Combining PDFs into a single document has never been easier. This tool lets you take multiple separate PDF files and join them into one cohesive document. Perfect for when you have documents scattered across different files that logically belong together. The process is straightforward: select your files, arrange them in the desired order, and combine. Everything happens right in your browser, which means your documents remain completely private. No cloud uploads, no server processing, just pure local file handling. The result is a seamlessly merged PDF that looks like it was always a single document.

## How it works

1. **Upload Files** — Drag and drop or click to select multiple PDF files from your device
2. **Arrange Order** — Reorder files by dragging them into your preferred sequence
3. **Merge & Download** — Click merge and download your combined PDF instantly

## Use cases

## Tips

- **Standardize Page Orientation**: Check that all PDFs have consistent portrait or landscape orientation before combining for a cleaner result.
- **Review Total Size**: Before combining, note the total size of all files to ensure the final PDF will be manageable.
- **Group by Section**: When combining many files, arrange them logically by section or topic for easier navigation.
- **Use Meaningful Filenames**: The order files appear may default to alphabetical, so name files appropriately before uploading.
