Frequently Asked Questions

- Is there a limit to how many PDFs I can merge?
- You can merge as many PDFs as you need. Since the processing happens on your computer, the limit is based on your device's memory. For best performance, we recommend merging batches of files under 100MB total.
- Can I reorder the pages before merging?
