MiniPx vs XnConvert — 500 Formats or No Install — Free, Fast & Private
XnConvert is a serious piece of software. It reads more than 500 formats, exports to about 70, and applies over 80 actions — resizing, rotation, colour adjustments, watermarks, filters — across an unlimited batch, locally, on Windows, macOS or Linux. For private and educational use it is free.
If your problem is “I have 4,000 files in eleven formats and need them all converted with three transformations applied”, XnConvert is the better tool and this page will not argue otherwise. Browser tools do not compete at that end.
What MiniPx is for instead
The common case is narrower than XnConvert’s design: a handful of images that need to be smaller, in a format a website or a portal accepts, right now, on whatever device is in front of you. That is where an install, a settings tree and an action pipeline are friction rather than power.
MiniPx opens in a tab, has no configuration to learn, and runs on a phone. Its format range is deliberately narrower — JPEG, PNG, WebP and AVIF out, with HEIC, TIFF, SVG, GIF and BMP among the inputs — because those cover what browsers, marketplaces and government portals actually accept.
The licence detail worth knowing
XnConvert is freeware for private and educational use; commercial use is licensed separately. Worth checking before you standardise a studio or an agency on it. MiniPx is free to use commercially, with a 5-file batch cap on the free tier and Pro for unlimited batches.
Choosing between them, briefly
Deep format coverage, complex transformations, thousands of files, on your own desktop: XnConvert. A few files, a destination with a rule attached, a device you cannot install on, or a phone: MiniPx.
