Merge PDF Offline on Mac — 100% Private
Combine PDF files on Mac without uploading to iCloud, Dropbox, or any server.
macOS has a built-in PDF merge feature in Preview, but it's clunky for more than 2 files and doesn't give you drag-to-reorder before merging. FixIt Localy runs a full PDF merger inside Safari or Chrome on your Mac — no uploads, no iCloud sync, no app install. Drag files in, reorder them visually, merge, and download. The entire process uses your Mac's local memory through WebAssembly.
How It Works
Open the PDF Merger in Safari or Chrome
Click the button below. The tool opens instantly in your current browser — no app installation or Apple ID required.
Add your PDF files
Drag multiple PDFs onto the tool or click to browse. Drag the thumbnails to reorder the files before merging.
Merge and download
Click Merge PDF. Your combined file downloads to your Mac's Downloads folder in seconds. Nothing is stored anywhere.
Why No File Upload?
Zero Data Exposure
Your files are processed using WebAssembly inside your browser tab. They are never transmitted to any server.
Instant Deletion
When you close the browser tab, all processed data is immediately destroyed. Nothing is cached or logged.
PDPL & GDPR Safe
No third-party data processor is involved. Fully compliant with Saudi Arabia's PDPL and the EU's GDPR by design.
Frequently Asked Questions
Does this work in Safari on Mac?
Yes. Safari on macOS fully supports WebAssembly, which powers the local PDF merging. Chrome and Firefox on Mac also work perfectly.
Is this better than using Preview on Mac to merge PDFs?
For multi-file merging, yes. Preview requires you to open each file separately and drag thumbnails between windows — it becomes unwieldy with 5+ files. This tool handles any number of files in a single drag-and-drop interface with visual reordering.
Will the merged PDF have a watermark?
No. There is no watermark, no branding, and no modification to your PDF content beyond combining the pages. The output is a clean merged PDF.
Can I merge password-protected PDFs on Mac?
You would need to unlock them first using a PDF unlock tool. Once unlocked, they can be merged normally.
How many PDFs can I merge at once?
There is no limit on the number of files. The only constraint is your Mac's available RAM. Merging 20-30 standard PDFs works smoothly on any modern Mac.
