Viewing, inspecting and verifying. You get the table list, with row counts and browsable contents for each table. File details, exact byte size and the detected signature are always shown.
How to open a .db file
DB files come from Apps, phones, browsers, and the usual advice — buy the software that made it — is rarely what you need just to look inside one. This page covers what the format is and how to open it in a browser tab.
What is a .db file?
Generic Database is a database format developed by various, first appearing in 1990. It is normally produced by Apps, phones, browsers.
Usually SQLite in practice — phone apps, browsers and desktop tools all default to it. Check for the 'SQLite format 3' string at offset 0.

Open a .db file in your browser
OpenAnyFile routes .db to its SQLite database browser, which opens the table list, with row counts and browsable contents for each table.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .db file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the SQLite database browser.
- Your DB opens on its own viewer page: the table list, with row counts and browsable contents for each table.
- Use fullscreen for a closer look, or download the file back out unchanged. Free, and free in the sense that there is no paid tier waiting behind step three.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Is it safe to open a {E} file on a website?
It depends entirely on whether the website uploads it, and almost all of them do. That is a real problem when the databases file in question is a contract, a client deliverable or something under NDA. OpenAnyFile removes the question: the decoding happens inside your browser tab, so there is no transfer, no queue, no temporary storage and no retention window to read about in a privacy policy.
Frequently asked questions about DB files
Can I open a .db file without installing special software?
Yes. OpenAnyFile's SQLite database browser runs in your browser, so you can read a DB file with nothing installed. You get the table list, with row counts and browsable contents for each table. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a DB file?
Look at the first bytes rather than the extension. A genuine DB begins with 53 51 4C 69 74 65 (often). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .db by mistake is easy to spot.
Is it safe to open a DB file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .db file, exactly?
Generic Database — an application/octet-stream format created by various since 1990. Usually SQLite in practice — phone apps, browsers and desktop tools all default to it. Check for the 'SQLite format 3' string at offset 0.
Does the same viewer handle formats related to DB?
Yes — the same engine also opens .sqlite, .pdb, .sqlite3, so you can compare related files without switching tools.

These open with the same engine, so if you have one of these sitting next to your .db file, it will open too:
