What it is

MiniPx is a browser-based tool for compressing, converting, and resizing images, with additional tools for background removal, upscaling, and passport photo creation. Its free plan keeps compression, conversion, and resizing unlimited without signup or a daily cap. It accepts JPEG, PNG, WebP, AVIF, HEIC, BMP, SVG, GIF, and TIFF files; free batches are limited to five files. Compression presets are Gentle, Smart, and Tiny, and users can set a target size from 10 KB through 1 MB. Compression, conversion, and resizing run locally in the browser without uploading image files, and outputs remove EXIF metadata such as location and device information. Those core tools work offline after the first page load. Three on-device AI tools share two free runs before a cooldown, and need model downloads on first use. Pro adds unlimited batch processing, text watermarking, presets, responsive exports, and an opt-in cloud path for seven AI tools. The free plan costs nothing. Pro Annual costs $2,939 a year; no monthly Pro price is listed.
