Combine two or more PDFs into a single document, arranged exactly how you want. Everything happens in your browser.
Your PDFs are processed locally in your browser and are never uploaded.
Very large documents may be limited by your device's available memory.
How it works
Drop two or more PDF files into the box above. Each file shows its size and page count so you know exactly what you're combining.
Drag files into position, or use the up/down buttons — the merged document follows your list from top to bottom.
Click Merge PDFs. Your browser assembles the combined file — pages keep their original size, orientation, and quality.
Why PixSquash
Most PDF mergers upload your documents to a server. This one can't — the merge runs entirely on your device using the pdf-lib engine. That makes it safe for contracts, invoices, IDs, medical records, and anything else you'd rather keep to yourself.
Skipping the upload isn't just private — it's faster. Merges complete in seconds because your files never travel anywhere.
Pages are copied, not re-rendered. Text stays sharp and selectable; nothing is converted into images.
Combine scanned pages into one document, assemble reports from chapters, join invoices for accounting, or merge application paperwork into a single file.
FAQ
Drop two or more PDFs above, arrange them in order, and click Merge PDFs. The combined file downloads instantly — free, no signup, no watermark.
No. The entire merge happens locally in your browser. Your documents never leave your device — you can verify by loading this page and then disconnecting from the internet.
Yes — drag files into position or use the accessible up/down buttons. The merged PDF follows exactly the order shown in your list.
No fixed limit, but because processing happens on your device, very large documents are constrained by browser memory. Everyday PDFs merge in seconds.
Encrypted PDFs can't be merged directly — the tool flags them with a clear message so you can unlock them first and try again.
