Merge PDF files into one document
Merge multiple PDF files in your browser. Reorder files, select page ranges and download a new combined document.
1. Add and arrange files
2. Prepare your PDF
For photos, each JPG/PNG becomes one centered A4 page. Max 25 megapixels per image. Transparent PNGs use a white page.
Elements are added as a transparent image layer to the pages selected in the file list. The underlying text remains. A white box is not secure redaction. New text is not selectable; existing PDF content stays underneath.
Check the output before using it. Text extraction uses selectable text only; scanned pages need OCR. It does not compress or edit existing text.
How to use this tool
Files are processed from top to bottom. Set a separate page range for each file: 1-3,5 includes only those pages. Repeating a page number duplicates it in the output. Your originals stay unchanged. Do not use encrypted or signed PDFs; preservation of forms, attachments and bookmarks is not guaranteed.
- Choose your PDF files.
- Arrange files and enter a page range for each file if needed.
- Prepare, download and check the output in your own viewer.
Up to 20 input files, 20 MB each and 80 MB total. PDF output: up to 500 pages/100 MB; image ZIP: up to 100 pages/100 MB. Encrypted or signed input is unsupported. Forms, attachments and bookmarks may not survive.
