Which image format should I choose: JPG, PNG or WebP?
Choose JPG for photographs and smaller files, PNG for graphics, logos and transparency, and WebP for modern websites where smaller files matter. WebP often beats JPG on size at similar quality, while PNG stays best for sharp text and images that must not lose detail.
What happens to transparency when converting to JPG?
JPG has no transparency, so transparent areas become a solid background color. Use the background color picker on this page to choose white, black or a brand color before converting, then check the preview to make sure the result looks right for your design.
Are my images uploaded during conversion?
No, conversion happens entirely in your browser. The file is read locally, drawn to a canvas and exported in your chosen format, so nothing is sent to a server. Your images stay private on your device from start to finish.
Will converting change my image quality?
Converting to PNG is lossless and keeps full quality, while JPG and WebP use lossy compression that can soften fine detail at low settings. This tool uses high quality for JPG and WebP, and keeps the original dimensions, so visible quality stays close to the source.
