How it compares

Smallpdf and iLovePDF offer similar merging but limit free-tier usage to 2 files per day and upload your PDFs to their servers. Freemergepdf has no usage cap and never uploads. For basic merging, Freemergepdf is faster and more private. For advanced features like OCR or compression, Smallpdf has the broader feature set.

Privacy

PDFs never leave your browser. All merging happens client-side using JavaScript. No upload, no server storage.
