About the Image Converter
Convert pictures to the format you need: JPG for compatibility, PNG for transparency and sharp graphics, or WebP for the smallest files on the web. Convert many images at once and download them together.
How to use it
- Add your images (JPG, PNG, WebP, GIF, BMP and others your browser can open).
- Choose the output format and quality.
- Download the converted files.
Which format should you choose?
JPG is the most compatible format for photos and opens everywhere. PNG is lossless and supports transparency, so it suits logos, icons, screenshots and anything with sharp text. WebP produces the smallest files for both photos and graphics and is supported by every modern browser, which makes it the best choice for websites.
What happens during conversion
The image is redrawn and saved in the new format at the quality you set. Converting to JPG fills transparent areas with white, because JPG has no transparency. Converting a JPG to PNG won't restore detail already lost to compression, but it does stop further loss when you edit and save again.
Batch conversion
Drop in a whole folder of images, pick the output format once, and download them all as a ZIP. GIF, BMP and other formats your browser can open are converted too; animated GIFs are saved as a single still frame.
Frequently asked questions
What happens to transparency when converting to JPG?
JPG does not support transparency, so transparent areas are filled with white.
Which format is best for websites?
WebP usually gives the smallest files at the same visual quality and is supported by all modern browsers.
Can I convert HEIC iPhone photos?
Only if your browser can open HEIC files (Safari can). Otherwise, set your iPhone camera to ‘Most Compatible’ to save JPGs.
