PDFBook vs iLovePDF

iLovePDF is great for quick edits.PDFBook is for reading and keeping your library.

iLovePDF is a fast online toolkit for merging, splitting, converting, and compressing PDFs, and it's good at that. But the web flow uploads your files to its servers, and the free tier has daily-task and file-size limits plus ads. PDFBook is a different tool: a local-first PDF reader and library for Windows, macOS, and Linux that never uploads your files. Use iLovePDF for one-off utilities. Use PDFBook for daily reading and organising hundreds of PDFs. $6.99/mo, $29.99/yr, or $89 once for Lifetime.

Why people leave iLovePDF

Common frustrations with iLovePDF from public reviews, and how PDFBook solves each.

iLovePDF's web tools upload your PDFs to its servers

Every iLovePDF web task sends your file to iLovePDF's processing servers. They delete files automatically after processing, but the upload still happens. For non-sensitive documents that's fine. For legal records, financial statements, unreleased research, or anything with PII, uploading to any third-party server is the structural concern. PDFBook reads PDFs locally from your own folders and never uploads them.

Free tier: daily task limits, file-size caps, and ads

iLovePDF's free web account limits how many tasks you can run per day, caps file sizes (for example image-to-PDF around 40 MB and most conversions around 100 MB as of June 2026), withholds OCR, and shows ads while you work. PDFBook Free is capped at 50 books in your library, but has no per-file size limit, no page cap, and no ads, open a 1,000-page scripture or a 500 MB scan locally, limited only by your device's memory.

It's a utility, not a reader or a library

iLovePDF is built around tasks: drop a file, pick a tool, download the result. It has no library, no reading modes, no per-book notes, once a file is processed, you're done. PDFBook is a reading and library tool: folders, tags, ratings, reading state, bookmarks, table of contents, and search across your whole collection by title, author, tag, and path.

The unlimited, offline experience needs Premium

To remove ads, lift the daily and file-size limits, unlock OCR and batch processing, and use the desktop/mobile apps fully, you subscribe to iLovePDF Premium (roughly $4–$7/month region-dependent, as of June 2026). PDFBook offers a one-time Lifetime at $89, no renewal, no "upgrade or the limits come back."

Frequently asked questions

Is PDFBook a replacement for iLovePDF?+
Not exactly, they do different jobs. iLovePDF is a utility for one-off tasks like merging, converting, compressing, OCR, and signing. PDFBook is a reader and library: it organises your PDF collection and gives you book-like reading modes. Many people will keep iLovePDF for occasional edits and use PDFBook for daily reading. PDFBook is not a PDF editor and not an OCR or signature tool.
What does iLovePDF do that PDFBook doesn't?+
Quite a lot on the utility side: a wide range of two-way conversions (PDF↔Word/Excel/PowerPoint/JPG), OCR, compression, in-PDF annotation and e-signatures, plus native iOS and Android apps and a browser-based web flow. If those are your main needs, iLovePDF is the better fit. PDFBook focuses on reading and library management instead.
Does iLovePDF upload my files?+
Its web tools do, your file is sent to iLovePDF's servers for processing and then auto-deleted. iLovePDF also offers a desktop app (Windows and macOS) that processes files offline. PDFBook never uploads your PDFs at all. The desktop app and the browser-based Web Reader both keep files on your machine.
How much does each cost?+
iLovePDF has a free web tier (with daily-task and file-size limits, no OCR, and ads) and a Premium subscription around $4–$7/month depending on region, as of June 2026; Business is custom-priced. PDFBook is free up to 50 books, then $6.99/month or $29.99/year for Pro, or $89 once for Lifetime with no renewal.
Can PDFBook convert files like iLovePDF?+
Only in one direction, and to PDF. PDFBook's built-in Converter turns EPUB, KEPUB, MOBI, AZW, AZW3, KF8, DOCX, Markdown, TXT, HTML, CBZ, and CBR into PDF, all on-device. It does not convert PDF back to Word/Excel, and it does not do OCR. The converter also skips DRM-protected files. It never removes DRM. For two-way Office conversions or OCR, iLovePDF is the right tool.
What's PDFBook's refund policy?+
14 days, no questions asked, on Pro or Lifetime. Email support@pdfbook.app and we process the refund within 5 business days through Stripe.
