About Reduce Image Size in KB

Last updated: 2026-10-05

Reduce Image Size in KB is an independent tool built and maintained by a solo developer who makes small, single-purpose web utilities. Images are processed in your browser and are never uploaded or stored on a server. If a file comes out wrong for a form you are filling in, email us the limits the form asks for and we will look at it. HEIC photos are decoded with the open-source libheif library (LGPL-3.0, via the heic-to package), loaded unmodified only when you open a HEIC file.
