Private by architecture

Your PDF never leaves your device

Dismerge PDF reads and rebuilds your document inside your browser. There is no upload endpoint, temporary cloud folder, or file-retention timer, because we never receive the file.

  1. You choose a PDF. Your browser opens the local file.
  2. The browser does the work. Page copying happens on your device.
  3. You download the result. New files go straight back to you.

Common questions

Good to know

Short answers to what people ask before they choose a file.

Is Dismerge PDF really free?

Yes. The tools have no account requirement, watermark, or artificial daily task limit. Browser memory and the documented file limits still apply.

Does “online” mean my PDF is uploaded?

No. Online means the tool is available through this website. The PDF bytes are processed locally in your browser and are not sent to Dismerge PDF.

Will splitting lower the quality?

No recompression is intentionally applied. Pages are copied into new PDF files while retaining their dimensions and rotation.

Can I split a password-protected PDF?

Not yet. Unlock the document using a trusted local application before using the splitter.
