Merge PDF - PDF Stacker: Combine PDFs & Convert Images to PDF Instantly
Tired of juggling multiple PDF files and separate image-to-PDF converters? PDF Stacker does both in one place. Merge any number of PDF documents into a single file, and convert your JPG or PNG images into PDF pages — all directly inside your browser, with no account, no desktop software, and no file ever leaving your computer.
KEY FEATURES
• Merge unlimited PDF files into one combined document
• Convert JPG and PNG images into PDF pages — drop a single image to use it as a quick Image to PDF converter, or mix images with PDFs in any order
• Choose "Fit to A4" per image, or keep its original size, before merging
• Drag-and-drop to reorder files exactly the way you want before merging
• Optional blank separator page between merged documents
• Customize the default filename for your merged PDF
• See live page counts and file sizes before you merge
• Works entirely offline — 100% local processing, zero uploads
IMAGE TO PDF, BUILT IN
Need to turn a photo, scan, or screenshot into a PDF? Just drop a single JPG or PNG into PDF Stacker — it instantly works as a free Image to PDF converter, no separate tool required. Add more images or PDFs afterward to combine everything into one document.
WHY PDF STACKER
Most online PDF mergers and image-to-PDF converters require you to upload your files to a third-party server, which is slow and raises privacy concerns. PDF Stacker processes everything locally in your browser using modern, secure web technology — your documents and images are never sent anywhere.
HOW IT WORKS
1. Click the PDF Stacker icon and open the merge tool (or drop files directly onto it).
2. Add your PDFs and/or images, then drag to reorder them into the sequence you need.
3. Click "Merge & Download" to instantly get your combined PDF.
PRIVACY FIRST
No accounts. No tracking. No watermarks. No file uploads. Your settings (like your preferred output filename) are stored only in your browser via Firefox's sync storage.
Perfect for students, professionals, and anyone who regularly needs to combine reports, contracts, scanned pages, photos, or invoices into one tidy PDF.
