Free online PDF merger

Merge PDFs online, locally.

Open Slay PDF in your browser, combine pages visually and download a merged PDF without sending the source documents to an app server.

Free to use

Merge PDFs from the browser with no subscription gate, no account flow and no watermark workflow.

Visual page order

Drag pages into the final order before exporting the combined document.

Local processing

Your documents and edits stay in this browser. Passwords are never saved.

Online convenience without the upload habit.

Most online PDF mergers ask for a file upload first. Slay PDF is still a web app, but the useful work happens on your device. Import the files, remove pages you do not need, reorder the rest and export the merged PDF.

This fits quick document bundles like scanned forms, receipts, contracts, statements and school paperwork where uploading originals is not worth it.
