"Your collection size is large" suggestions

NameLessGO · April 30, 2025, 9:06pm

Recently there has been a rise of reports: “your collection is large” in 25.02.04

Could we display these values in MBs to help users understand how much they are currently storing

Collections on AnkiWeb are limited to a compressed size of 100MB, and an uncompressed size of 250MB. This includes the text on your cards and the scheduling information, but does not include sounds/images, as they are stored separately.
Are there limits on file sizes on AnkiWeb? - Anki FAQs

Does the prompt above talks about compressed or uncompressed values? Also, please add a note indicating the collection size that Ankiweb supports (e.g., 100MB or 250MB)

While rare, could Anki provide subscription for values >250mb?

“Note Size” addon can show some details about collection size. However, there is a some difference between exact “collection size” in Anki Desktop and Anki Web.

Recently, I asked this forum how to Get AnkiWeb collection size programmatically. But now, Anki Web has no API to provide this information for Anki Desktop.
It’d be great, if AnkiWeb developers implement disclosing details about collection size.

FYI: I opened a PR hoping to solve this issue here:

github.com/ankitects/anki

CHANGE collection size too large error to add MB values and info about compressed vs. uncompressed.

fixes: https://forums.ankiweb.net/t/your-collection-size-is-large-suggestions/60…084 I have added a conversion from bytes to MB and passed this to the error function instead of just the bytes. I also added the info that this is the uncompressed value, not the compressed value. **Important:** I don't know how to trigger this error without having an account and a large enough collection, so couldn't actually test it. I'm not sure whether it's okay to create a test ankiweb account for these kind of things and I'd not be sure how to create a collection large enough to be affected by this restriction anyways. I'd love to know how I could test this! `./check` does pass though.

And the max size is defined here for those interested, so maybe an API isn’t neccessary:

github.com/ankitects/anki

rslib/src/sync/request/mod.rs

main


      
          pub static MAXIMUM_SYNC_PAYLOAD_BYTES: LazyLock<usize> = LazyLock::new(|| {
              env::var("MAX_SYNC_PAYLOAD_MEGS")
                  .map(|v| v.parse().expect("invalid upload limit"))
                  .unwrap_or(100)
                  * 1024
                  * 1024
          });
          /// Client ignores this when a non-AnkiWeb endpoint is configured. Controls the
          /// maximum size of a payload after decompression, which effectively limits the
          /// how large a collection file can be uploaded.
          pub static MAXIMUM_SYNC_PAYLOAD_BYTES_UNCOMPRESSED: LazyLock<u64> =
              LazyLock::new(|| (*MAXIMUM_SYNC_PAYLOAD_BYTES * 3) as u64);
