What Is PDF Merging?
PDF merging combines multiple PDF documents into a single file. Instead of sending several attachments or switching between files, you get one consolidated document. Common use cases include combining scanned receipts, merging report sections, assembling contracts, or creating a single portfolio from multiple documents.
This tool runs entirely in your browser. Your PDFs are never uploaded to a server — they stay on your device. You control the order of files before merging and can reorder them with up/down buttons.
When to Merge PDFs
Merge PDFs when you need to submit one document instead of many (e.g., job applications, grant proposals, or tax documents). Combine scanned pages from multiple scans into one file. Assemble reports from different sources. Create a single handout or manual from multiple chapters.
Merging preserves the visual appearance of each page. The output order matches the order you specify. You can merge PDFs of different sizes and orientations — each page keeps its original dimensions.
Privacy and Security
Because all processing happens locally in your browser, your PDFs never leave your computer. No server receives, stores, or processes your files. This makes the tool suitable for sensitive documents like contracts, financial records, or personal identification.
There is no account required and no data retention. Once you close the tab or clear the page, no trace of your files remains on any server.
