OrbConvert converts your image files online. Amongst many others, we support PNG, JPG, JPEG, WEBP, GIF, SVG and TIFF. You can use the options to control image resolution, quality and file size.

Keeps every pixel, so nothing is lost when you save or re-save it — the safest choice for screenshots, logos and sharp-edged graphics. Photos stored as PNG are usually much larger than the same photo as JPG.

Compresses harder than anything else we support, so it wins whenever file size matters most. Support is still patchy, so keep a copy in another format.
