Last updated: October 2026
Bottom line up front: PDF Expert by Readdle is one of the best PDF editors for Mac, iPhone and iPad in 2026 — fast, clean and native-feeling, with editing, annotation, signing, OCR, conversion and an AI assistant called PDF Copilot that summarises, answers questions about and translates your documents. It is Apple-only: Readdle states that PDF Expert is not available for Windows. If you live on a Mac and want Acrobat-level everyday editing without Acrobat’s weight, it is a strong choice; start with the free trial.
Readdle says PDF Expert has 30 million users, a 4.7-star rating across more than 200,000 reviews, and recognition from Apple as an Editors’ Choice and App of the Year runner-up.
What Is PDF Expert?
PDF Expert is a PDF editor developed by Readdle, a Ukrainian software company known for building premium productivity apps for Apple platforms. It runs on macOS, iPadOS and iOS and covers the full range of PDF work: reading, annotating, editing text and images, filling forms, signing, merging and managing pages, converting to Word, Excel and PowerPoint, translating and recognising text in scans (OCR).
Readdle’s design philosophy shows throughout the app: common features are one or two clicks away, the interface is uncluttered, and navigation through long PDFs is quick. It is not a stripped-down viewer; it is a full editor that happens to be well designed.
PDF Copilot: The AI Features
PDF Expert’s AI lives in PDF Copilot. According to Readdle, it can:
- Summarise a PDF based on its most important information.
- Answer questions about the document’s content — “what is the termination clause?” rather than a keyword search.
- List the main points and takeaways.
- Explain specific terms, phrases or passages.
- Translate sections into other languages.
- Generate quizzes from the content — useful for students.
- Summarise your annotations and comments in one place.
PDF Copilot works on macOS 13 and later and iOS 16 and later, and Readdle also offers a web version. Separately, an AI-powered Enhance feature fixes distortions, removes shadows and improves contrast in scanned documents. As with any AI summary, check anything important — obligations in a contract, figures in a report — against the original text.
Core Editing and Annotation
Beyond AI, PDF Expert’s core functionality is polished. Text editing lets you change text directly in a PDF, image editing covers adding and replacing images, and page management handles merging, reordering, extracting and splitting with drag and drop.
Annotation tools are where PDF Expert excels: highlights, underlines, strikethroughs, notes, stamps and freehand drawing from a persistent toolbar, with Apple Pencil support on iPad for marking up papers and drawings. Form filling and signing let you complete forms and add saved signatures.
PDF Expert vs Adobe Acrobat vs Apple Preview, Criterion by Criterion
Most Mac owners are really choosing between three things: the free Preview app that ships with macOS, PDF Expert, and an Acrobat subscription. Here is how they line up on what each vendor publishes, checked on 16 October 2026.
- Editing the text already in a PDF. Preview: no — Apple’s own Preview guide says you can’t edit the text of a PDF in Preview and points you to its markup tools instead. PDF Expert: yes, “Edit PDF text, images, and links” is on its premium feature list. Acrobat: yes, on Standard, Pro and Studio (“Edit text and images in PDFs and automatically adjust formatting”).
- Turning scans into searchable, editable text (OCR). Preview: not among its listed markup tools. PDF Expert: yes, “Recognize text (OCR)” is a premium feature. Acrobat: Adobe lists “Turn scans into editable PDFs” for Pro and Studio, not for Standard.
- Converting to Word, Excel and PowerPoint. Preview: no. PDF Expert: yes. Acrobat: yes, on all three plans.
- Signing. Preview: you can place a saved signature with its Sign tool. PDF Expert: “Sign documents” is included. Acrobat: all three plans include “Sign documents, request signatures, and track responses” — the request-and-track part is what PDF Expert’s feature list does not claim.
- AI assistant. Preview: none. PDF Expert: PDF Copilot is part of the premium plans. Acrobat: AI Assistant is included only in Acrobat Studio; Adobe’s comparison marks it as not a feature of Standard or Pro.
- Platforms. Preview: Mac only, free with macOS. PDF Expert: Mac, iPhone and iPad, plus a web version of PDF Copilot; not Windows. Acrobat: Adobe says it works on desktop, mobile and in the browser.
- Getting out. PDF Expert: both paid plans carry a 30-day money-back guarantee. Acrobat: monthly plans cancel any time with no fee; annual plans billed monthly charge a fee of up to half the remaining commitment if you cancel after 14 days; annual prepaid plans give no refund after 14 days.
The pattern is clear. Preview covers reading, markup and a saved signature for nothing. PDF Expert adds real text editing, OCR, conversion and an AI assistant on Apple devices. Acrobat is the one to pay for if you need Windows, signature requests with tracking, or a single licence across mixed hardware.
PDF Expert Pricing and What a Year Actually Costs
Readdle prices PDF Expert in the visitor’s local currency, so the figures you see depend on where you are. On 16 October 2026 its pricing page showed us two plans, priced in kroner:
- Yearly: 899.00 kr billed annually, covering the iPhone, iPad and Mac versions.
- Lifetime: 1,790.00 kr as a one-time payment, for the Mac version only. Readdle adds that “additional new features may come at an extra cost”.
Worked example. On those published prices, three years of the yearly plan costs 3 × 899 = 2,697 kr against 1,790 kr once for Lifetime, and Lifetime pays for itself shortly before the end of year two (1,790 ÷ 899 ≈ 1.99 years). That sum only holds if you work on a Mac alone. If you also edit on an iPad or iPhone, Lifetime does not cover them, and only the yearly plan does. Whatever your currency, the same ratio is the quick test: divide the Lifetime price by the yearly price, and if you expect to use the app on a Mac for longer than that many years, Lifetime is cheaper.
In the US Mac App Store, the PDF Expert listing shows in-app purchases of $139.99, $79.99 and $39.99, but does not say which plan or billing period each one is, so do not read them as annual prices. The same listing says the app requires macOS 12.0 or later, while Readdle states PDF Copilot needs macOS 13 or later — on an older Mac you can run the editor but not the AI assistant.
For comparison, Adobe’s US pricing page lists Acrobat Pro at US$19.99 a month on an annual plan billed monthly, US$239.88 a year prepaid, or US$29.99 month to month; Acrobat Studio, the only individual plan with AI Assistant, is US$24.99, US$299.88 and US$34.99 on the same three terms. Do not compare these with the kroner figures above: they are different currencies and regions. Check the current PDF Expert price for your country before deciding. Readdle’s PDF Copilot page offers premium features free for 7 days, so you can test on your own files first.
Best Use Cases
Students benefit from PDF Copilot’s summaries, explanations and quizzes, plus annotation on iPad with Apple Pencil. See our guide to AI tools for students.
Lawyers and other professionals benefit from asking questions of long contracts, summarising annotations for review, and fast navigation in large documents — with the usual rule that an AI summary is a starting point, not legal analysis.
Freelancers and small businesses get editing, signing and conversion in one app without an enterprise subscription. See also our guide to AI tools for freelancers.

Frequently Asked Questions
Is PDF Expert free?
You can download it and try the premium features in a free trial; Readdle’s PDF Copilot page offers premium features free for 7 days. After that, editing and AI features need a paid plan. In October 2026 the pricing page listed a yearly plan (covering iPhone, iPad and Mac) and a one-time Lifetime licence for Mac only.
Is PDF Expert available for Windows?
No. Readdle’s help centre states that PDF Expert is not available for Windows; it runs on Mac, iPhone and iPad.
Is the PDF Expert Lifetime licence worth it?
Only if you work on a Mac alone and expect to keep using it for roughly two years or more. On the prices Readdle showed us (899 kr a year against 1,790 kr once), Lifetime breaks even just before year two. It does not cover iPhone or iPad, and Readdle says new features may cost extra.
Can I edit PDF text in Preview on a Mac?
No. Apple’s Preview guide says you can’t edit the text of a PDF in Preview; you can add text boxes, shapes, notes and a saved signature on top. To change the existing words you need an editor such as PDF Expert or Acrobat.
Is PDF Expert better than Adobe Acrobat?
For many Apple users, yes: it is lighter, faster to work in and feels native to macOS and iOS. Acrobat is better if you need Windows or Android, advanced form creation, or enterprise e-signature and review workflows.
Does PDF Expert have AI?
Yes. PDF Copilot summarises documents, answers questions about them, lists main points, explains passages, translates text, generates quizzes and summarises annotations. It runs on macOS 13+ and iOS 16+, with a web version as well.
Can PDF Expert edit scanned documents?
Yes, on the Mac. Its OCR recognises text in scans so you can search and edit it; Readdle’s help centre says OCR is in PDF Expert for Mac 3.0 or later and is not yet in the iPhone and iPad app. The AI Enhance feature fixes distortions, removes shadows and improves contrast in scanned pages.
