Images → PDF
Combines multiple images into a single PDF. JPEGs are embedded without re-encoding.
Combines any number of images (JPEG, PNG, WebP, AVIF) into a single multi-page PDF — one image per page. Page order is changed with the up/down buttons in the file list; unwanted files are removed via the × button. Page size can be A4, Letter, Legal or “match image size” (1 px → 1 PDF point, handy for screenshots and scans). Orientation is auto (follows the image aspect), portrait or landscape. Margin is none, 10, 20 or 30 mm. Each image is fitted into the usable area with aspect ratio preserved (contain). JPEG files are embedded into the PDF without re-encoding via the /DCTDecode filter — the bytes are identical to the source, no second-generation quality loss. PNG/WebP/AVIF files are re-encoded into JPEG at the chosen quality (92% by default) — transparency is filled with white (JPEG has no alpha channel). The PDF is built by hand: Catalog, Pages tree, pages with Image XObject and Contents stream, xref and trailer — no third-party PDF libraries. Files never leave your device.
