Merge PDF FAQ
Will my original PDF be changed?
No. Your original file stays unchanged. Download the result as a separate file.
Can I merge only some pages of a PDF?
Yes. Type a range such as “1-3, 7” under any file and only those pages are merged, in that order.
How many PDFs can I merge at once?
There is no fixed limit. Hundreds of pages merge in seconds on a modern laptop; phones handle smaller jobs comfortably.
Is there a file size or daily limit?
No daily limit, no signup and no watermark. Files can be up to 200 MB each; very large documents depend on your device’s memory.
