About Merge PDF
Combine multiple PDF files into one document easily. Drag and drop your PDFs, reorder them, and merge into a single file. All processing happens in your browser — your files are never uploaded to any server.
Frequently Asked Questions
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most devices can handle PDFs up to 100MB combined.
Are my files secure?
Absolutely. Your PDF files never leave your device. All merging is done locally in your browser using JavaScript.
