What does an image converter do?
It saves the same picture in a different file type. The pixels you see stay the same. What changes is how the file is packed: how big it is, whether it can have a see-through background, and which apps will open it.
Most images online are one of three types. JPG is the old reliable one for photos. PNG keeps every pixel exactly and can be see-through. WebP is newer and makes smaller files than both.
This converter works in your browser. You choose an image, pick a format, and the new file is made on your device. You see its size before you download it.
How to convert an image
- Add your image. Click the box, drag a file in, or paste a screenshot with Ctrl+V or Cmd+V.
- Pick a format. PNG, JPG or WebP. The preview shows the converted file.
- Set the quality. For JPG and WebP, lower quality makes a smaller file. Watch the size change as you move the slider.
- Download it. The file keeps its name, with the new extension.
Which format should I pick?
| Format | File size | See-through | Best for |
|---|---|---|---|
| PNG | Largest | Yes | Logos, screenshots, cut-outs |
| JPG | Small | No | Photos, email, printing |
| WebP | Smallest | Yes | Websites, online shops |
Photos go to JPG. A camera photo has millions of colours and soft edges. JPG squeezes those well, and every phone, computer and email app opens it.
Logos, text and cut-outs go to PNG. PNG keeps sharp edges and flat colours clean, and it keeps a see-through background.
Websites go to WebP. It is usually a quarter to a third smaller than JPG at the same look, so pages load faster. Every current browser shows it.
What happens to a see-through background?
PNG and WebP can store see-through pixels. JPG cannot. When you convert a transparent image to JPG, those areas are filled with white. The converter tells you when this will happen.

JPG
If you made a cut-out with the background remover, keep it as PNG or WebP so it stays see-through when you place it on a slide or a product page.
Tips for smaller files
- Start at 90% quality. Most people cannot tell it from 100%, and the file is much smaller.
- Do not convert JPG to PNG to improve it. The detail JPG dropped does not come back. The PNG is just bigger.
- Resize before you share. A 4000 px photo is far more than a phone screen needs. The image resizer fixes that first.
- Keep the original. Converting creates a new file. Your original stays untouched on your device.
