After you choose a PDF, RasterMint shows the page count and lets you choose a DPI setting. When conversion starts, each page is rendered and added to the preview grid.

For long documents, 150 DPI is usually the best first pass. Use 300 DPI only when the full document needs print-quality output.

Multi-page PDF to PNG export is useful when a portal, gallery, review workflow, or archive expects individual image files instead of a PDF.

• Convert reports into image previews.
• Export slides or handouts as PNG files.
• Create page images for document review.
• Package all converted pages into one ZIP.

Instead of clicking download on each page, the ZIP export packages every converted PNG into a single archive. This is useful when you need to upload all pages to a system that accepts image files but not PDFs.

The ZIP file is generated in your browser using JavaScript. It is not sent to or stored on any server. Each PNG inside the ZIP is named with its page number for easy identification.

RasterMint shows a thumbnail preview of each converted page. This lets you verify the output quality before committing to a download. If a page looks blurry or cut off, you can adjust the DPI setting and re-convert.

This preview step is especially useful for documents with mixed content types, such as reports that combine text, charts, and photographs on different pages.
