Convert single or multiple images between JPG, PNG, and WEBP formats with a custom compression quality slider.
Select multiple images (PNG, JPG, WEBP, GIF, SVG)
Pick your target format (WEBP for the best balance of size and quality, AVIF for the newest, most compact next-gen format, JPEG for maximum compatibility with email and older software, or PNG for fully lossless quality with transparency). Then drag and drop as many images as you like into the upload area. Use the quality slider to balance file size and visual fidelity, the resize options to shrink or enlarge a whole batch (e.g. to 50% or to a 1200px max width), and pick a background color to fill transparent areas when exporting to JPEG. Hit Convert & Download Images — a single image downloads directly, multiple images are bundled into one ZIP.

WebP for the smallest files and modern websites (25–35% smaller than JPG with identical quality), JPEG/JPG for the widest compatibility with email clients and older software, and PNG for lossless graphics that need crisp transparency.
Yes — choose PNG for fully lossless output, or keep the quality slider at 90–100% for near-lossless JPG and WebP files where the size savings are usually invisible.
