SunlitGreen BatchBlitz is a free, powerful and easy-to-use photo categorizer, file filter and batch editor. It provides an intuitive and efficient way to categorize and batch process your digital photos. The use of regular expressions and actions make the tool extremely flexible and powerful. BatchBlitz lets you batch-process your photos using customizable actions. You can save your action settings to a task file and reuse it later. Actions allow you to filter source files (using regular expressions, for example), rename and convert images, as well as add watermarks, resize/rotate canvas, apply automatic color corrections, etc. The instant preview will give you a better idea of the actual effects. In a typical batch processing task, you simply select some source images, specify where and how to store the output files, define one or more actions, and then start the task with a click.

Image editor, like PaintBrush or Paint.Net, written in Lazarus (Free Pascal). Includes BGRABitmap, a set of drawing routines. Features: antialiasing, multiple undo, alpha blending, BGRABitmap, selection of any shape, rotation, filters, update checker. It has new features: printing, curve adjustments, image list, texture on 3d objects, etc. LazPaint was started to demonstrate the capabilities of the graphic library BGRABitmap. It provides advanced drawing functions in Lazarus development environment. Both provided a source of inspiration for the other and finally LazPaint became real image editor.

Archiver of JPEG-pictures to smaller JPEG XL files (*.jxl)! You can add to archive or extract your original photos from archive. Lossless JPEG transcoding - about 20% smaller. Existing JPEG files can be losslessly transcoded to JPEG XL, significantly reducing their size. These can be restored into the exact same JPEG file, ensuring backward compatibility with existing JPEG-based applications. These features are intended to provide a smooth transition from legacy JPEG platforms to the modern JPEG XL. Both the transcoding and restoration are computationally efficient. JPEG XL is a modern image format that provides superior lossy and lossless compression for images. Using JXL, webmasters and web developers can create smaller, richer images that make the web faster. It uses program cjxl.exe. Batch processing of files (drag-n-drop). Program optimizes your file to new one with «_optimized» name ending (source file will remain intact). Reduce the size of your image files in one click with or without quality loss!

Lightweight yet powerful photo enhancer and editor. Drag and drop to open photo files. Photo viewer with easy-to-use zoom tools. Editable and savable image selections. Automatic color corrections. Advanced, channel-oriented color corrections. Previewable image adjustments. mage filters for creating special effects.

FastStone Photo Resizer is an image converter / resizer intended to enable users to convert, rename, resize, crop, rotate, change color depth, add text and watermarks to images in a quick and easy batch mode. Drag and Drop mouse operation is well supported. Support JPEG, BMP, GIF, PNG, TIFF and JPEG2000.

Convert your pictures JPEG/PNG in smaller WEBP files (up to 10-50%)! High compression ratio — better than your programs / photo camera or smartphone. WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster. It uses program cwebp.exe from Google. Batch processing of files (drag-n-drop). Reduce the size of your image files in one click with ot without quality loss! Program optimizes your file to new one with «_optimized» name ending (source file will remain intact). WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.

MyPaint is a fast and easy open-source graphics application for digital painters. It lets you focus on the art instead of the program. You work on your canvas with minimum distractions, bringing up the interface only when you need it. MyPaint comes with a large brush collection including charcoal and ink to emulate real media, but the highly configurable brush engine allows you to experiment with your own brushes and with not-quite-natural painting. Before beginning it is a good idea to read the quick-start tutorial to see how the program is meant to be used.

Optimize and convert your pictures PNG, FLIF, PPM, PAM, PNM, PGM, PBM in smaller FLIF files (up to 10-30%)! Full compatible with original FLiF format. High compression ratio — usually better than flif original (without tuning). Flif Optimizer tries many compression options and chooses the best result! Batch processing of files (drag-n-drop). Fast and Ultra modes for repacking! Reduce the size of your image files in one click! FLIF — Free Lossless Image Format. FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms of compression ratio. Program optimizes your file to new one with «_optimized» name ending (source file will remain intact).

Optimize and convert your pictures and photos JPG, JPEG in smaller JPG files (up to 10-20%) lossless! Full compatible with original JPEG format. High compression ratio — usually better than your programs / photo camera or smartphone. It uses program «jpegtran.exe» from MozJPEG. Batch processing of files (drag-n-drop). Reduce the size of your image files in one click without quality loss! Program optimizes your file to new one with «_optimized» name ending (source file will remain intact).
