PDF Merger & Splitter – Merge, Split, and Organize PDFs

I got tired of PDF tools that upload your documents to their servers, then hold them hostage until you pay. This one keeps everything on your device — merge contracts, split reports, extract pages, no upload, no account.

A note from me

I used this to merge 30+ scanned invoices into one PDF for a client. What surprised me: even 50-page PDFs merge in under 10 seconds in the browser. For scanned documents, keep the original page order — reordering scanned pages can break internal links if the PDF has bookmarks.

Frequently asked questions

Do my PDFs get uploaded anywhere?+

No. Everything runs in your browser. Your documents never leave your device.

Can I merge PDFs with different page sizes?+

Yes. Each page keeps its original size. The merged PDF just combines them in order.

Does merging add a watermark?+

No. The output is clean — no branding, no watermark, no extra pages.

Is there a page limit?+

No hard limit. I've merged 200+ pages without issues. Very large files depend on your device's memory.

Can I reorder pages before merging?+

Yes. Drag and drop the pages or files into the order you want. The final PDF follows that order.
