Import from Anki

Flashnerd can import Anki deck packages (.apkg) and collection packages (.colpkg). It converts the content into Flashnerd decks, fields, and SRS data where supported.

Keep the original Anki export. Conversion is not guaranteed to preserve every custom Anki template or rendering behavior.

Import a package

  1. Export the package from Anki and make it available in your phone's file picker. Include media in the source export if you need images or audio.
  2. In Flashnerd, open Home or SRS, open the create menu, and choose Import.
  3. Under Import From, select Anki, then use Upload File to choose the .apkg or .colpkg file.
  4. Tap Next once the file is ready.
  5. In Review decks (2/2), examine the Home and SRS previews. Turn on Include study progress if you want the available schedules and review history; it starts off.
  6. Read every warning, then tap Import.

After completion, open the imported decks, preview both sides of several cards, and check images and audio. If you imported SRS data, also inspect the set and its due counts before beginning a long review session.

Anki imports create independent copies. Override existing is available only for Flashnerd files, so importing the same Anki package again does not update the earlier imported copy.

Understand conversion warnings

WarningMeaning and next step
Cards imported as notes onlyThe original template is unsupported. Front and back are blank; assign fields to Front, Back, or Both in the deck template before studying or exporting.
Missing images or audioReferenced media was unavailable. Those fields are left blank. Check the original package and re-export with media if necessary.
Image occlusion adapted to rectanglesSome original mask shapes changed. Inspect the resulting masks before studying.
Content adjusted to import limitsRead the affected counts. Cards or tags may have been omitted, or long labels shortened.
Study progress could not be loadedSchedules and history cannot be included from this file. Decide whether to import content only or obtain another export.

Turning off Include study progress imports the content without the file's schedules and review history. Imported history can affect statistics differently from reviews completed directly in Flashnerd; it should not be treated as a perfect recreation of every historical Anki metric.

Important limits

  • Up to 20,000 cards per source deck are retained, in source-card ID order; excess cards are reported and omitted.
  • Up to 20 template fields after conversion. If the converted template needs more fields, simplify the source before retrying.
  • Up to 5 tags per card are retained.
  • A deck or set may sit below up to 6 nested folders.
  • Each imported image or audio file must be no larger than 10 MiB.

Large archives also have processing limits, including a 128 MiB decoded collection database and 50,000 ZIP entries. Device storage must accommodate preparation as well as the final content. A small compressed package can still exceed a decoded-data limit.

If preparation fails, do not repeatedly import blindly. Read the error, free storage or simplify the source as appropriate, and retry. See Troubleshooting and Backups.
