APKG Viewer — open .apkg files online, no Anki needed

What is an .apkg file?

An .apkg file is the standard shared-deck format exported by Anki, the free flashcard app used by millions of learners. It is a zip archive containing a SQLite database of your notes and cards, plus any images, audio and video used by the cards.

Why open .apkg in your browser?

• No Anki software to install
• Works on any device with a modern browser
• No account, no registration
• Files are parsed locally — never uploaded
• Progress saved locally (IndexedDB)

What can the APKG viewer do?

• Browse every card in the deck
• Render images, audio and cloze deletions
• Review with a full SM-2 spaced-repetition scheduler (Again / Hard / Good / Easy)
• Track progress locally, per deck

Is .apkg the same as .colpkg?

No. A .colpkg is a backup of an entire Anki collection; an .apkg is a single shared deck. Both open in Anki Browser — see the COLPKG viewer.

FAQ

Is my .apkg file uploaded to a server?

No. The file is opened and parsed entirely on your device using WebAssembly. Nothing is ever sent over the network.

Do I need to install Anki to use this viewer?

No. Everything runs in your web browser — no installation required.

Does it work on my phone or tablet?

Yes — any modern browser on Windows, macOS, Linux, iOS or Android.

Can I actually study the deck, not just view it?

Yes. Anki Browser includes the classic SM-2 scheduler with Again / Hard / Good / Easy buttons, exactly like Anki.

Does it support images, audio and cloze deletions?

Yes. Media files stored in the deck render inline, and cloze notes are supported.
