How PDF Merger works
PDF Merger combines selected PDF files in the order shown by the file picker. It accepts 2–20 unlocked PDFs, up to 25 MB each, and downloads one merged copy; the originals stay unchanged.
Example: prepare an application on Android
Select the cover letter first, then the resume and certificates in the order required. Merge, open the download from the browser Downloads area, and check that every page is upright and readable before uploading. A portal may require separate files, so follow its instructions.
PDF Merger questions
Why did a file fail to merge?
Check that each item is a valid, unlocked PDF below 25 MB. Some damaged or unusual PDFs may not open in the browser library.
Can I change the page order?
The output follows the selected file order. Choose files in the order you want before merging, then inspect the downloaded document.
