About this tool
Combine scanned pages, application documents, or signed forms into one PDF. Drag the files into the required order before downloading.
Pages are copied without re-rendering or recompression. Text, fonts, images, and page sizes are preserved. The documents stay in the browser during the merge.
How to use it
- Add two or more PDF files.
- Drag the files into the order the final document should read.
- Untick any file you decide to leave out; no need to remove and re-add.
- Click Download PDF to save the combined document.
Tips
- Get the file order right before merging; dragging whole files into place is much easier than reordering individual pages afterwards.
- After merging, skim the result once and prune stray blank pages or duplicate cover sheets with the page editor.
- Merging filled-in forms can behave oddly (form fields with the same name interact); if a form misbehaves after merging, print-to-PDF each form first and merge those flattened copies.
FAQs
Is there a limit on how many PDFs I can merge?
No fixed limit; practical capacity depends on your device's memory, since everything runs locally. Dozens of typical documents merge without trouble.
Will the merged PDF keep the original quality?
Yes. Pages are transplanted, not re-rendered; text stays sharp and images keep their original compression.
Do bookmarks and links survive the merge?
Page content always survives. Document-level extras like the bookmark sidebar may not carry over, and links that jump to a page number can land on the wrong page after merging; check them if they matter.
Can I mix page sizes and orientations?
Yes. Each page keeps its own dimensions; PDF handles mixed A4, Letter, portrait, and landscape pages in one file natively.
Are my documents uploaded to merge them?
No. The files are combined by your browser on your device; nothing is sent to a server.
