FAQ
Are PDFs uploaded to your servers?
No. Selected PDFs are processed only in the browser and are not sent to our servers.
Can I reorder files when merging PDFs?
Yes. After loading two files in the merge panel, swap their order before downloading.
Can I split a PDF at a chosen page?
Yes. After the page count loads, enter the last page of the first part. For 10 pages with 3, you get pages 1–3 and 4–10.
Do password-protected PDFs work?
Encrypted PDFs may fail. Large files depend on device memory—try a smaller file or another device if needed.
Can I merge PDFs on my phone?
Yes, via mobile browsers. Very large PDFs may need more memory—prefer a computer for heavy files.
Is it free with no signup and no usage limit?
Yes. No signup or install required. Extremely large files may still be limited by device performance.
