PDF

Merge, split, shrink and export documents locally.

Your files stay on your device. The tool works directly in your browser, using your device to process your files. Nothing is sent to our servers, and we never receive, store, or see your files or figures.

Documents that stay confidential

PDFs are where the privacy question stops being abstract. Contracts, medical records, bank statements, signed agreements and identity documents all arrive as PDFs, and the popular online tools all upload them.

These tools open and rebuild documents inside your browser instead. Nothing is transmitted, so there is no retention window to trust and no queue to wait in.

The tools

  • Merge PDF: combine documents in any order, with page counts shown so you can confirm you have the right files.
  • Split PDF: extract page ranges, split into single pages, or break into fixed-size chunks.
  • Compress PDF: two honest modes, one lossless and one that rasterises, with the trade-off stated before you run it.
  • Bulk PDF compress: the same two modes over a whole queue of documents, with one setting for the batch and the results as a ZIP.
  • PDF to JPG: render pages to images at up to 300 dpi.
  • Word to PDF: convert a .docx with its headings, lists, tables and pictures intact, without the document going anywhere.

What merging and splitting preserve

Page content, embedded fonts, images and vector graphics are copied exactly. Nothing is re-rendered, so quality is untouched and text stays selectable. Document-level structures (bookmarks, form field definitions, digital signatures) do not survive, because they belong to the source document rather than to individual pages. In particular, merging invalidates a digital signature, because a signature certifies one specific byte sequence.

On file size limits

There is no limit imposed by us, because there is no upload. The real constraint is your device’s memory: a few hundred megabytes is generally fine on a desktop, considerably less on a phone. If a very large document fails, process it in parts.
