I was creating an eBook for my client using Canva, and I found that Canva limits the number of pages to 30 pages per design.
If you’re making a little report 30 pages may be enough. Canva gives clear instructions on creating longer books
I used merge PDF tool and I’m happy with the result. Very quick and easy to use. I merged 3 separate PDFs, saved the final PDF file and emailed the file with no problems.
By the way, if you’ve never used Canva try it now, it’s one of the most awesome tools ever 🙂
