What happens to a PNG on the way into a PDF
Every PNG is re-encoded as a JPEG at the quality you set before it is placed on a page. That works well for screenshots and photos saved as PNG, but it means any transparent background turns solid white, since a JPEG and a PDF page cannot store transparency.
Page size for screenshots and diagrams
- Fit to image keeps the page the same shape as your screenshot, which avoids empty space around it.
- Letter or A4 with a small margin is a better choice when you plan to print the pages or add them to a report.
- Quality 90 or higher keeps small text in a screenshot readable; lower settings can blur fine lines and small type.
Good uses for PNG to PDF
- Turning a series of dated screenshots into one document to show a bug or a step-by-step process.
- Combining several exported diagrams or charts into a single file to send or print.
- Building a printable handout from PNG slides or graphics without opening a design app.
PNG to PDF FAQ
What happens to transparent areas?
The PDF page is white, so transparent parts of a PNG show as white in the final PDF.
Can I combine several PNGs into one PDF?
Yes. Each PNG becomes a page in the order you arrange them, or choose "One PDF per image" for separate files.
Is this good for screenshots?
Yes. Letter or A4 with a small margin keeps screenshots readable when printed.
Are my images uploaded?
No. The PDF is created in your browser and never leaves your device.
Will the file be much bigger or smaller than the PNG?
Usually smaller. Every image is re-encoded as JPEG at the quality you pick before it goes on a page, and JPEG is typically far more compact than PNG for photos and screenshots alike.
Can I keep the PNG's transparency in the PDF?
No. PDF pages have a solid background, so transparent PNG areas always come out white. If you need to keep transparency, keep the PNG file instead of converting it.
Why would I put a PNG in a PDF instead of just sharing the PNG?
A PDF opens the same way in any viewer, prints predictably, and can hold several screenshots or diagrams as numbered pages of one document instead of a folder of separate image files.
