What is a Combinar PDF?
Merging is what you need when a document has been split across separate PDF exports — a signed cover page from one system, scanned attachments from another — and you need to hand over one file instead of several. Order matters: pages come out in exactly the sequence you add the files in, so arrange them in reading order before merging.
How to use the Combinar PDF
- Add two or more PDF files, in the order you want them
- Use the up/down arrows to reorder them if needed
- Download the combined PDF, merged instantly on your device
Example
Merging a 2-page cover letter with a 10-page resume and a 3-page reference list, in that order, produces one 15-page PDF — nothing is renumbered or reflowed, each source file's pages just appear back to back.
Why use Combinar PDF
Reorder before you merge
Added a file out of order? Move it earlier or later with the up/down arrows — the final page order always matches what's shown before you click merge.
No page or file-count limit
Merge as many PDFs as you need in one pass, each keeping its original fonts, images, and formatting — nothing is re-rendered or flattened.
Nothing uploaded
Merging runs entirely in your browser via WebAssembly, so your files never leave your device — no waiting on an upload, no server-side copy to worry about.
What can you create?
Combine scanned pages
Turn separate single-page scans from a flatbed scanner into one multi-page document, in the order you scanned them.
Build an application packet
Merge a cover letter, resume, and references into the single PDF most job portals expect.
Assemble a finished report
Combine a title page, body chapters, and an appendix exported separately from different tools into one final file.
Frequently asked questions
Is my PDF uploaded anywhere?
No — Combinar PDF runs entirely in your browser using JavaScript/WebAssembly. Your PDF is never sent to a server.
Is there a file size limit?
Free use covers files up to 100MB per file; signing up for Pro raises that to 500MB.
Are bookmarks, links, and form fields preserved after merging?
Yes — each source PDF's internal structure (bookmarks, hyperlinks, form fields) carries over into the merged file; only the page order changes.
Can I merge a PDF that's password-protected?
Not directly — unlock it first with Unlock PDF, then merge the unlocked copy. A locked PDF can't be read to extract its pages.
Does it matter what order I select the files in my file picker?
No — files are added to the merge queue in the order the picker returns them, but you can use the up/down arrows to reorder that queue afterward before merging, independent of how you originally selected them.
