Open one and blank page. It know how many pages are in the pdf but no text. ### 5/5 — Excellent *2024-03-25* Free, Light, easy to use, with ads but respects your personal datas. ### 1/5 — App removes digital signatures from PDFs when reading these! *2024-01-10* App removes digital signatures from PDFs. Totally defeated the purpose of using PDFs for contracts. Uninstalled. ### 1/5 — Crashes when Deleting Pages of a PDF *2023-12-20, version 1.7* It’s a pretty useless app if you use it to remove pages from a PDF file because it just crashes after a few pages are deleted. It returns you to the file unmodified. ### 1/5 — Crashing App *2023-12-01* This app keeps crashing as I airdrop documents from my laptop over to this device. Not impressed. ### 1/5 — Горе программисты *2023-08-24* Бестолковое приложение ### 1/5 — Don’t Bother *2023-07-19* It will just close while you’re working, it closes when you’re trying to email a file and there’s no way to move through the document except page by page. ### 1/5 — waste of time *2023-07-14* you need to buy premium to literally do anything ### 1/5 — You cannot type *2023-04-03* I thought this PDF app was the type you could edit by typing actual text from your IPhone keyboard but NO! You can ONLY draw which is crazy to offer a PDF in this form. ### 1/5 — People actually pay for this? *2023-03-12* This has to be the worst pdf app I have ever seen. Was this a school project for third graders? Certainly seems like it was. Wait, nah they would have made something better then that ## Frequently asked questions about Smart PDF Editor ### What does Smart PDF Editor do?
