PDF Contact Sheet Generator

• Choose a PDF document and enter Physical pages in the desired order, such as 3,1-2. Blank selects all when there are at most 30 pages.
• Set Grid columns and Cell size (pixels). The complete sheet must fit the geometry and output bounds.
• Select Create contact sheet and download pdf-contact-sheet.png. Saved annotations and forms are omitted.

Selecting 3,1,2 with two 128-pixel columns creates a 256×312 PNG with captions page-003.png, page-001.png and page-002.png.

• One PDF up to 50 MiB/500 source pages; at most 30 selected pages in listed order, fixed 72 DPI, 12 megapixels per rendered page and 100 megapixels total.
• Two to six columns and 64–1,024 pixels per cell. Final sheet up to 24 megapixels, 16,384 pixels per side and 20 MiB PNG.
• Rendered page PNGs must fit 20 MiB each and 100 MiB combined before composition. Unsupported render features fail without partial output.
• Saved annotations/forms are excluded. This is a visual overview, without searchable text, preserved PDF structure or clickable PDF navigation.
• The existing local PDF worker is bounded at 120 seconds; native rendering/encoding uses the current cancellation and disposal ownership. Color-critical fidelity is not guaranteed.
