PNG
PNG (Portable Network Graphics) is a lossless raster image format. It supports transparency (alpha channel) and 48-bit color depth. PNG files are commonly used for screenshots, diagrams, charts, and graphics with text. PNG does not support multi-page documents.
PDF (Portable Document Format) is the ISO 32000 standard for electronic documents. PDF encapsulates images, text, and vector graphics in a fixed-layout container. PDFs support multiple pages, bookmarks, and consistent printing. Every operating system includes a PDF viewer.
Warum Konvertieren
Convert PNG images to PDF for official document submission. Combine multiple PNG screenshots into a single multi-page PDF report. Preserve transparency-free versions of graphics for printing. Package diagram collections into one distributable file. Meet upload requirements on portals that only accept PDF format.
Häufig Gestellte Fragen (FAQ)
Can I combine multiple PNG files into one PDF?
Yes. Select multiple PNG images and they merge into a single multi-page PDF. Each PNG occupies one page. The order matches your selection sequence.
Does PNG to PDF conversion preserve transparency?
PDF rendering fills transparent areas with white by default. The option to preserve transparency depends on the PDF viewer. For guaranteed results, transparent areas render as white in the output PDF.
What page size does the output PDF use?
By default, the page dimensions match the PNG image dimensions. Standard page sizes (A4, Letter, Legal) are available as options. Images are centered and scaled to fit the selected page size.
Is the image quality preserved in the PDF?
Yes. PNG pixel data embeds into the PDF without re-compression. The output contains lossless image quality identical to the original PNG source file.
What is the maximum PNG file size supported?
No strict limit. Browser memory is the constraint. PNG files up to 100 MB convert successfully on most modern devices. Multiple files process in batch mode.
