Split an A4 PDF into a quarter-page A6 PDF

Choose a PDF containing up to 10 qualifying A4 pages. Each source page becomes four A6 pages — up to 40 A6 pages in one combined output PDF — in top-left, top-right, bottom-left, bottom-right order. If any single page does not qualify (wrong size, rotated, over the page limit, or otherwise non-conforming), the whole document is rejected and nothing is produced. Processing stays in this browser tab.

The output PDF is rebuilt from decoded drawing commands and an allowlisted set of visual resources. It does not preserve source actions, attachments, annotations, metadata, form fields, or orphan objects. Visible, supported visual content can remain sensitive. This tool is not a validated redaction or sanitization product and does not promise removal of arbitrary confidential content. Do not use this tool to make a document safe to disclose.
