How to Merge PDF Files
- Upload PDFs — Drag two or more PDF files onto the drop zone, or click to browse. You can add files multiple times to arrange them in the right order.
- Reorder pages — Drag file cards up or down to set the merge order. Use the ✕ button to remove a file.
- Merge & download — Click Merge. A new PDF combining all pages in your chosen order will be ready in seconds.
Why Use a Browser-Based PDF Merger?
Online PDF tools that ask you to upload files pose a privacy risk — your documents could be stored or analyzed on someone else's server. GameImage.tools merges PDFs entirely in your browser using pdf-lib. Your files never leave your device.
Frequently Asked Questions
Can I merge PDFs with different page sizes?
Yes — each page keeps its original size in the merged document.
Why does some PDF show an error when uploading?
Some PDFs use newer internal structures or have permission protection that browser tools cannot parse. Open the PDF in your reader, save a fresh copy, then upload again.
Is there a file size limit?
Each PDF can be up to 50MB, and you can merge up to 10 files at a time. All processing happens locally so there's no network bottleneck.
