Just a browser. No software installation, no account, no watermark on the output file. ihatepdf's merge tool runs entirely in your browser — your files never leave your device.
How to merge PDFs in under 2 minutes
- Go to ihatepdf.cv/merge-pdf — no sign-up required.
- Upload your PDF files — click Select PDFs or drag and drop. Add as many files as you need.
- Drag to reorder — drag the thumbnails into the final page order.
- Click Merge PDFs — processing takes a few seconds locally in your browser.
- Download — the combined PDF downloads with no watermark.
How to merge PDFs on Mac
On Mac you can also use Preview: open the first PDF, go to View → Thumbnails, then drag other PDFs into the sidebar. This works fine for basic merging but you need all the files on your Mac already and you have to save manually. For a faster solution that works on any OS without installing anything, ihatepdf's merger is the quickest option.
How to merge PDFs on Windows
Windows doesn't have a built-in PDF merger. The quickest approach is using a browser-based tool — open ihatepdf.cv/merge-pdf in Chrome, Edge, or Firefox, upload your files, and download the merged result. No software installation needed.
How to merge PDFs on iPhone or Android
ihatepdf works on mobile browsers too. Open the tool in Safari or Chrome on your phone, tap to upload from your Files app or Google Drive, reorder the pages, and download. The merged file saves directly to your phone.
What to do if the merged PDF is too large
After merging, if the file size is too large to email or upload, run it through ihatepdf's compressor. Medium compression typically reduces a merged PDF by 40–50% with no visible quality loss.
