGTEXT
Binary data	LONGBLOB

Working from a .sql file

A .sql file is only text containing statements, so what you get out depends entirely on which statements are in it. Schema and data both have to be present for the result to be a database rather than an empty shell.

→Four things are used: CREATE TABLE, ALTER TABLE ... PRIMARY KEY, INSERT and COPY. Views, triggers, stored procedures, indexes and GRANT statements are read past rather than converted.
→A file with INSERTs but no CREATE TABLE still produces its rows, with a warning that the columns are unnamed - the file never said what they were called.
→A file with neither comes back with "No CREATE TABLE or INSERT statements were found", which usually means the schema lives in a second file.
→psql meta-commands - the lines beginning with a backslash, like \connect - are client directives rather than SQL, and are skipped before parsing.

Loading the dump into MySQL

The download is a plain SQL script, so nothing in it depends on how you connect: the same file goes in through the command-line client, through a GUI import dialog or through phpMyAdmin. What is worth reading first is the handful of statements it runs before it creates anything.

→Before the first CREATE TABLE the script issues SET NAMES utf8mb4, so the session decodes the file as UTF-8 whatever the client's own default character set is. The file itself carries no marker saying so.
→The line after it turns FOREIGN_KEY_CHECKS off. That is there for the schema you are loading into, not for the script: it lets rows arrive in whatever order the tables came out of the source without a constraint that already exists rejecting them.
→A true/false column is declared TINYINT(1) and its values are written as 1 and 0. MySQL's own BOOLEAN keyword expands to exactly that, so a client that does not special-case the width shows you a number rather than a boolean.

Reading SQL dump

→Parsed with a real SQL parser, not regular expressions, so a value containing a closing parenthesis or a semicolon cannot split a row in half.
→CREATE TABLE types, primary keys, NOT NULL and AUTO_INCREMENT are all read from the dump.
→The source dialect is detected from the dump itself — MySQL, PostgreSQL and SQL Server dumps all parse.

Writing MySQL

→Tables are created as InnoDB with utf8mb4, so emoji and CJK text survive the load.
→Backslashes are escaped, because MySQL treats them as escape characters by default.
→Text columns of unknown length become TEXT rather than a guessed VARCHAR that could truncate your data.
→Inserts are batched, and identifiers are capped at MySQL’s 64-character limit.

What you get

A ZIP containing dump.sql, plus a README with the exact command to load it. If anything about your data needed a judgement call, a _warnings.txt explains it.

Load this dump into MySQL or MariaDB:

  mysql -u USER -p DATABASE < dump.sql

Create the database first if it does not exist:

  mysql -u USER -p -e "CREATE DATABASE DATABASE CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"
