About this image format converter
The image format converter changes an image between JPEG, PNG, and WebP. Each format has a job — JPEG for photos, PNG for graphics and transparency, WebP for strong modern compression — so converting is really about matching the file to where it will be used.
Reach for it when a platform demands a specific type, when a transparent graphic needs to stay PNG or WebP rather than become a flat JPEG, or when you want a smaller modern format for the web. Check the result, since converting a transparent image to JPEG fills the transparency with a solid background.
Common uses
- Convert an image to the format a website, store, or upload form requires.
- Turn a large PNG photo into a smaller JPEG or WebP file.
- Move images to WebP for smaller, web-friendly files.
Helpful tips
- Keep PNG or WebP when an image needs transparency; JPEG fills it with a solid color.
- Use JPEG for photographs and PNG for sharp graphics, logos, and screenshots.
- Confirm older platforms support WebP before sending that format.

Frequently asked questions
Which image format should I choose?
JPEG suits photos, PNG suits graphics and transparency, and WebP gives smaller files for the web. Pick the one the destination supports that matches the image type.
Why did transparency disappear after converting?
JPEG does not support transparency, so transparent areas become a solid background. Convert to PNG or WebP to keep transparency.
