Which one is for you
Pick Adobe Acrobat if
- Fits if your clients send Acrobat files and expect them back marked up
- Works for anyone who only reads and signs PDFs, using the free Reader
Look elsewhere if
- Pricey if you just fix the odd typo, since editing starts at $14.99 a month on a yearly plan
- Tight if you're on Standard and need OCR, redaction, compare or bulk signing, as all need Pro at $19.99
- Watch out: month to month costs $10 more on each plan, and the AI Assistant is a $4.99-a-month add-on below Studio
- Skip it if you want to buy once and be done: Acrobat Pro 2024 covers three years of desktop use, with no price on record
- Not for you if you want to try Standard first, as only Pro and Studio get the 7-day trial
Pick callas pdfToolbox if
- Fits if you run print production and need preflight with automated fixes
- Works for shops that want checks run from hot folders or a command line
Look elsewhere if
- Not for you if you want a price, because none is published
- Too light for everyday PDF editing, as it is a preflight and correction tool
- Watch out: it cannot create ICC or DeviceLink profiles, only apply them
- Skip it if you want a clear trial, since the length and limits are not stated
How we grade them
| 2.6GPAAdobe AcrobatGood | 1.8GPAcallas pdfToolboxWeak | |
|---|---|---|
| Value for money | DStandard, the cheapest plan that edits, is $14.99 a month on a yearly plan, and OCR, redaction and compare need Pro at $19.99. That's the top of what PDF editors charge. Acrobat Pro 2024 is sold once for three years of desktop use, but no price for it is on record. | CNo price is published and buyers are sent to local partners and a license server, so it sits at C. |
| Free plan and trial | CAcrobat Reader is free for good and views, comments on and signs PDFs, but it won't edit or convert, which is the job here. The 7-day trial covers Pro or Studio, and Standard has no trial at all. | DA Try for free registration is offered, but its length and limits are not stated. |
| Features | BEdits text with reflowing layout, converts Office files, OCRs scans, compares versions, redacts, runs batch actions and sends documents to sign in bulk. It covers the whole job, though a lot of that sits on Pro rather than Standard. | CCustomizable preflight profiles, hot-folder server, a command-line tool and an SDK. It does the preflight job fully but it is a narrower job than editing: it cannot create ICC or DeviceLink profiles. |
| Ease of use | B4.64 from 661,119 App Store ratings for the Acrobat Reader app, just shy of the top grade. Most people have opened a PDF in it already, so there's not much to learn. | CNo store rating is on record, and profiles, hot folders and a command-line tool mean configuring it before use. |
| Platforms and integrations | AWindows, Mac, web, iPhone, Android and a browser extension, plus Microsoft 365, Teams, Outlook, OneDrive, Google Drive, Dropbox and Box. Six platforms in all. | CMac and Windows computers, plus a server, a command line and an SDK, with Acrobat Pro and Enfocus Switch links. No phone or web app. |
| Best for | editing, OCR, redaction and signing in one app | checking and fixing PDFs for print production |

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.
