About this tool

Merge PDF joins several PDF documents into a single file, in the order you choose. Pages keep their original size, orientation and content — nothing is re-rendered or re-compressed, so text stays selectable and quality stays identical.

Merging does not remove passwords: encrypted files must be unlocked first. Interactive form fields and some annotations may not survive the merge, and bookmarks from the source files are not carried over in this version.

Privacy

This tool runs entirely in your browser. Your file is read from disk by the page, processed with WebAssembly and JavaScript on your device, and the result is created locally. Nothing is uploaded to a PDFYoga server.

FAQ

Is there a limit on how many PDFs I can merge?
There is no fixed count limit. The practical limit is memory: very large documents combined together can exhaust what the browser tab is allowed to use.
Does merging reduce quality?
No. Pages are copied as-is, so images, fonts and text remain exactly as they were in the source files.
Can I merge a password-protected PDF?
Not directly. Remove the password first with Unlock PDF, then merge the unprotected copy.
Can I merge on my phone?
Yes, on any modern mobile browser. Keep the combined size under about 100 MB on mobile for reliable results.
