Can I reorder the files?

Yes, drag the thumbnails to set the exact order before merging.

Is there a file or size limit?

No: since processing is local, you're only limited by your device's memory, not by a server quota.

Can I merge PDFs and images?

Yes. Drop JPGs or PNGs among your PDFs: each image becomes a page of the merged document.

Is PDF quality preserved?

Yes, the merge assembles pages as-is, with no recompression: text, images and fonts stay intact.

Are my files uploaded to a server?

No. All processing happens in your browser: your files never leave your device.

Drag the thumbnails to set the exact order.
Click “Merge”: the combined PDF downloads instantly.

Features

Drag-and-drop reordering

Each file appears as a thumbnail. Drag them to set the precise order before merging, with no limit on the number of documents.

Page preview

The first page of each file is shown as a thumbnail, so you can confirm at a glance that you're combining the right documents.

PDFs and images together

Add images (JPG, PNG) among your PDFs: they become pages of the final document, with no separate conversion step.

100% local processing

The merge runs in your browser. No upload to a server, no waiting to transfer: it's instant and private.

Use cases

Group several invoices or receipts into a single file to archive.
Assemble a report from sections written separately.
Bundle a résumé, cover letter and diplomas into one application file.
Combine scanned chapters into a single PDF book.

Your files never leave your device

Unlike most online PDF tools that upload your files to their servers, all processing happens right here, in your browser. No document is ever sent, stored or analyzed remotely: it's free, no sign-up, and private by design.
