How it works

Three simple steps — everything happens in your browser.

Drag and drop or click to select multiple PDF files from your device. No file limit.

Drag files to reorder them. The order in the list is the order they appear in the final merged PDF.

Click merge and download your combined PDF instantly. All pages preserved in original quality.

Your PDF files never leave your device. All merging is done locally using PDF-lib inside your browser. No data is sent to any server — ever.

No upload or download delays. Merging happens instantly on your device. Even large PDFs combine in seconds.

Pages are copied at the binary level — no re-rendering, no quality loss. Fonts, images, vectors, and links are all preserved perfectly.

Simply drag files to rearrange the order. The page count for each file is shown so you know exactly what you're merging.

• You can add PDFs in batches — click "Add More" to append additional files after the initial selection.
• Drag to reorder files before merging — the list order equals the page order in the final PDF.
• Merging preserves all bookmarks, links, and form fields from the original PDFs.
• For very large merges, ensure your browser has enough memory — Chrome handles this best.
