Usage

anyflip-downloader <url to book>

Set title manually

If you do not want to use the book title from anyflip, you can change it using the -title flag.

anyflip-downloader -title <your book title> <url to book>

Specify temporary download folder path

The default temporary download folder path will be the title of the book. However, in certain situations, you might want to change the temporary download folder. For this, the -temp-download-folder flag exists. This folder will be deleted after a successful download.

anyflip-downloader -temp-download-folder <temp folder name> <url to book>

Define converting chunk size

By default, anyflip downloader will convert 10 images at a time. You can tell anyflip to convert more or less images at a time.

A lower number will result in less memory usage, but more writes to the drive, and therefore might increase time to convert. A higher number will result in more memory usage, but less writes and might increase converting speed. If the number is higher than the total amount of pages, the amount of pages currently being converted is automatically taken instead.

anyflip-downloader -chunksize <chunkzise> <url to book>

Advanced file download options

Parallel retrieval

By default, downloads are performed in a single thread. To improve performance, multiple pages can be downloaded simultaneously. Use the -threads flag to control the number of parallel jobs.

anyflip-downloader -threads <number of parallel jobs> <url to book>

Download retries

Occasionally, a request may fail due to temporary issues such as timeouts. Use the -retries flag to specify how many times a failed page should be retried before giving up:

anyflip-downloader -retires <number of attempts> <url to book>

Retry delay

To avoid overwhelming the server or triggering rate limits, you can introduce a delay between retry attempts. The -waitretry flag accepts any valid Go duration format (e.g., 500ms, 2s, 1m).

anyflip-downloader -waitretry <duration> <url to book>
