Frequently Asked Questions — Merge PDF
How many PDF files can I merge at once?
You can merge up to 10 PDF files into a single document in one operation. If you have more files, simply repeat the process by merging the output with additional PDFs. There are no daily limits.
Will merging PDFs affect the formatting or quality?
Not at all. Docsly merges the raw PDF page streams without re-rendering or re-compressing. All fonts, images, hyperlinks, form fields, and bookmarks are preserved exactly as they appear in the original files.
Can I rearrange pages before merging?
Yes. After uploading your files, you can drag the file thumbnails to rearrange the order. The final merged PDF follows the sequence you set, allowing full control over the page flow of your document.
Can I merge PDFs with different page sizes?
Absolutely. Docsly preserves the original page dimensions of each file. If one PDF has A4 pages and another has Letter-size pages, both will appear in their native sizes within the merged output.
Is the Docsly Merge PDF tool really free?
Yes — 100 % free with no hidden limits, no watermarks, and no account required. Docsly is ad-supported, which allows us to offer all tools at zero cost to you.
