SQLite Viewer: Open and Browse .db Files

No. A compiled SQLite build runs inside your browser using WebAssembly, so the file is read directly from your device and never sent to a server. You can even open a database offline once the page and engine have loaded.

Any SQLite database file, regardless of extension. The drop zone accepts the common ones by default: .sqlite, .sqlite3, .db and .db3. If a file uses a different extension but is a real SQLite database, it will still open.

This is a read-only viewer. SELECT and PRAGMA statements work well for exploring, but any changes are not written back to your original file. To edit a database, use a desktop tool such as DB Browser for SQLite.

When you click a table the tool runs a preview query with LIMIT 100 to stay fast on large tables. The Data heading shows the full row count, so if a table has more you can write your own query with a higher LIMIT or a WHERE clause to see the rest.

Empty cells display the word NULL in a muted style so they are easy to tell apart from an empty string. Binary BLOB columns are not dumped as raw bytes; instead they show a placeholder like [BLOB 2048 bytes] that reports the size.

The query box will attempt whatever you type, but the tool is built for read-only browsing, and results are shown as grids. Stick to SELECT and PRAGMA statements. Statements that would modify data have no lasting effect because nothing is saved back to the file.

The entire database is loaded into memory, so small and medium files open almost instantly. Very large files, in the hundreds of megabytes or more, may load slowly or hit your browser's memory ceiling, since everything must fit in RAM.

Each results grid has a Copy TSV button that puts the rows on your clipboard as tab-separated values with a header row. You can paste that straight into a spreadsheet or a text file.
