XnConvert is the best desktop image resizer software for most readers who want a free batch tool on Windows, Mac or Linux, with more than 500 formats to read and more than 80 actions to apply. BatchPhoto is the clearest lifetime licence choice at $29.95 for Home, while reaConverter is an annual licence at $49 per year, so the billing model is the first choice to settle before comparing features. Image-Batch is the best Mac-only choice for small batches, because Lite is free for 3 images at a time, Pro is $8.99 once for 40 images at a time, and Premium is $19.99 once for unlimited images.
Pick by platform first, then by batch size, then by price model. A Windows-only tool is no help on a Mac, a 3-image free limit is no help for 400 photos, and a $49 per year licence costs more over three years than a $29.95 lifetime licence.

The 8 best best desktop image resizer software tools, in detail
XnConvert
Best for: Free batch resizing on Windows, Mac and Linux
XnConvert is a free cross-platform batch image converter from XnSoft, and it is the default pick for most readers because it covers Windows, Mac and Linux in one download. The official page lists more than 500 formats to read and about 70 formats to write, with more than 80 actions that include resize, crop, colour adjustments, filters, watermark and metadata editing. Presets can be saved and reused for another batch, and watch folders can apply a saved set of edits to new or updated images.
- The freeware terms are the point to read with care.
- XnConvert is provided as freeware for private or educational use, including non-profit organisations, and company use is outside those terms.
- The interface is plain and task based, but the format range and presets repay that effort for large collections.
Pros
- Reads more than 500 formats and exports to about 70 formats
- offers more than 80 actions including resize, crop and watermark
Cons
- Company use is not covered by the freeware terms
- export is limited to about 70 formats while reading covers more than 500 formats
FastStone Photo Resizer
Best for: Simple batch resizing on Windows
FastStone Photo Resizer is a focused Windows tool for converting, renaming, resizing, cropping, rotating, changing colour depth and adding text or watermarks in batch mode. The official detail page lists support for JPEG, JPEG2000, PNG, GIF, BMP, TIFF, PCX, TGA, WMF, EMF, ICO, CUR, PPM, HEIC and WEBP on loading, with saving to JPEG, JPEG2000, PNG, GIF, BMP and TIFF. Drag and drop is supported, files can be renamed with sequential numbers, and a preview shows the conversion before it runs.
- The download page states that the tool is free for personal and educational use, and the commercial licence is a separate step for business use.
- The design is plain and the feature set is narrower than a full photo editor, but that narrow focus suits a simple resize job.
- Multithreading helps with a large folder, and saved options let a reader repeat a standard resize.
Pros

- The current download is version 2.8.5, with a Windows installer or portable ZIP for Windows 10 build 1809 or later, and a DMG for macOS 12 or later.
