The Easiest Way to Combine PDF Files
When you are managing a project, applying for a job, or compiling research, you often end up with multiple PDF files that belong together. Sending them as separate email attachments is messy and confusing for the recipient. heyPDF provides a simple, lightning-fast tool to combine PDF files into a single, cohesive document that is easy to read, print, and share.
How to Join PDFs Together
Combining files shouldn't require reading a manual. With heyPDF, you simply drag and drop all your PDFs into the browser window. Our interface shows you visual thumbnails of every file you've uploaded. You can easily click and drag these thumbnails to arrange them in the exact sequence you want them to appear in the combined document. Once everything is in order, one click stitches them together perfectly.
Combine PDFs and Images Seamlessly
Sometimes you need to combine more than just PDFs. Perhaps you have a scanned receipt (JPG) or a screenshot (PNG) that needs to be appended to an expense report PDF. heyPDF allows you to combine image files alongside your PDFs. Just drop the images into the workspace, place them in the correct order, and the tool will automatically convert them to PDF pages as it joins everything together.
Secure Document Combining
We treat your documents with the utmost respect for privacy. When you combine PDF files on heyPDF, the data is encrypted during upload and download using 256-bit SSL. The files are processed on secure cloud servers and are never read or analyzed by humans. To ensure complete confidentiality, all files (both your original uploads and the combined output) are automatically and permanently deleted from our systems after exactly 2 hours.
No Watermarks, No Tricks
Many online tools claim to let you combine PDF files for free, only to stamp a massive watermark on your final document. heyPDF is different. We never add watermarks to your combined files. The document you download is clean, professional, and ready for immediate use in any business or academic setting.
