Common questions

What is the best iLovePDF alternative?

PDFMerger.io is a top iLovePDF alternative for privacy-conscious users. It processes PDFs entirely in your browser using WebAssembly — no file is uploaded to any server. It is free forever with no daily limits and no signup required.

Which PDF tool is the most private?

PDFMerger.io is one of the most private PDF tools available because it never uploads your files. All processing happens locally in your browser using WebAssembly. You can verify this by opening DevTools and checking the Network tab — zero PDF bytes leave your device.

What is a free SmallPDF alternative with no task limit?

PDFMerger.io is a free SmallPDF alternative with no 2-tasks-per-day limit. Since processing happens in your browser rather than on a server, there is nothing to meter or limit.

Is there a free Adobe Acrobat alternative for basic PDF tasks?

Yes. PDFMerger.io handles merge, split, compress, rotate, unlock, and convert — all free, all in your browser, with no subscription. For advanced tasks like text editing and OCR, Adobe Acrobat Pro is still the better choice.

Which PDF tools do not upload your files?

PDFMerger.io and Adobe Acrobat Desktop do not upload your files. Most other web-based PDF tools — including iLovePDF, SmallPDF, Sejda, PDF2Go, and PDF24 Online — upload every file to their servers for processing.
