Combine any number of PDF files into a single document — free, with no server upload and no watermark. Drag and drop to set the order, click Merge, and download instantly. All processing runs entirely in your browser using WebAssembly, so your files never leave your device even for a millisecond.
Most PDF merging services — ilovepdf, smallpdf, Adobe Acrobat online — upload your documents to their servers before combining them. For confidential files like contracts, legal documents, financial records, or personal CVs, this creates an unnecessary privacy risk. ihatepdf runs the entire merge operation locally using pdf-lib compiled to WebAssembly. The bytes of your documents never travel over the network. Once the ihatepdf page has loaded, you can even disconnect your internet connection and the tool will still merge PDFs perfectly.
Merging PDFs is one of the most common document tasks in professional life. Combine multiple bank statements into one file for a loan application. Merge separate chapters into a complete report. Combine a CV with a cover letter and portfolio into a single PDF for a job application. Combine invoices for monthly expense submissions. Join scanned pages that were saved as individual files. ihatepdf handles all of these instantly, with no file size limit and no watermark on the output.
Use Merge PDF when you have two or more separate PDF files you want to combine into one. Use Organize Pages when you have a single PDF and want to reorder, rotate, or delete individual pages within it. You can combine both tools: organize each individual file first to get the page order right, then merge them all together in the final sequence you need.
No artificial limit. Merge as many PDFs as your device memory allows — typically 20–50 files on a desktop browser.
No. Merging happens entirely in your browser using pdf-lib via WebAssembly. Your files never leave your device.
Never. ihatepdf does not add any watermark to merged or any other output file.
You need to remove the password first using the Remove Password tool, then merge, then re-encrypt if needed.
Yes. Pages appear in the exact sequence you arrange the thumbnails before merging.
Yes. The tool works in any modern mobile browser (Chrome, Safari, Firefox) on Android and iPhone with no app installation.
No server limit. The practical limit is your device RAM — typically up to 150MB total across all files on a desktop.
You can reorder entire PDF documents by dragging their thumbnails. For individual page reordering, use the Organize Pages tool first, then merge.
