Bring your Anki decks. Keep your schedule.

STEP BY STEP

Import an Anki deck into Klappa in five steps.

The whole process is one export in Anki and one import in Klappa. Nothing in your Anki collection changes.

1. Export the deck from Anki In Anki desktop, open File, then Export. Choose Anki Deck Package (.apkg) and pick the deck. Its subdecks come with it.
2. Keep scheduling and media switched on Leave Include scheduling information and Include media ticked. With scheduling off, Anki strips each card's progress from the file, and the deck arrives as new cards.
3. Open the Anki Portal in Klappa Sign in, open the Anki Portal and press Import .apkg in the header.
4. Drop the file or browse for it Klappa reads the package, stores its images and audio, and shows a progress bar while it works. The page stays responsive during a large import.
5. Check the counts, then study When it finishes, Klappa lists how many models (note types), decks, notes, cards and media files it imported. Press Done and the deck is in your portal, ready to study or browse.

WHAT CARRIES OVER

What comes across from Anki, and what does not.

Klappa reads old and new Anki package formats. It renders cards through its own implementation of Anki's template syntax, so fields, cloze, conditionals and custom CSS carry over. Scripts inside card templates do not run.

Each card's current schedule is imported. The individual review log, one row per past answer, is not: Klappa starts its own log from your first review in Klappa.

LARGE COLLECTIONS

Big decks on the website, and on a Mac.

On the website, a single .apkg can be up to 1.9 GB, and the collection inside it must open within the same 1.9 GB once decompressed. Files of 250 MB or more are streamed rather than loaded whole, so a media-heavy deck does not have to fit in memory at once. Media from these large files is kept on the device you imported on; notes and scheduling sync everywhere.

A deck past that limit gets one plain message instead of a failed upload. On a Mac browser it points you to Klappa for Mac, which does not use the website's upload cap and reads the collection with a native reader.

For scale, a 39.1 MB pathology deck with 3,605 cards and 556 media files reached its first studyable card in 47.3 seconds in our own timed run on the website.

THREE WAYS IN

Anki Portal, Klappa Library, or a new deck.

Anki Portal: study it the Anki way

Import .apkg keeps the deck as an Anki deck, with its note types, schedule, custom study, filtered decks and a card browser. Choose this when you want your progress to continue.

Add to Klappa Library: a separate copy

From a portal deck's menu, Add to Klappa Library renders the deck's cards into ordinary Klappa cards in a new private deck. The Anki deck is never changed, and the copy starts its own schedule.

Create a deck from a .apkg

When you create a new deck, you can start from a .apkg. Klappa turns Basic, Cloze and multiple-choice note types into cards you can edit right away, with their images and audio.

NO LOCK-IN

Export back to Anki whenever you want.

1. Open the deck's menu In the Anki Portal, open the menu on the deck row and choose Export .apkg.
2. Decide on review history On the website, tick Include review history to add the reviews you did in Klappa. Leave it off and the file still carries the cards and their current schedule.
3. Import the file in Anki The package contains a fresh collection plus your media, and imports into Anki desktop like any other deck.
