Frequently asked questions

Are my PDF files uploaded to a server?
No. FeatherPDF merges your PDFs entirely in your browser using your own device. Your files never leave your computer and are never uploaded to us.
Is there a file size or number-of-files limit?
There is no hard limit. Because everything runs locally, the only limit is your device's memory. Very large files may be slower on low-memory devices.
Does it cost anything or require an account?
No. Merging PDFs is free and requires no sign-up or account.
Can I reorder the PDFs before merging?
Yes. After adding your files, reorder them with the up and down controls, and remove any you don't want, before merging.
