About this tool
The right format for the right job
JPG, PNG, and WebP each behave differently
JPG produces small files for photos with many colors but does not support transparency. PNG is larger and suits logos, screenshots, and images with sharp edges. WebP offers compact files with good quality, but not every service accepts it.
Watch transparency and backgrounds
When converting a transparent PNG to JPG, empty areas must be filled with a color, usually white. Check the result against light and dark backgrounds before using it, especially for logos that will be placed on a web page.
Export quality affects file size
For JPG and WebP, the quality setting determines the balance between sharpness and file size. Repeated conversions can add further quality loss, so keep one original file and export again from it when needed.

FAQ
Frequently asked questions
Does converting a photo reduce quality?
It can. JPG and WebP generally use lossy compression, while PNG is lossless but larger. Converting from one lossy format to another can also remove detail, so avoid unnecessary repeats.
When should I use PNG?
Use PNG for logos, icons, screenshots, or images with transparency and crisp text. For ordinary photos headed to the web, JPG or WebP usually saves more space.
Can I convert HEIC photos from an iPhone?
HEIC support depends on the browser and operating system. If the file cannot be opened, export it as JPG from the Photos app on your device first, then convert it here.
Can transparency be preserved?
Transparency remains when exporting to PNG or WebP. If you choose JPG, transparent areas are replaced with solid white.
