    Common Use Cases for PDF Merging

    Merge vs. Combine: What's the Difference?

    How PDF Merging Works

    When you merge PDF files, our tool preserves all original content including text, images, vector graphics, embedded fonts, annotations, form fields, and bookmarks. The final PDF maintains the exact formatting of each source document. For files under 20MB total, merging happens directly in your browser for maximum privacy. Larger files are processed on our secure servers with TLS encryption and automatically deleted within 60 minutes.

    Technical Specifications

    Maximum file size: 50MB per PDF. No limit on number of files to merge (performance may vary with very large numbers). Supports all PDF versions from 1.4 through 2.0. The merged PDF is compatible with all PDF readers including Adobe Acrobat, Preview, and web browsers.

    Privacy & Security

    Your PDFs are never stored permanently. Small files (under 20MB total) are merged entirely in your browser — your files never leave your device. Larger files are processed on our servers and automatically deleted within 60 minutes. We do not access, view, or analyze your document content beyond the merging process. No personal information is collected or required to use this tool.
