Merge PDF: Combine PDFs, Word files and photos into one PDF, in any order. Input: PDF, DOCX, JPG, JPEG, PNG, WEBP, HEIC, HEIF files and values you enter. Output: Results shown on the page and a downloaded file. Privacy: Runs in your browser: inputs and files stay on your device and are not uploaded.
How to merge PDF files
- Drop your files on the box, or tap it to choose them: PDFs, Word documents (.docx) and photos (JPG, PNG, WebP or HEIC from an iPhone). You can add more files at any time.
- Put the files in the order you want with the ↑ and ↓ arrows. Remove any you do not need with ✕.
- Optionally type which pages to take from each PDF, such as
1-3, 5, to combine only parts of documents. Leave it blank to include every page. - Press Merge into PDF and download the combined file. A single Word file or photo on its own is simply converted to PDF.
Private PDF merging
Most online PDF tools upload your documents to their servers, which is a real concern for contracts, bank statements, medical letters and ID documents. This tool runs entirely in your browser: the PDF library is downloaded to your device, and your files are read, combined and saved locally. Nothing is uploaded, there is no file size limit beyond your device's memory, and there are no watermarks or sign-ups.
PDF pages are copied exactly, so text stays selectable and searchable, links and page sizes are preserved, and the quality does not change. Mixed page sizes and orientations are fine: each page keeps its own size. Bookmarks (outlines) and interactive form fields from the original files may not be carried over; fill in forms before merging if you need to keep the answers.
Photos become one page each, fitted on an A4 page or at the photo's own size, the right way up. Word documents are converted on your device with a simplified layout: text stays selectable, and headings, lists, basic tables and images are kept, but fonts, headers, footers and exact page breaks can differ from Word. When the layout must match exactly, save the document as PDF from Word first and merge that PDF.
Common uses include putting a cover letter in front of a CV, combining a filled-in form with photos of receipts for an expense claim, joining scanned pages into one document and assembling chapters for printing.
Example: what a merge keeps
We merged three test PDFs (19 pages, about 10 MB together) in Chrome on a laptop. It took half a second. All 19 pages kept their size, all 32 bookmarks were kept (plus one per file, so you can jump to each document), both internal links still jumped to the right page, and the 6 form fields stayed fillable. In the same test, the command-line tool qpdf dropped the bookmarks and broke the internal links, and Ghostscript dropped the form fields.
A mix of a 10-page PDF, a 3-page Word file and three photos (one an iPhone HEIC, one taken sideways) became one 16-page PDF, with every photo the right way up.

Can I merge Word documents and photos with PDFs?
Yes. Add .docx files, JPG, PNG, WebP or HEIC photos and PDFs in any mix; they are combined in the order of the list. Page ranges apply to PDFs only.
Is there a limit on the number or size of files?
No fixed limit. Dozens of files and hundreds of pages merge fine on a typical computer or phone; very large files depend on your device's memory.
Can I merge password-protected PDFs?
Not directly. Open the file in a PDF reader with the password and save or print a copy without protection, then merge that copy.
Will the merged PDF lose quality?
PDF pages are copied as they are, without re-compressing text or images. Photos are stored at full resolution as high-quality JPEG (PNG stays PNG).
Does merging keep bookmarks, links and fillable forms?
Yes. Bookmarks are kept and grouped per file, links inside a document still point to the right page, and form fields stay fillable.
