Image Format Converter
100% PrivateImage ToolsConvert an image between PNG, JPG and WebP, the three formats the web runs on.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Choose the image you want to convert; its current format and size are shown.
- 2Pick the target format. For JPEG and WebP you also get a quality slider.
- 3For JPEG, pick the background color that will sit behind any transparent areas.
- 4Convert, compare the before and after sizes, and download.
A logo saved as PNG with a transparent background converts to JPEG by placing the artwork over the background color you pick, white by default. The same file converted to WebP keeps its transparency and usually ends up smaller than both the PNG and the JPEG.
- JPEG cannot store transparency: transparent pixels become the background color you choose. PNG and WebP keep the alpha channel.
- Converting a JPEG to PNG does not restore quality lost in the original JPEG compression; it only changes the container.
- Animated GIFs convert using their first frame only, and the output is a still image.
PNG for graphics, screenshots and anything needing transparency or pixel-perfect edges. JPEG for photos when a site does not accept WebP. WebP for photos and graphics on the modern web, where it is typically smallest.
About this tool
The Image Format Converter re-saves an image as PNG, JPEG or WebP, the three formats the web runs on. Use it when a form only accepts JPG, when a transparent PNG needs to become a photo-friendly JPEG, or when WebP's smaller files would speed up your page.
