SQL Input
This free online PostgreSQL to SQLite SQL converter translates your CREATE TABLE DDL scripts between dialects instantly — with no server upload, no account, and no rate limits. Paste your PostgreSQL schema on the left and the converted SQLite DDL appears on the right in real time. All conversion logic runs entirely in your browser, keeping your database schema 100% private and secure.
Code & Data Generator
How PostgreSQL column types map to their SQLite equivalents, with migration notes for each type.
| PostgreSQL Type | SQLite Equivalent | Notes |
|---|---|---|
| SERIAL / BIGSERIAL | INTEGER | INTEGER PRIMARY KEY auto-increments in SQLite (rowid alias) |
| INTEGER / INT / BIGINT | INTEGER | SQLite stores all integers as up to 8-byte signed int |
| BOOLEAN / BOOL | INTEGER | SQLite uses 0/1 for booleans |
| REAL / FLOAT / DOUBLE PRECISION | REAL | 8-byte IEEE float |
| NUMERIC(p,s) / DECIMAL(p,s) | NUMERIC | SQLite NUMERIC affinity; may store as INTEGER or REAL |
| VARCHAR(n) / TEXT / CHAR(n) | TEXT | SQLite has no length limit on TEXT |
| BYTEA | BLOB | Binary Large Object |
| TIMESTAMP / TIMESTAMPTZ | TEXT | SQLite stores as ISO 8601 string: '2024-01-15 09:30:00' |
| DATE | TEXT | Store as 'YYYY-MM-DD' |
| TIME | TEXT | Store as 'HH:MM:SS' |
| UUID | TEXT | SQLite has no UUID type; store as 36-char string |
| JSONB / JSON | TEXT | SQLite 3.38+ has json_extract() for TEXT columns |
| SERIAL PRIMARY KEY | INTEGER PRIMARY KEY | SQLite rowid alias — auto-increments |
Everything you need to know about converting PostgreSQL to SQLite.
Paste your PostgreSQL CREATE TABLE statements into the SQL editor on the left. The SQLite output appears instantly on the right panel in real-time as you type.
Yes — completely. The entire conversion runs inside your browser using JavaScript. Your SQL is never sent to any server, logged, or stored anywhere. This makes it safe to use with production or confidential database schemas.
PostgreSQL, MySQL, SQLite, SQL Server, Oracle, and MariaDB DDL syntax are all supported. The parser auto-detects the dialect from your CREATE TABLE syntax automatically.
Yes! Paste multiple CREATE TABLE statements separated by semicolons and all tables will be converted simultaneously, including cross-table foreign key relationships.
Yes. NULL, NOT NULL, DEFAULT values, PRIMARY KEY, UNIQUE, and FOREIGN KEY constraints are all parsed and reflected in the SQLite output. Nullable columns are correctly typed as optional properties or nullable types.
Yes, SchemaForge is completely free with no usage limits, no account required, and no rate limits. The tool runs entirely in your browser and will always be free.
