Features
The Image to PDF tool supports converting JPG, PNG, WebP, BMP and other common image formats to PDF documents. Select multiple images at once, reorder via drag-and-drop, then generate a multi-page PDF. Each image occupies one page, automatically fitted to A4 paper size (custom page dimensions also supported). Image quality is fully preserved without additional compression (unless you enable the compression option). The entire process runs locally in your browser — your photos never upload to any server. Common use cases: combining scanned receipts into one PDF for archiving, converting ID photos to PDF for online applications, assembling design screenshots into presentation documents.
