Merge PDF
Combine multiple PDFs into a single file?private and offline. Upload, reorder, and download instantly.
Explanation
Dexify merges PDFs locally with PDF-Lib. Upload multiple files, set their order, and export a clean, watermark-free PDF. Because everything runs in your browser, documents never leave your device.
Use the list controls to reorder or remove files before merging. Mixed page sizes are preserved, and output stays in original quality. Status and size indicators keep you oriented while the merge runs.
The interface mirrors other Dexify tools—chips, upload area, and consistent buttons—so switching between merge, compress, or protect feels seamless.
Frequently Asked Questions
Are files uploaded?
No. Merging happens in your browser; PDFs never leave your device.
How is order set?
Files follow the order shown. Use the up/down buttons in the list to reorder.
How many files can I merge?
Recommended up to ~20 files; large batches depend on device memory.
Do signatures/forms stay?
