Why authors choose Authordocks
Built by an indie author who got tired of formatting headaches.

Private by design
Your manuscript and artwork are processed on your own device, not uploaded to a server.
Questions
Does it really work on a phone?
Yes. Save the file to your phone and open it in your browser. Export works from the phone too, so you can produce your interior and cover PDFs without a computer.
Is it a subscription?
No. The tools are a one-time purchase on Gumroad, and you keep the file.
Will my files be uploaded anywhere?
No. The tools run in your browser, so your manuscript and images stay on your device.
Does it work with KDP, IngramSpark and other printers?
Yes. Set your trim size, bleed and spine to match any printer. The cover tool has presets for Amazon KDP, IngramSpark and home print, for paperback and hardcover. Always check your final files against your printer's current specs before you publish.
Will I lose my work?
Your project autosaves on your device, and you can save a backup file any time. On a phone, save your project regularly, because browsers can clear stored data.
Which tool should I get?
If you're making a picture book, get Layout Lab Max: you write, lay out and export the whole book, and the cover tool is built in. If you only need a cover (for any type of book, including novels and non-fiction) or just image upscaling, the single tools are cheaper.
