When you turn an image into a PDF, the source format affects how the result looks and how big the file is. So should you convert PNG to PDF or JPG to PDF? The short answer: use PNG for sharp graphics and text, and JPG for photos. Here is the full picture — and the good news is our converter handles all of them.

JPG (also written JPEG) uses lossy compression. It throws away some detail to make files small, which is perfect for photographs with lots of colours and gradients. PNG uses lossless compression — it keeps every pixel exact and supports transparency, which makes it ideal for screenshots, logos, diagrams and anything with crisp edges or text.
And to clear up a common question: JPG and JPEG are identical. The name is just shortened on some systems. If you are choosing between them, read how to convert JPG to PDF — the steps are the same.

When to convert PNG to PDF
- Screenshots of apps, chats or web pages — text stays sharp and readable.
- Logos and graphics with solid colours and hard edges.
- Diagrams, charts and line art where blurring would lose detail.
- Anything with text that must stay perfectly legible.
When to convert JPG to PDF
- Photographs from a phone or camera — smaller files with no visible quality loss.
- Scanned documents shot as photos, where file size matters for emailing.
- Image-heavy sets like a batch of receipts or property photos.
Does the format change how I convert?
Not at all. Whether your images are PNG, JPG or JPEG, the process is the same: drop them into the converter, arrange the pages, and download. You can even mix formats in one PDF — a PNG screenshot followed by a JPG photo, each as its own page. To merge several, see combining multiple images into one PDF.
The bottom line
Pick PNG when sharpness and text clarity matter most, and JPG when you want smaller files for photos. Either way, our converter keeps your images at full resolution and the choice is genuinely yours — there is no wrong answer for most everyday documents.
