Which one is for you
Pick SwifDoo PDF if
- Fits if you want a cheap PDF editor on Windows
- Works for people who prefer a lifetime license for one PC at $96.75
Look elsewhere if
- Pricey if you pay monthly, at $16.99 for the Windows plan
- Watch out: Mac, iOS and Android have separate price pages, and a cross-platform plan starts at $26.99 a month
- Watch out: the page shows a crossed-out price with no end date, and the source holds a second, lower set
- Watch out: it states a 30-day money-back guarantee but the refund FAQ just says to email support
- Tight if you want 2 devices, since monthly and quarterly plans cover 1
Pick UPDF if
- Fits if you edit on a laptop and a phone and want one license for both
- Makes sense if you'd rather pay $79.99 once than rent your PDF editor
Look elsewhere if
- Skip it if you need a browser version, as there isn't one
- Not for you if you want the AI on the one-time license, as it's sold separately
- Tight if you stay on the free version, with 2 conversions a day and a watermark
- Watch out: the Mac App Store edition lacks OCR; you need the updf.com download for it
- Watch out: prices are from the US App Store, as updf.com showed a bot check, so the website may charge differently
How we grade them
| 2.8GPASwifDoo PDFGood | 3.0GPAUPDFVery good | |
|---|---|---|
| Value for money | BThe 2-year plan is $2.88 a month and the yearly plan $4.50, inside the cheapest quarter ($4.17) or just over it; the monthly plan is $16.99. | A$49.99 a year on the US App Store, among the lowest-priced paid editors here, and one license covers every platform. The $79.99 perpetual license, spread over three years, costs less still, though the AI isn't in it and updf.com may charge differently. |
| Free plan and trial | C7-day trial of Pro, and the free download is limited afterwards; the listing does not say a card is needed. | CThere's a free version, but it's 2 conversions a day, AI on 5 files and a watermark on anything you save. Fine for a look around, not for real work. |
| Features | BText and image editing, conversion, OCR, fillable forms, annotation, signing and an AI tool. The listing shows no gap in the core work. | BEdits text and images, converts to Office and PDF/A, OCRs in 38 languages, builds forms, redacts, compares and batch-processes, with Bates numbers. It covers the whole job. The Mac App Store edition leaves out OCR; the updf.com download has it. |
| Ease of use | BNo rating on record; a program you install and use, with nothing to set up. | BNo store rating on record. It's an app you install and start editing in, with nothing to set up first. |
| Platforms and integrations | BWindows, Mac, iOS and Android. No web editor and no integrations listed. | BWindows, Mac, iPhone and Android, synced through UPDF Cloud, plus Dropbox. No browser version and a short integration list, so it stops at B. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
