PNG and WebP
The conversion runs in your browser, your images are not uploaded.
Convert PNG images to JPG, one by one or many at once. Set the quality, pick a background colour for transparent areas, download singly or as a ZIP. Free, no sign-up and no upload.
Drag your PNG files into the field or click “Choose images”. Several images at once are possible, WebP works too.
Set the JPG quality, the default is 92. For transparent areas pick the background colour, white is the default. Every change converts the images again.
Download each image on its own or all together via “All as ZIP”.
Photos are usually many times smaller as JPG than as PNG. That helps when sending by email, uploading to portals with a size limit and on web pages that should load fast. Many forms, shops and print services only accept JPG anyway.
Screenshots, logos, diagrams and graphics with text consist of sharp edges and few colours. JPG handles that badly: the file barely gets smaller and edges pick up a slight haze. If you need transparency, PNG is the only option anyway.
A cut-out logo or product image has transparent areas. In a JPG they have to be given a colour. Use the colour of the surface the image will sit on, then the transition goes unnoticed. White suits documents and most web pages.
Need a PNG from a photo? There is JPG to PNG for that. You can send several images as one document with PNG to PDF, and make large photos smaller with Compress image.
JPG has no transparency. Transparent areas are therefore filled with the background colour you pick, white by default. Semi-transparent edges, for example on logos, are blended with that colour. That way you get no black areas and no dark fringes.
The default is 92. With photos you usually cannot tell it from the original, and the file is still clearly smaller than at 100. For print or archive you can go higher, for email and web pages less is often enough. The lower the value, the smaller the file and the sooner you see traces on edges and text.
With photos almost always, often by a large factor. With screenshots, graphics with few colours or a lot of text, the JPG may barely shrink or even grow and look softer at the edges. Keep such images as PNG. After the conversion the list shows both file sizes.
Yes. Drag any number of files into the field or select them together. You can download each image on its own or all together as a ZIP archive. With very many large images an older phone mostly just needs some time.
Yes, as long as your browser can read WebP. All current versions of Chrome, Edge, Firefox and Safari can. Transparent WebP images get the chosen background colour, just like PNGs.
No. The conversion runs entirely in your browser, the images never leave your device. Metadata such as capture date, camera or location is not carried over into the JPG file.
