Your images are processed instantly on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and no copies kept anywhere.
Frequently asked questions
- Are my files uploaded to a server?
- No. Everything happens entirely on your own device, inside your browser. Your PDFs and any passwords never leave your computer, so there are no upload waits and no copies kept anywhere.
- How many PDFs can I merge at once?
- As many as you like — there are no file-count or size limits from us. Because the merging runs locally, the practical limit is your device’s memory.
- Can I reorder the files before merging?
- Yes. Each file is numbered and you can move it up or down, so the final PDF follows the exact order you set.
- Will merging change the quality of my PDFs?
- No. Pages are copied across exactly as they are — text, images and formatting are preserved at full quality.
