PDFBook vs PDF-XChange Editor

Perpetual licence.Until they revoke the installer.

In May 2025 PDF-XChange removed download access to older installers for users whose maintenance had expired, leaving valid lifetime-license holders unable to reinstall the software they had paid for. PDFBook is a privacy-first PDF reader and library for Windows, macOS, and Linux. $89 once for Lifetime, with a written commitment that re-download stays available for life, no maintenance gate, even if we go out of business.

Why people leave PDF-XChange Editor

Common frustrations with PDF-XChange Editor from public reviews, and how PDFBook solves each.

May 2025: "perpetual license" customers locked out

Trustpilot reviewers report that after formatting a PC three years after purchase, they discovered PDF-XChange no longer offered the installer for the version they legally owned, despite holding a valid serial key. The company's own forum confirms the policy: installer access is removed roughly 90 days after maintenance expires. PDFBook commits to keeping your version's installer available for re-download: your purchase doesn't expire when our "maintenance window" does.

The EULA hid the catch

PDF-XChange Co. Ltd's defence is that the EULA only ever promised a perpetual license key, never perpetual installer access. From the user's perspective that's a bait-and-switch: most consumers reasonably understand "perpetual license" to include the ability to reinstall. PDFBook publishes a plain-English Lifetime commitment alongside the legal text.

No mass-email warning

Reviewers reported no email, no banner, no notification before installer access was revoked: they discovered it only when reinstalling after a system rebuild. PDFBook commits in writing that any policy that would affect existing Lifetime customers will be announced 90 days in advance via email and a banner on the manage page.

Newer builds and later features locked behind maintenance

PDF-XChange's licence stays valid after maintenance lapses, but you can no longer install newer builds and lose access to features added later. PDFBook's Lifetime tier has no maintenance concept: every feature in the app at purchase stays in the app forever. Pro subscriptions naturally lose Pro features at expiry, but Lifetime is Lifetime.

Windows-only, Mac and Linux users have no path

PDF-XChange Editor is a Windows-only product (with some Wine compatibility on Linux). PDFBook ships native Windows 10/11, macOS 11+ (Apple Silicon and Intel), and Linux (AppImage and .deb) builds. The same $89 Lifetime unlocks any three of those machines.

Powerful editor, but no library tooling

PDF-XChange Editor is a capable editor with serious power-user features. What it doesn't have is a library: no folders, no tags, no reading state across files, no search across your collection. PDFBook is built around the library. Editing is intentionally out of scope.

What users are actually saying

“Support informed me that as of May 2025 they removed access to older installers unless you have an active maintenance agreement. In other words, if you do not keep paying, you lose access to the software entirely unless you happened to back up the installer yourself.”

— Trustpilot: PDF-XChange Co. Ltd

“A perpetual licence is meaningless if the vendor can later deny you access to the software you paid for. This is not what most consumers would reasonably understand a perpetual licence to mean.”

Frequently asked questions

What happened with PDF-XChange in May 2025?+
PDF-XChange Co. Ltd removed download access to older installers for customers whose maintenance had expired. The license key remains valid, but if you need to reinstall the software on a new PC, you can't, unless you happen to have kept a backup of the installer file. The company cites security concerns. Reviewers on Trustpilot and the PDF-XChange forum describe it as a redefinition of what "perpetual license" means.
Wasn't the perpetual license advertised as lifetime?+
Reviewers report yes, the marketing said perpetual / lifetime. The company's defence (per their own Trustpilot replies) is that the EULA only ever promised the license key would work in versions released during the maintenance window, never that installers would remain downloadable. From a user perspective that's a meaningful distinction the marketing copy didn't surface.
Will PDFBook ever do this?+
No. The Lifetime commitment is: the license key keeps working, the installer for your version stays available for download, security patches for your version remain available, and any policy change that would affect Lifetime users gets a 90-day email + manage-page banner before it takes effect. If we ever go out of business, our final build ships with the once-a-day license check disabled so your installed copy keeps working offline forever.
Does PDFBook do PDF editing like PDF-XChange Editor?+
No. PDFBook focuses on reading and library management. PDF-XChange Editor is a genuinely powerful editor. If editing text, pages, forms, and signatures is core to your workflow, keep PDF-XChange (or move to Adobe Acrobat / Foxit). If you mostly read PDFs and want a vendor whose Lifetime promise is durable, PDFBook is the cleaner fit.
Does PDFBook do OCR?+
No. PDFBook does not have OCR. It focuses on reading and organizing PDFs that already contain selectable text. PDF-XChange Editor has built-in OCR (free in the base Editor, with an enhanced engine in Plus), gated by the maintenance issue above.
Can I migrate my PDFs from PDF-XChange?+
Yes. Your PDFs are standard PDF files on disk, and PDF-XChange doesn't lock them in. Point PDFBook at the folder. It indexes them in place without copying or modifying. Your PDF files open as-is; PDFBook reads and organizes them without modifying the file. Note that PDFBook is a reader, not an editor, so it doesn't create or edit in-PDF annotations.
Does PDFBook send my PDFs anywhere?+
No. The desktop app reads PDFs from your folders and stores library metadata in a local JSON file (library.json) under your user data directory. The only outbound call is once-a-day license validation (14-day offline grace) containing the license key and a device fingerprint, never PDF contents, file names, paths, or reading history.
Is PDFBook on Mac and Linux?+
Yes. PDFBook ships native builds for Windows 10/11 (x64), macOS 11+ (Apple Silicon + Intel), and Linux (AppImage and .deb). PDF-XChange Editor is Windows-only, with Wine being the only Linux path.
How many devices does the Lifetime license cover?+
Three. Any mix of Windows, macOS, and Linux. PDF-XChange's single user license can be installed on two of your own machines (primary + secondary); volume packs start at three users.
Refund policy?+
14-day money-back on direct Pro or Lifetime purchases. Email support@pdfbook.app and we process within 5 business days through Stripe.
