What you should know
PNG to PDF puts an image into a document ready to send or print: a screenshot, a scanned receipt, a floor plan. Many online forms accept only PDF, even for a simple image.
The PNG is embedded as is, without recompression: the PDF contains exactly the file's pixels. The image is centred on an A4 page, portrait or landscape depending on its shape, with a margin of about 8 mm.
Strengths
- No recompression: the PDF's image is the PNG itself
- A4 page oriented automatically to match the image
- A small image is never stretched to the point of blurring
- The file stays on your device throughout the conversion
Limitations to know
- One image makes one page: several PNGs produce several PDFs
- Text visible in the image is not selectable
- A photographic PNG produces a heavy PDF
- The page size is fixed to A4
When to use it
Convert to attach a screenshot or a scanned document to an administrative file, a form or an email that demands a PDF. To gather several pages into one file, convert each image and then combine them with the PDF editor.
Quality, size and compatibility
Quality is exactly that of the PNG, since the image is not re-encoded. The PDF therefore weighs about as much as the image: for a heavy photo, converting it to JPG first makes the document much lighter.
Frequently asked questions
- Does the image lose quality in the PDF?
- No. The PNG is embedded in the PDF as is, with no recompression: zooming into the document shows exactly the original pixels.
- How do I put several images into a single PDF?
- Convert each image to PDF, then merge the resulting files in FileXvert's PDF editor, where you can also reorder the pages.
