Resizer to 20kb

Resizer to 20kb focuses on reproducible image size reduction for web delivery. It accepts common image formats, applies perceptual compression, and aims to reach an exact or near-exact final size of 20 kilobytes. The tool is designed for developers, content teams, and site operators who must meet strict bandwidth or hosting constraints while preserving essential visual clarity.
Conceptually, the tool balances quality and dimensions. It estimates a starting quality, iteratively compresses, and, if necessary, reduces width and height to approach the target. Metadata stripping and format options help further reduce size. The process is deterministic for a given input, producing the same target result under the same settings, which aids automation and versioning in deployment pipelines.
Benefits include faster page loads, lower bandwidth costs, and consistent media assets across a site or CMS. Use cases span product thumbnails, blog hero images, email attachments, and social previews where a fixed file size is required. By focusing on a single target size (20kb), teams can standardize image assets and simplify content workflows without manual trial-and-error tuning.
Core features include input validation, target-size tracking, and an output report. Optional constraints like maintaining aspect ratio and format preference give flexibility. The tool emphasizes transparency by reporting final size, applied width/height, and quality metrics alongside the resized file.
