If you want to contribute scans to a manga
archive responsibly, here's how I usually handle it.
First off, always check the archive's submission rules and copyright policy. Plenty of archives only accept public-domain material or works where permission has been granted by the rights holder. If the archive allows community uploads, they’ll typically have a contributor guide explaining file types, resolution, and metadata requirements. I make contact with an admin or mod before doing anything major — a quick email or forum DM avoids wasted effort and possible takedowns.
Next, prepare your files neatly: scan at a clean resolution (often 300 DPI is recommended), save master images in lossless format like PNG or TIFF, and produce web-friendly JPEGs for the archive if instructed. Include a plain-text metadata file with title, author, original publisher, translator credit, scan date, and licensing/permission notes. If you don’t have permission, consider offering to upload only text translations or summaries instead, or help with public-domain works. Doing things
by the book keeps the archive healthy and shows respect to creators — I always sleep better knowing I did it properly.
