Functionally there is no difference: .sqlite, .db, .sqlite3, and .db3 are just different naming conventions for the same SQLite database format. SQLite itself does not require any particular extension because it identifies a file by a 16-byte header at the start, not by its name, so a database called data.db and one called data.sqlite open identically. The extensions are conventions chosen by different apps — many Android and iOS apps use .db, some desktop tools default to .sqlite or .sqlite3, and .db3 occasionally appears. As long as the file is a valid SQLite database, the engine reads it the same way regardless of the label. This viewer accepts all four extensions, so you can drop in any of them and immediately browse the tables inside.

You can open a .db file directly in your browser instead of installing a desktop client like DB Browser for SQLite or running command-line tools. Drag or select the file in this viewer, and it loads into a SQLite engine compiled to WebAssembly that runs on your own machine. Once loaded, the tool lists every table, so you can click a table to page through its rows, switch to a query tab to run your own SQL, or open the schema tab to read each table's structure. There is no setup, no account, and no upload step — the database is read locally, which keeps confidential contents private. This is the fastest way to peek inside a stray .db file from a bug report, an app's storage folder, or a teammate, without committing to any installation.

Yes. Beyond browsing tables, this viewer includes a query tab where you can type and execute arbitrary SQL against the loaded file. SELECT statements return a results grid you can read or export, while statements that change nothing visible simply report that they ran successfully. Press Ctrl+Enter, or Cmd+Enter on a Mac, to run without reaching for the mouse. Because it uses a full SQLite engine, joins, aggregates, WHERE clauses, ORDER BY, and other standard syntax all work as they would in a desktop database. If a statement has an error, the engine's message is shown verbatim, which makes the box handy for testing a query before pasting it into your real codebase. Everything runs locally, so even repeated queries stay fast and private. Load a file and open the SQL Query tab to try one.

In SQLite, NULL is a distinct value that means "no data" or "unknown," and it is not the same as an empty string or a zero. A column can legitimately hold a NULL when a row never had a value set for that field, which is different from a cell that contains an empty piece of text. Confusing the two causes real bugs, because comparisons like column = '' will not match a NULL, and you need IS NULL instead. To make this distinction obvious, the viewer prints NULL explicitly in italic rather than leaving the cell blank, so you can tell at a glance whether a value is truly absent or just an empty string. Browse any table and you will see NULLs clearly labeled, which helps when you are auditing data quality or debugging missing values.

Because this viewer reads the entire database into your browser's memory rather than streaming it from a server, the practical size limit is your device's available RAM, not a fixed server quota. Small and mid-sized databases — the kind most apps create, often a few megabytes to a few hundred — open almost instantly. Very large dumps in the multi-gigabyte range can strain memory and may load slowly or fail, especially on a phone or a tab that already has many pages open. That trade-off is the cost of keeping your file fully private, since nothing is uploaded. If you hit a limit on a huge file, closing other tabs frees memory, and you can always narrow a browse to one table or a targeted query. For typical app databases, just upload the file and start exploring.
