Calaméo vs iSpring Flip

Calaméo is an online platform for turning PDFs into interactive digital publications, including magazines, brochures, catalogs, and other documents.

They are readable on computers, tablets, and smartphones through an HTML5 viewer. BASIC is free, and eligible BASIC users can request one free 14-day PLATINUM trial before the account returns to BASIC. Document limits vary by plan: BASIC allows up to 100 MB and 500 pages, PREMIUM allows 100 MB with unlimited pages, and PLATINUM allows 500 MB with unlimited pages. Private-publication caps are 5 on BASIC, 500 on PREMIUM, and 2,500 on PLATINUM. Downloads and printing require PREMIUM or PLATINUM, and are unavailable in the mobile viewer.
