Image Converter

Convert images between JPG, PNG and WebP. One image or a whole batch.

How this was calculated
Your images never leave your device. They are converted in your browser.
About the Image Converter
Image Converter changes images between JPG, PNG and WebP, one at a time or in a batch, and shows how much smaller or larger the new files are.
Pick WebP for the smallest files on the web, JPG for photos that need to open everywhere, and PNG for graphics that need transparency or perfect sharpness.
How to use it
  1. Choose your images.
  2. Pick a format and quality.
  3. Download the converted files, or all of them as a zip.
Example
A 2 KB PNG logo saved as WebP came out at under 1 KB, with the same size and look.
Questions
What happens to transparency?
WebP and PNG keep it. JPG can't, so transparent areas become white.
Does quality affect PNG?
No. PNG is lossless; quality applies to JPG and WebP.
Can it open HEIC photos from iPhones?
Only if your browser can. Safari can, most others can't yet.
