Merge PDF Files Online — Fast and Simple

PDFMadeSimple's PDF merger lets you combine any number of PDF files into a single document in seconds, directly in your browser. No software to install, no account needed to get started. Upload your PDFs, merge them and download the result immediately.

Whether you're combining chapters of a report, joining multiple invoices into one file, or assembling a portfolio from separate PDFs, our merger handles it quickly and cleanly. Every page from every file is included in the output, in the order you specify.

Why Merge PDF Files?

Sending multiple PDF files can be inconvenient for both sender and recipient. A single merged PDF is easier to email, simpler to file, and more professional to share. Merging is also essential when a system or portal requires a single document upload rather than multiple separate files.

Common reasons to merge PDF files include:

  • Combining a CV and cover letter into one document for a job application
  • Joining multiple invoices into a single monthly statement
  • Assembling a report from chapters saved as separate PDF files
  • Combining scanned pages from a multi-page document into one file
  • Merging contracts, appendices and attachments for a client submission
  • Creating a single PDF portfolio from separate image or document PDFs

Quality Is Preserved When Merging

Merging PDFs with PDFMadeSimple does not reduce the quality of any content. Text remains sharp, images retain their resolution, and the formatting of every page is preserved exactly as it appears in the original files. The merged PDF is simply a combination of your originals — nothing is re-processed or compressed.

Merge PDFs with Different Page Sizes

Our merger fully supports PDFs with different page sizes, orientations and content types. A landscape spreadsheet can be merged with portrait text pages, and each page will retain its original size and orientation in the combined document. There's no requirement for all files to match.

Is It Safe to Upload My PDF Files?

All files uploaded to PDFMadeSimple are transferred over SSL encrypted connections. Once your merged PDF has been created, all original files and the merged document are permanently deleted from our servers within 24 hours.

We are fully GDPR compliant. We do not read, store or share your documents with any third party.

Merge PDF on Any Device

PDFMadeSimple works in any modern browser on any device. Whether you're on a Windows PC, a MacBook, an iPhone or an Android tablet, the merger works identically on all platforms. No app to install — just open the page, upload your files and download your merged PDF.
