PDF merging combines two or more separate PDF files into a single document. The pages from each file are appended in sequence, creating one continuous PDF. This is essential for assembling reports, combining scanned documents, packaging multiple invoices, or creating unified document sets for submission.
Many workflows require submitting a single document — loan applications, grant proposals, legal filings, and college admissions. Rather than asking recipients to open multiple files, a merged PDF provides a clean, professional package. It also simplifies document management and archival.
Drop multiple PDF files onto the page and drag to reorder them. Convertful uses pdf-lib to read each file, extract all pages, and assemble them into a new PDF in your chosen order. All formatting, links, annotations, and bookmarks are preserved. Processing happens entirely in your browser.
Absolutely. Your PDFs never leave your device. There is no server upload and no cloud storage. Convertful cannot see, access, or store your documents.
Files are merged in the order you add them. Add them in the sequence you want for the final document.
You can merge up to 20 PDFs at once, completely free. No daily limits or restrictions.
Page content, embedded fonts, images, and page-level annotations (including link annotations that point within the same page) are all carried over. Document-level outline bookmarks and AcroForm field state are not copied — if you rely on bookmarks or fillable forms, merge-and-fill separately or keep the source PDFs. Hyperlinks that target a page in a different source PDF will not be remapped and may break.
