When to convert PNG images to PDF
Use PNG to PDF when screenshots, transparent graphics, scans, or exported PNG pages need to become a single PDF. Each PNG becomes one PDF page, which is convenient for sharing a grouped document instead of many separate image files.
Layout and result quality
The browser places each PNG on a portrait PDF page and scales it only if it is larger than the printable area. Review the result after download, especially when the source image contains small text or detailed UI screenshots.
Privacy and limits
PNG to PDF runs locally in your browser and does not upload images to 100PDF. It does not provide OCR, image editing, or background removal. Very large PNG files can require more browser memory, so keep source images until you confirm the PDF result.
