iLovePDF is one of the most popular PDF sites on the web, and for good reason: it covers a lot of tasks and the free tier is genuinely usable. But it's not the right fit for everyone — common reasons people look for an alternative are the upload-based processing (your files go to their servers), the daily task limits and file-size caps on the free tier, and the account prompts. Here are five alternatives and where each one shines.
1. pdfia — best for privacy (nothing is uploaded)
pdfia takes a fundamentally different approach: every tool runs inside your browser using WebAssembly, so your files never leave your device — there's no upload, which also means no watermarks, no sign-up, and no practical file-size limit. It covers the everyday operations: merge, split,compress, rotate,watermark, PDF to JPG,JPG to PDF, and more. It's also the only option here with afree API and MCP server, so AI assistants like Claude can use the tools directly. The trade-off: no PDF↔Word/Excel conversion, since faithful Office conversion still requires server-side software.
2. Smallpdf — best polish, similar model to iLovePDF
Smallpdf is iLovePDF's closest competitor: a clean interface, wide tool coverage including Office conversions, and mobile apps. Like iLovePDF, processing happens on their servers and the free tier is limited (daily task caps, sign-in prompts); the Pro subscription removes the limits. If you're leaving iLovePDF because of the upload model or the caps, Smallpdf won't change much — if you just want a different interface with similar breadth, it's a solid pick.
3. PDF24 — best free desktop suite (Windows)
PDF24 offers a genuinely free, ad-supported set of tools with both a web version and a Windows desktop app. The desktop app processes files locally on your PC, which solves the privacy problem, and the feature list is long. Downsides: Windows-only for the offline app, a dated interface, and the web version still uploads like the others.
4. LibreOffice Draw / macOS Preview — best built-in options
For light editing you may not need a website at all. macOS Preview merges, reorders, rotates, and annotates PDFs out of the box. On any platform, the free LibreOffice suite can edit PDF content directly. Neither is convenient for batch work, but they're completely offline and already installed (or free to install).
5. Stirling PDF — best for self-hosters
Stirling PDF is an open-source, self-hosted PDF toolbox you run in Docker on your own server. It has an enormous feature list and total data control — but "install Docker and maintain a server" is the price of admission. Great for homelab users and companies; overkill for everyone else.

Which should you pick?
If your main need is everyday PDF tasks — merging, splitting, compressing, converting to and from images — and you'd rather your documents never touch someone else's server,pdfia is the simplest switch: open a tool, drop a file, done. If you specifically need PDF-to-Word with perfect formatting, a server-based service like iLovePDF or Smallpdf is still the pragmatic choice — just avoid uploading anything sensitive.
