Privacy: Why No-Upload PDF Mergers Matter
Many PDF tools (Smallpdf, ILovePDF, Adobe Online) upload your files to their servers for processing. This is a privacy risk for sensitive documents like bank statements, tax returns, legal contracts, medical records, and HR documents. Formly's PDF merger uses pdf-lib running entirely in your browser — your documents never leave your device. This makes it the safest choice for confidential files.
Formly vs Smallpdf vs ILovePDF
Smallpdf: 2 free tasks per hour, requires sign-up for more, uploads files to servers. ILovePDF: 5 free tasks, files uploaded to cloud. Adobe Acrobat Online: subscription required for most features. Formly: unlimited free merges, no upload, no account required, works offline after page load. For privacy-conscious users and those with sensitive documents, Formly is the clear choice.
