How to merge PDF
- Drop two or more PDFs, or add them one at a time.
- Drag the files into the order you want them to appear.
- Press Merge and download the combined document.
What happens to your file
Pages are appended in your order, exactly as they are: page sizes, rotations, text layers, links and annotations come through untouched.
Fonts embedded in each source stay embedded, so nothing is re-flowed or substituted. The result is usually about the sum of the inputs.
Encrypted sources are refused rather than silently skipped — unlock them first.
Questions
How many PDFs can I merge at once?
Ten per merge. For more, merge in two rounds — the output of the first is a normal PDF.
Can I change the order after dropping the files?
Yes. Drag the cards into place, or use the arrows on each card with a keyboard. The order on screen is the order in the file.
Do bookmarks and links survive?
Links inside pages do. Bookmark outlines from each source are kept where the source had them.
Can I merge pages from the middle of a document?
Split it first with the Split PDF tool, then merge the parts you want.
Do it once, not on every form
Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
