I can rely on the softwares’ performance and accuracy when it comes to converting PDFs to application files. We recently had a 250 page art book, with over 200 images that was created in CANVA. Working for a publisher, we had to make edits for the author! This software was a "file-saver!!!"

Oh, amazing! It’s the next big thing. It’s very easy. I switched, recently, from Adobe products entirely to Affinity products. The biggest benefit I see is that it gives the people, the designers, the publishing houses, the freedom to get out of the the padlock situation with Adobe.
