What PDF to ZIP does
PDF to ZIP is a page-image exporter: it renders every page against a white background, encodes each canvas as PNG, and collects the numbered files in one ZIP. It does not simply place the original PDF inside an archive.
The selected DPI ranges from 72 for smaller, faster exports to 300 for sharper, larger images. Every output is a ZIP, even when the source contains only one page, which keeps the download behavior consistent.
How to use PDF to ZIP
- Choose one verified PDF no larger than 25 MB.
- Set a render resolution from 72 to 300 DPI.
- Render the pages, download the ZIP, and inspect the numbered PNG files.
Important details
The ZIP contains page images
Each page becomes an independent PNG named with a padded page number. Selectable text, links, forms, and vector objects are flattened into pixels in those images.
DPI changes memory, clarity, and size
Higher DPI creates more pixels and can improve small-text readability, but it increases browser memory use, processing time, and ZIP size. Canvas safety limits still apply to unusually large pages.
Practical uses
- Extract slide or document pages for use as preview thumbnails.
- Create page images for a system that accepts PNG files but not PDF.
- Archive numbered raster representations of a short visual document.
Privacy and limitations
PDF parsing, page rendering, PNG encoding, and ZIP assembly occur locally in your browser. PagesTools does not upload the document.
The input limit is 25 MB and 100 pages, with DPI from 72 to 300 and canvas bounds of 12,000 pixels per side or 40 megapixels per page. Encrypted, malformed, or active-feature PDFs are rejected, and raster output is not editable PDF content.
