Optimize signature or fingerprint image
Choose a target maximum file size. This browser-only tool searches JPEG quality and, if needed, image resolution, then downloads the best result it can fit under the target. Original files are not uploaded.

Output is JPEG and may be smaller than the requested maximum. Matching an exact byte count is not guaranteed; very small targets may not be achievable.
Output is JPEG, so transparent input is composited onto white. Free use is limited to 3 downloads per day. Upgrade options. Daily-use counters remain on this device; account Pro status is checked with the server.
