Tips
- All processing happens locally — no files leave your device.
- Drag files into any order before merging using the ↑ ↓ buttons.
- Each file is limited to 50 MB. For larger PDFs, consider compressing them first.
- Encrypted or password-protected PDFs may fail to merge.
- The merged output preserves the original page dimensions of each source PDF.
