How do I convert PNG screenshots to a PDF?
To convert PNG to PDF, drop your PNG screenshots or graphics into FixDoks's PNG to PDF tool, drag them into order, pick a page size and Original or Smaller file quality, then click Convert to PDF. Transparent areas become solid white on the page, and conversion happens in your browser, keeping PNGs lossless at Original quality.

Built for screenshots and graphics
PNG is the format most screenshots, diagrams and exported graphics are saved in, because unlike JPG it supports sharp edges, flat colours and transparency without introducing blur or colour banding around text. This tool is tuned for that kind of image: a stack of screenshots for a bug report, a set of diagrams for a manual, or exported charts for a document.
What happens to transparency
A PDF page does not support transparency the way a PNG can, so any transparent areas in your PNG become solid white in the final PDF page. This is usually exactly what you want, a logo or icon with a transparent background will simply sit on a white page like it would in a printed document. If you need to keep a design element floating over other content, that's a job for a design tool rather than a PDF conversion.
Original quality or smaller file
PNG is a lossless format, meaning no detail is thrown away when it's saved, which is exactly why it's the right choice for screenshots with small text and sharp UI edges, where a JPG would introduce blurry artefacts around every letter. Choosing Original keeps this losslessness in the PDF. Choosing Smaller file re-encodes the images and caps their size at 2000px, trading some of that sharpness for a lighter file, worth it if you're emailing a long batch of screenshots and don't need to zoom in closely.
Page size and layout
| Setting | Use when |
|---|---|
| Same as image | Screenshots of varying shapes that shouldn't be stretched or padded |
| A4 or Letter with auto orientation | A tidy, uniform document for printing or sharing |
| Small or large margin | Whether the image should fill the page or sit with white space around it |
Auto orientation looks at each image's shape and picks portrait or landscape accordingly, useful when your batch mixes tall app screenshots with wide desktop screenshots.
Typical uses
- Collecting a series of app or website screenshots into one PDF for a bug report or client review.
- Turning exported charts or diagrams into a single document to print or share.
- Combining a set of certificate or ID scans that were saved as PNG.
Common problems
- Transparent logo now has a white background. This is expected, since a PDF page cannot show transparency the way a PNG file can.
- File is larger than expected. PNG can be a bulky format for photos in particular; choose Smaller file quality, or mix in JPGs using image to PDF if your batch includes photos too.
- Need to add photos as well. Use image to PDF, which accepts PNG alongside JPG, WebP, GIF, BMP and HEIC in the same batch.
