Our PDF merge tool supports combining up to 50 files at once. Simply drag and drop your documents into the upload area or click to browse your local files. The tool preserves bookmarks, links, and form fields from all source documents.
Files are processed entirely in your browser using WebAssembly. No data is uploaded to any server, ensuring complete privacy for sensitive documents. The merge operation typically completes in under 3 seconds for files totaling less than 100 MB.
Advanced options include page range selection for each input file, the ability to interleave pages from alternating documents, and automatic table of contents generation based on source file names.
The resulting PDF maintains the highest quality settings from the input files. Metadata such as author, title, and keywords can be customized before downloading the final merged document.
