Popular conversions
JPG vs. PNG vs. WebP
- JPG (JPEG): made for photos. Lossy compression keeps files small; no transparency.
- PNG: lossless and supports transparency. Great for screenshots, logos and graphics; photos as PNG are often large.
- WebP: a modern format with efficient compression and transparency support. Widely supported by current browsers, less so by some older software.
None of them is best for everything; it depends on the image and where you will use it.
What happens to image quality?
Converting to JPG or WebP uses lossy compression with a quality setting: higher quality keeps more detail and usually creates a larger file. Converting to PNG adds no further loss. No conversion can restore detail that an earlier lossy save already removed.
What happens to transparency?
PNG and WebP keep transparent areas. JPG cannot store transparency, so when you convert a transparent image to JPG you choose a background colour, white by default. Converting a JPG to PNG or WebP does not create transparency.

Frequently asked questions
How do I convert an image?
Choose a JPG, PNG or WebP image above, select the output format, then click Convert Image and download the result. The file keeps its name with the new extension.
Can I convert JPG to PNG?
Yes. Choose PNG as the output format. The PNG is a lossless copy of the image as it is now; it does not restore detail the JPG compression removed.
Can I convert PNG to JPG?
Yes. Choose JPG, set the quality and, for transparent images, the background colour. The JPG is usually much smaller than the PNG.
Does converting an image reduce quality?
Converting to JPG or WebP compresses the image, so some detail can be lost; the quality setting controls how much. Converting to PNG adds no loss.
What happens to transparent areas when converting to JPG?
JPG has no transparency, so transparent areas are filled with the background colour you choose: white, black or a custom colour.
Which image format should I use?
It depends on the image and where it goes. JPG suits photos and is widely accepted. PNG suits screenshots, logos and anything that needs exact pixels or transparency. WebP is compact and supports transparency, but some older software cannot open it.
Are my images uploaded?
No. The conversion runs in your browser and your image never leaves your device.
Does converting keep the photo metadata?
Not in the new image: your browser saves it without camera details, the date taken or GPS location. Photos are turned upright first, so they still display correctly. To see what a photo contains, use View Image Metadata before converting. If the tool offers your original unchanged, its metadata stays as it was.
