How to Convert PNG to JPG
- Add one or more PNG files to the converter above.

- Click Convert, preview the result and download each JPG or everything as a ZIP.
Why Does My PNG Turn Black When Converted to JPG?
JPG doesn't support transparency. When a transparent PNG is converted, every see-through pixel has to become a solid color, and many converters and apps fill it with black. K4Converter fills transparent areas with white by default, and you can choose any other color with the Background option. The thumbnails update instantly, so you can see the result before converting.
PNG vs JPG: Which Should You Use?

|---|---|---|
| Compression | Lossless | Lossy (adjustable) |
| Transparency | Yes | No |
| Typical file size | Large | 3–10× smaller |
| Best for | Logos, screenshots, text | Photos, email, social media |
Choosing the Right JPG Quality
- 90–100%: near-identical to the original. Use this for printing or important photos.
- 75–85%: the sweet spot for websites and email, with much smaller files.
- Below 70%: very small files, but you may notice blurry edges on text.
Tip: Screenshots with lots of text look sharper as PNG or WebP. Convert to JPG mainly for photos and large images.
