Convert Format changes an image between JPG, PNG and WebP right in your browser. Switch a screenshot to JPG to shrink it, convert to PNG for lossless quality, or move to WebP for the best size-to-quality ratio — with a background colour option when flattening transparency into JPG.
Drop your file in; the source format is detected automatically.
Choose JPG, PNG or WebP. If you target JPG from a transparent image, pick a background colour.
Export to save your image in the new format.
