Which PDF editors are worth considering?
There are plenty of PDF editors available, but the most popular options include UPDF, Adobe Acrobat and PDF Expert.
Adobe Acrobat remains the most well-known PDF editor on the market — and also the most expensive at US$239.88/yr. For businesses and professionals who need advanced PDF capabilities, it’s still a solid choice.
PDF Expert is designed specifically for the Apple ecosystem, making it an excellent choice for Mac, iOS, and iPadOS users. It delivers robust functionality, but it’s only available on Apple devices.
