Which one is for you

Pick PDFgear if

  • Fits if you want an editor that changes existing text without paying or signing up
  • Works for Windows and Mac users dropping a paid editor for everyday edits

Look elsewhere if

  • Skip it if you need Linux, as there's no version for it
  • Not for you if files must never leave your computer, as some conversions upload to its Amazon cloud servers
  • Tight if you're building your work around it, as some advanced features may become paid
  • Watch out: it's a young product, first out in 2022, and paid for by investment rather than sales
  • Too light for sending documents to sign inside the app, as that's on eSignGear, a separate site

Pick Skim if

  • Fits if you read and mark up papers on a Mac, especially with LaTeX or BibDesk
  • Works for anyone who wants a free annotator and not an editor

Look elsewhere if

  • Skip it if you use Windows, Linux or a phone, as it runs on Mac only
  • Too light for editing text or filling in forms, since neither is listed
  • Watch out: support is a wiki, mailing lists and bug trackers, not a help desk
  • Tight if your Mac is old, because the current version needs macOS 10.13

Value for money
ANothing to pay, and it edits existing text, converts, OCRs and has AI. The maker says investment pays for it, not ads or selling data. Some advanced features may become paid later.
AFree to download and use, with no paid tier, so it sits well under the cheapest quarter of PDF tools.
Free plan and trial
AEvery feature on every platform, with no signup, no ads and no caps on record. The maker says some advanced options may become paid.
AThe whole app is free, with nothing held back.
Features
BEdits text, images and form fields like a word processor, batch-converts to Office, OCRs in 30-plus languages, annotates and has an AI copilot. It covers the whole job. Sending for signature is on eSignGear, its separate site.
CNotes, highlights, snapshots, a reading bar and AppleScript. It does that job fully, but it is a smaller one: the listing shows no text editing or form filling.
Ease of use
BNo store rating on record. No account to make and nothing to set up: install it and start editing.
BNo store rating is on record, but it is a program you install and open, with nothing to set up.
Platforms and integrations
BWindows, Mac, iPhone, iPad, Android, the web and a browser extension. That's everywhere bar Linux, but integrations stop at ChatGPT and its own eSignGear, so no top grade.
DmacOS only, version 1.7.19 needing macOS 10.13 or higher. There is no Windows, phone or web version.

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.
