What it does
A site asks for a JPG and you have a PNG, or an app won’t open a WebP. This tool makes a new copy of each image in the format you choose, at exactly the same width and height:
- To JPG: small files for photos, accepted almost everywhere. Transparent areas get a white or black background.
- To PNG: every pixel kept exactly, transparency included. Good for screenshots and logos.
- To WebP: small files for websites, with transparency kept.
It reads JPG, PNG, WebP, AVIF, GIF and BMP images. Each file’s card shows the change, such as PNG → JPG, the size in pixels and the file size before and after.
How to use it
- Drop your images on the box, paste them, or select Choose files. Select “Try a sample” to see two example images.
- Choose the format under Convert to. Every image is converted at once, and again when you change a setting.
- Select Download on a card to save one image, or Download all to save them together in a ZIP file.
- Press Ctrl+Enter (⌘+Enter on a Mac) to convert every image again, or Esc to stop the ones still working.
Good to know
- Each image can be up to 50 MB and 50 megapixels, and you can add up to 20 images at once.
- The tool reads still images only. Animated GIF, WebP and PNG images and HEIC photos aren’t supported yet.
- Quality applies to JPG and WebP; Background applies to JPG only.
- Files keep their name with the new extension, such as
logo.jpgfromlogo.png. An image saved in its own format gets-convertedadded, such asphoto-converted.jpg. - Saving as WebP needs Chrome, Edge or Firefox. Safari opens WebP images but can’t save them, so choose JPG or PNG there.
Privacy
Your images are processed on your device: the tool runs in your browser and doesn’t upload them. The new image is made from the pixels alone, so camera details and location data from the original are always removed.
