Why convert PNG to PDF?
PDF makes PNG images easier to print, submit as documents, email as one attachment, or share in a fixed page order.
Use pages that match each image or choose A4 or Letter with your preferred orientation and margins. Transparency is retained, and several PNGs can become one ordered PDF or separate documents.
Frequently Asked Questions
Can I combine multiple PNG images into one PDF?
Yes. Add the PNG images in the order you want them to appear and choose One PDF. Each image becomes one page. Choose Separate PDFs when you want individual documents in a ZIP.
What happens to transparent PNG backgrounds?
Transparent and semi-transparent pixels are retained in the PDF image layer. Their appearance can depend on the background used by the PDF viewer or the page behind the image.
Which PDF page size should I choose?
Choose Fit image for pages that follow each PNG's dimensions. Choose A4 or Letter for printing and document systems that expect a standard paper size.
Can I choose portrait or landscape pages?
Yes. A4 and Letter pages can use automatic, portrait, or landscape orientation. Automatic follows the shape of each PNG.
Can I add margins around each PNG?
Yes. Choose no margin, a small margin, or a large margin. Each image is centred and fitted to the page without changing its proportions.
What does Enlarge smaller images do?
On A4 or Letter pages, this lets a smaller PNG fill more of the available page. Leave it off to avoid enlarging an image beyond its original pixel dimensions.
Does converting PNG to PDF reduce image quality?
PNG images are embedded in the PDF without JPG compression. Their pixels and transparency are retained, while the selected page layout controls their printed size and position.
Does the PDF keep PNG metadata?
The PDF keeps the visible image and transparency but does not copy PNG text, EXIF, colour-profile metadata, or comments. Keep the original PNG when you need that information.
Are my PNG images uploaded?
No. PNG to PDF conversion runs locally in your browser. Your images are not uploaded to Crest Convert or stored on our servers.
How can I turn PDF pages back into PNG images?
Use the PDF to PNG converter to turn every page, or only selected pages, into individual PNG images.
