Merge PDF Files into One
Merge multiple PDF files into one online, in the order you choose.
How to use Merge PDF
Add two or more PDFs, drag the file rows into the order you want, and merge. Every page, its size and its rotation are copied exactly as-is — nothing is re-rendered, so text stays selectable and quality is untouched no matter how many files you combine.
- Drop your files into the box above, or click it to browse. You can also paste from the clipboard.
- Adjust the options to taste — the defaults are sensible for most cases.
- Press Merge and watch the progress bar; everything runs on your device.
- Download your result — individually, or as a ZIP when there are several files.
Like every tool on ImageCompressorKits, this runs 100% in your browser: your file is never uploaded to any server, which makes it safe to use even with private documents — and it keeps working if you go offline after the page loads.
Frequently asked questions
Is there a size or file count limit?
No fixed limit. Merging is memory-light because pages are copied, not re-rendered — dozens of files and hundreds of pages are routine.
Will merging reduce quality or break links?
Quality is identical because pages are copied directly. Internal links between merged documents aren't rewritten, but each document's own pages stay intact.
Is this tool really free?
Yes — completely free, with no signup, no watermark, and no file limits beyond what your device's memory can handle.
Are my files private?
Yes. Processing happens locally in your browser via JavaScript; nothing is transmitted or stored. See our privacy policy for the full picture.
