Are my PDF files uploaded to a server?

No. The entire merge happens inside your browser using WebAssembly. Your files never leave your device, which makes this safe for confidential or financial documents.

Is there a limit on how many PDFs I can merge?

There is no hard limit on the number of files. Very large merges are only bounded by your device's available memory, since all the work is done locally.

Will merging reduce the quality of my PDFs?

No. Merging copies pages exactly as they are - text stays selectable and images keep their original resolution. Nothing is re-compressed.

Can I change the order of the files?

Yes. Drag the files up or down in the list before merging to set the exact order the pages will appear in the final PDF.

Do I need to install anything or create an account?

No. The tool runs entirely in your browser with no sign-up, no software, and no watermark.

About Merge PDF

Merging PDFs is the everyday task of stitching several documents into a single file - combining a cover letter with a resume, bundling invoices for the month, or assembling scanned pages that arrived one at a time. Our Merge PDF tool does it instantly and keeps the page order entirely under your control.

Unlike most online mergers, nothing you add here is ever uploaded. The moment you drop your files in, they are read and combined by your own browser using WebAssembly - so a confidential contract or a bank statement never leaves your device. When the merge finishes you get one clean PDF back, ready to download.

Combine two documents or two hundred; there is no per-file limit and no watermark.

Full control of order

Your files never leave your device

Most online PDF tools upload your document to a server to process it. This one does not. Every operation runs inside your own browser using WebAssembly, so your files are read, processed, and saved locally - they are never transmitted, stored, or seen by Sapphire Broking or anyone else. That makes it safe to use with financial statements, contracts, and identity documents.
