Does merging keep the quality?
Yes. The pages of your PDFs are copied into the merged file as they are, not turned into images, so text stays sharp and can still be selected and copied. JPG and PNG images are each placed on an A4 page.
A few special cases:
| File type | What happens |
|---|---|
| Edit-protected PDF that opens without a password | Can be merged, its pages are added as images |
| PDF that needs a password to open | Cannot be merged, unlock it first |
| PDF with a digital signature | Can be merged, but the signature is no longer valid in the merged file |
Is it safe to merge PDFs online?
Your files are read and merged inside your browser. They are not uploaded to a server, and they are gone when you close the page. That makes it a good fit for personal files, contracts and financial documents.
