How to Use: Three Easy Steps

Step 1

Choose "Merge PDF" or "Split PDF", then drag & drop or click to upload your PDF files.

Step 2

Use ↑ / ↓ to reorder files when merging; choose one file per page or enter page ranges when splitting.

Step 3

Click "Merge & Download" or "Start Split" and the result PDFs are saved to your device instantly.

Your files never leave your device. Everything is processed locally — 100% private.

No upload or download time — most merges and splits finish in seconds.

100% free to use — no watermarks, no hidden fees, no usage limits.

How large can my PDF files be?

There is no hard limit, but performance depends on your device's memory. Very large files (100MB+) may be slow; we recommend files under 50MB.

How is the order of the merged file determined?

Pages are merged in the order of the file list. Use the ↑ / ↓ buttons to reorder files after uploading, or remove files you don't need.

Can I split by custom page ranges?

Yes. Choose "Custom page ranges" and enter something like 1-3, 5, 8-10 — each range becomes its own PDF file.

How do I download the split results?

Every generated file has its own download button; when there are multiple files you can also download everything as a single ZIP archive.

Are my files uploaded to a server?

Absolutely not. All processing happens entirely inside your browser — files are never sent over the internet or stored anywhere.
