What Is PDF Merging?
PDF merging combines multiple PDF files into a single document in one click. Common use cases include submitting multiple documents as one attachment - job applications, grant submissions, and university enrolments often require a single file - creating combined reports from separate sections, archiving related documents together for long-term storage, and printing multiple files in sequence without switching between documents. The merged PDF maintains the original quality of each source document: images, fonts, and formatting are preserved exactly. Page order in the merged file follows the upload order, so you can drag and reorder files before merging to control exactly which pages appear first.
Why It Matters
Email attachments are often limited to a fixed size or count per message. Many institutions - HR departments, universities, and government agencies - explicitly require 'one file only' submissions. Sending five attachments when the form expects one can result in rejection or a request to resubmit. Merging beforehand also makes it easier for the recipient: one file to open, one file to print, and no confusion about which attachment is which. Print shops also strongly prefer single files for multi-page print jobs to avoid page-order errors.
