Best PDF Expert Alternatives in 2026 (Free and Paid)

PDF Expert by Readdle has earned a loyal following, particularly among iPhone and iPad users. It is one of the most polished PDF applications available on iOS and macOS, with a clean interface, reliable annotation tools, a capable editing experience, and deep integration with Apple’s ecosystem. For Apple users who need a premium mobile PDF editor, it has been the default recommendation for years.

The cost is where things get complicated. PDF Expert has moved away from one-time purchase pricing toward a subscription model. The current pricing is around $6.99 per month or $49.99 per year for the premium features, which includes PDF editing, format conversion, and the more advanced annotation tools. For users who process PDFs occasionally on their iPhone or iPad, that is a significant ongoing cost for a task that more capable free tools now handle without a fee.

PDF Expert is also primarily an Apple product. Windows and Android users are not the target audience, and the cross-platform experience for users who move between devices is limited compared to tools that offer consistent functionality across all platforms. If you use an iPhone, an Android phone, and a Windows laptop in the same week, PDF Expert covers only part of that workflow.

The alternatives below offer strong PDF processing across all devices and platforms, often at no cost, and cover the everyday tasks that most PDF Expert users actually need.

Quick comparison

PDFHaul

PDFHaul is a privacy-first PDF platform with native iOS and Android apps and a full web app. It is completely free with no daily task limits, no watermarks, and no account required to start. For PDF Expert users who are primarily motivated by the mobile experience, PDFHaul is the strongest free alternative with apps built natively for both iOS and Android rather than being a web experience wrapped in an app shell.

The tool set covers the operations that make up the majority of mobile PDF work: merging, splitting, compressing, rotating, reordering pages, removing duplicates, removing blank pages, converting between PDF and image formats, signing, annotating, highlighting, redacting, and editing metadata. The mobile apps are designed specifically for touch interfaces and the experience on an iPhone or iPad reflects that, with a responsive and fast workflow that does not feel like a desktop tool adapted for a smaller screen.

After uploading a document, a full viewer and editor opens where annotation, signing, highlighting, redacting, and other operations are available in a single session. For PDF Expert users who have paid for the app primarily to annotate documents, sign files, and occasionally merge or compress something, PDFHaul covers those workflows at no cost across both iOS and Android.

The cross-platform consistency is a meaningful advantage over PDF Expert for users who work across multiple devices. PDFHaul’s web app, iOS app, and Android app offer a consistent experience regardless of which device you are using, which is particularly relevant for users who switch between Apple and non-Apple devices.

Privacy is handled transparently. Every upload is encrypted using TLS 1.3, files are stored encrypted at rest, and everything is permanently deleted within 2 hours. That deletion timer is visible in the product. For users uploading sensitive documents from their phone, that level of transparency is reassuring.

Best for: PDF Expert users who want a free, cross-platform alternative with strong native mobile apps for both iOS and Android and a full in-browser editing workflow.

PDFgear

PDFgear is the closest free alternative to PDF Expert’s desktop experience on Mac. It is completely free across Mac, Windows, iOS, and Android, with full text and image editing, annotation, form filling, e-signatures, compression, and an AI document assistant. For Mac users who have been using PDF Expert on desktop and want a comparable free alternative, PDFgear is the strongest option currently available.

The iOS app is well-reviewed and covers annotation, signing, form filling, and basic editing without a subscription. For users who want to move away from PDF Expert’s subscription pricing but stay within a downloaded application model, PDFgear replicates most of the everyday functionality at no cost.

The AI features are an addition that PDF Expert does not currently match, including document summarisation and natural language querying of PDF content. For users who work with long or complex documents and need to extract information quickly, that is a meaningful advantage.

The main limitation compared to PDF Expert is polish. PDF Expert has spent years refining its iOS and macOS experience and the attention to detail in the interface shows. PDFgear is well-designed but the depth of Apple ecosystem integration, including features like Apple Pencil optimisation, Handoff, and Sidecar support, is more developed in PDF Expert.

Best for: Mac and iOS users who want a free desktop and mobile PDF editor that approaches PDF Expert’s feature set without a subscription.

PDF24

PDF24 is primarily a web and Windows desktop tool and is not the natural replacement for PDF Expert’s Apple-first mobile experience. However, for PDF Expert users who primarily need a capable free tool for desktop PDF processing and are comfortable moving to a web-based workflow, PDF24 covers more operations than most alternatives at no cost.

The tool breadth of over 40 PDF operations means that specialised tasks occasionally needed alongside the everyday ones are available without a separate tool. The Windows PDF24 Creator app provides local processing for users who prefer not to upload files to a server.

Best for: users switching from PDF Expert who primarily work on desktop and want the widest range of free PDF tools.

Smallpdf

Smallpdf is a web-based PDF platform with iOS and Android apps. The free tier is limited to two tasks per day, and the paid plan at around $9 per month unlocks unlimited use and collaboration features. For PDF Expert users who need a capable tool that works well across devices and includes e-signature workflows and document sharing, Smallpdf is a reasonable step between a mobile-focused editor and a full collaboration platform.

The AI features on paid plans add document summarisation and querying capabilities that go beyond what PDF Expert currently includes. For professionals who work with long documents and need to extract information quickly, that is worth considering.

Best for: users moving away from PDF Expert who need cross-device access and are willing to pay a modest fee for collaboration and AI features.

iLovePDF

iLovePDF is a reliable web tool with iOS and Android apps that covers standard PDF operations without a subscription. For PDF Expert users whose primary use case is merging, compressing, converting, and signing documents rather than deep annotation or editing, iLovePDF covers those workflows competently at low or no cost.

The free tier has restrictions and the premium plan at around $4 per month is the most affordable paid option in this list. The mobile apps are functional but the product is web-first in its design, which means the mobile experience does not match the native feel of PDF Expert or PDFHaul.

Best for: PDF Expert users who need a simple cross-platform tool for standard PDF tasks and are not primarily motivated by the mobile experience.

Why people look for PDF Expert alternatives

The subscription pricing shift is the most common reason. PDF Expert was previously available as a one-time purchase and the move to subscription billing has prompted many users to reconsider whether the cost is justified for their actual usage patterns.

The Apple-only limitation is the second reason. PDF Expert is excellent within the Apple ecosystem but offers nothing for Android users and limited functionality on Windows. As more professionals work across mixed device environments, a tool that covers all platforms becomes more valuable than one that excels on a single one.

The third reason is that the gap between PDF Expert and free alternatives has narrowed considerably. Tools like PDFgear and PDFHaul now offer annotation, signing, and editing capabilities that approach PDF Expert’s for everyday tasks at no cost, which changes the value calculation for users who are not using the more advanced features that justify the subscription.

Frequently asked questions

Is there a free PDF Expert alternative for iPhone?

Yes. PDFHaul has a native iOS app that is completely free with no daily task limits, covering annotation, signing, merging, compressing, converting, and other common PDF operations. PDFgear also has a well-reviewed free iOS app with full editing capabilities. Both are genuinely free without the paywall that PDF Expert’s premium features sit behind.

Which PDF Expert alternative works on both iPhone and Android?

PDFHaul works on both iOS and Android with native apps on each platform, as well as a full web app for desktop use. PDFgear also covers both platforms. Both provide a consistent experience across Apple and non-Apple devices, which is a significant improvement over PDF Expert’s Apple-focused approach.

Can free alternatives match PDF Expert for annotation?

For everyday annotation including highlighting, underlining, adding notes, inserting text, and drawing, PDFHaul and PDFgear both cover the core use cases at no cost. Where PDF Expert maintains an edge is in the depth of Apple Pencil integration and the refinement of the annotation experience on iPad specifically. For users who do heavy stylus-based annotation on iPad as their primary workflow, PDF Expert remains the most polished option. For everyone else, the free alternatives are functionally comparable.

Does PDF Expert work on Android or Windows?

PDF Expert is available for iOS and macOS only. There is no Android app and no Windows desktop application. For users who work across mixed device environments, this is a meaningful limitation that tools like PDFHaul, PDFgear, and Smallpdf address by offering consistent functionality across all major platforms.
