SQLITE SQLite Database
SQLite Database is a database format commonly identified by .sqlite, .sqlite3, .db. Use the listed signatures, MIME types, and structure notes to validate files beyond the extension.
Extensions .sqlite, .sqlite3, .db
MIME application/vnd.sqlite3

Caveats
- Do not trust the extension alone. Check the MIME type, the first bytes such as 53 51 4C 69 74 65 20 66 6F 72 6D 61 74 20 33 00, and format-specific structure when possible.
- Container formats and damaged files can share the same opening bytes, so deeper validation may be required for production upload, preview, or conversion flows.
Detection example
SIGNATURE = bytes.fromhex("53514c69746520666f726d6174203300")
OFFSET = 0
def is_sqlite(path: str) -> bool:
with open(path, "rb") as f:
f.seek(OFFSET)
head = f.read(len(SIGNATURE))
return head == SIGNATUREconst SIGNATURE = [0x53, 0x51, 0x4c, 0x69, 0x74, 0x65, 0x20, 0x66, 0x6f, 0x72, 0x6d, 0x61, 0x74, 0x20, 0x33, 0x00];
const OFFSET = 0;
// bytes: a Uint8Array / Buffer holding the start of the file
export function isSqlite(bytes) {
return SIGNATURE.every((byte, i) => bytes[OFFSET + i] === byte);
}package fileid
import "bytes"
var issqliteSignature = []byte{0x53, 0x51, 0x4c, 0x69, 0x74, 0x65, 0x20, 0x66, 0x6f, 0x72, 0x6d, 0x61, 0x74, 0x20, 0x33, 0x00}
const issqliteOffset = 0
func IsSqlite(b []byte) bool {
end := issqliteOffset + len(issqliteSignature)
if len(b) < end {
return false
}
return bytes.Equal(b[issqliteOffset:end], issqliteSignature)
}const SIGNATURE: &[u8] = &[0x53, 0x51, 0x4c, 0x69, 0x74, 0x65, 0x20, 0x66, 0x6f, 0x72, 0x6d, 0x61, 0x74, 0x20, 0x33, 0x00];
const OFFSET: usize = 0;
fn is_sqlite(bytes: &[u8]) -> bool {
bytes.get(OFFSET..OFFSET + SIGNATURE.len()) == Some(SIGNATURE)
}<?php
$signature = "\x53\x51\x4c\x69\x74\x65\x20\x66\x6f\x72\x6d\x61\x74\x20\x33\x00";

}Practical usage
Use cases
SQLite Database is used for data exchange, imports, exports, parser testing, and validation workflows. Encoding, delimiters, versions, and container structure often change implementation behavior.
Common detection mistakes
- The .sqlite / .sqlite3 / .db extension alone does not prove the file contents. Upload and conversion flows should combine extension, MIME type, leading bytes, and format-specific structure checks.
- SQLite Database can start with signatures such as 53 51 4C 69 74 65 20 66 6F 72 6D 61 74 20 33 00, but related containers and damaged files may require additional validation.
Security notes
Untrusted input is not safe just because the format was detected. Account for parser exceptions, large files, unexpected encodings, and external references.

What is the magic number (file signature) of SQLite Database?
SQLite Database files begin with the byte signature 53 51 4C 69 74 65 20 66 6F 72 6D 61 74 20 33 00 ("SQLite format 3."). Detect the format by reading these leading bytes rather than trusting the file extension alone.
What is the MIME type of SQLite Database?
The MIME type for SQLite Database is application/vnd.sqlite3.
What file extension does SQLite Database use?
SQLite Database files use the .sqlite, .sqlite3, .db extension. The extension is a convention only and does not guarantee the file contents, so combine it with signature and structure checks.
