Frequently Asked Questions
Q: How many PDFs can I merge at once? As many as you want. The only limit is your device's memory.
Q: Will merging PDFs reduce quality? No. The PDF content is preserved exactly — images, text, fonts, and formatting remain intact.
Q: Can I merge password-protected PDFs? No. Password-protected PDFs need to be unlocked first.
Q: What's the maximum file size? Since processing happens in your browser, very large files (500MB+) may be slow depending on your device.
