MB to KB Image Converter

ImgPilot’s MB to KB Image Converter is a free browser-based tool for compressing images to a specific file size. Choose a preset such as 100KB, 200KB, 500KB, or 1MB, or enter a custom target size. The tool adjusts image quality first and resizes only when necessary to produce the closest practical result.

All compression happens locally in your browser, so your images are never uploaded to a server. It supports PNG, JPG, WebP, AVIF, HEIC, and HEIF input files, along with JPG, WebP, and AVIF output. You can compress multiple images at once and download the results individually or together as a ZIP file. No signup is required.
