100% Free & Secure PDF Merger Tool

Yes. PDFGami is completely free with no paid tier, no usage cap per day or per month, no file size limit, and no watermark on the output. Because the merge runs in your browser instead of on our servers, there are no bandwidth or compute costs to pass on.

No. No registration, no email, no Google/Apple OAuth. Drop your PDFs, click Merge, download the combined file. That is the entire flow.

PDFGami is exactly that. Many "free" PDF mergers either require an email to download the result, cap the file size at a few MB, or stamp a watermark on the output. PDFGami does none of those.

There is no per-day or per-month cap. You can merge two PDFs or fifty in one session. The only real limit is your device memory because everything runs in your browser.

No artificial limit. Server-based "free" mergers usually cap at 25–50 MB. Since PDFGami parses the file in your browser, the only constraint is what your device can hold in memory — typically gigabytes.

It depends on the tool. Cloud-based free mergers upload your file to their servers and often store it for hours afterward — read the privacy policy. PDFGami runs entirely in your browser, so the file is never uploaded. That makes it safe for contracts, NDAs, medical records, and other confidential PDFs.
