Combine PDFs without uploading anything
Merging PDFs is one of the most common document tasks, yet most online mergers ask you to hand your files to a remote server first. Pixohub does the opposite. Our Merge PDF tool runs entirely inside your web browser using the open-source pdf-lib library, so your documents are read directly from your device and stitched together locally. Nothing is transmitted to us, nothing is stored, and nothing is logged.
That matters because the files people merge are often sensitive: signed contracts, scanned passports and IDs, bank statements, medical records, or internal reports. When processing happens in the browser, those pages never touch the internet. You can even disconnect from Wi-Fi after the page loads and the merge will still work, which is the clearest proof that your data stays on your machine.
Full control over order and structure
Add two files or twenty, then drag them into the exact sequence you want before combining. Pixohub reads every page of every source PDF and writes them into one new file, preserving the original page dimensions, embedded fonts, images, and vector graphics. The result is a single, clean document rather than a zip of separate files.
There is no artificial page cap. The only practical limit is your device's available memory, so very large or image-heavy documents merge best on a computer rather than an older phone. The tool is completely free, requires no account, and never stamps a watermark on your output.
