We read every message. Whether you have a question about how NanoPDF works, found a bug, or want to suggest a new tool — we'd like to hear from you.
We aim to reply within a few business days. Please include your browser and device type if you're reporting a technical issue — it helps us reproduce the problem faster.
What we can help with
- How client-side PDF merging works
- Bug reports or unexpected behavior
- Feature requests for upcoming tools
- Privacy and data-handling questions (see also our Privacy Policy)
- Partnership or press inquiries
What we cannot help with
Because files are processed locally in your browser, we do not have access to your documents and cannot recover, repair, or retrieve files on your behalf. If a merge fails, try with smaller files, a different browser, or ensure PDFs are not password-protected.
