Adobe InDesign is the industry-standard page layout tool for print and digital publishing: master pages, paragraph styles, data merge, EPUB export and interactive PDFs.
Single-app ~$22.99/month (annual), $31.49/month cancel-anytime, ~$263.88/year paid upfront. Students/teachers $19.99/month. Teams/business $84.99/month. Also available bundled in Creative Cloud All Apps.
Editorial designers, publishers and marketing teams producing multi-page documents (brochures, magazines, reports, ebooks) where layout consistency across dozens of pages matters.
Best value comes from bundling into Creative Cloud All Apps if Illustrator/Photoshop are also needed. Paying for InDesign alone is comparatively expensive versus the bundle for teams using multiple Adobe apps.
Professional page layout and design software.
