darktable is an open source photography workflow application and non-destructive raw developer - a virtual lighttable and darkroom for photographers. It manages your digital negatives in a database annd lets you view them through a zoomable lighttable and enables you to develop raw images, enhance them and export them to local or remote storage. It focuses on the workflow to make it easier for the photographer to quickly handle the thousands of images a day of shooting can produce. It is one of the very few FOSS projects that supports tethered shooting.

JPEG Lossless Rotator is an application for rotating JPEG files performs a special "lossless" algorythim using block transformation without a decoding and re-encoding process, which preserves the image quality. If the image can't be rotated without losing some pixels, the program will prompt you with the costs in pixels.

Features batch and automatic rotation, image flipping, renaming and deletion of files, and display of EXIF-data.

RIOT (Radical Image Optimization Tool) presents a before-and-after image compression view that allows you to reduce file size of an image into JPG, PNG, or GIF format. Includes optional metadata removal, batch operations, compression to a target file size, transparency options, and other common editing functions (flip, rotate, zoom, pan). Notable versus similar software in the ability to gradually reduce the available colors one-by-one (7, 8, 9, 10...), not just milestones of 16, 32, 64 etc.

The program is also available as a plugin for XnView, GIMP, or Irfanview (see website).

Functional in Linux using Wine. Many of the official entries here on PortableFreeware have used RIOT for compression. Note that the installer version of this program is considered adware.

ImBatch is a powerful image processing tool with a long list of available tools for modifying one or more files. Available options include resize, rotate, modify colors, metdata, blur, shadow, crop and many more. Tasks can be chained (e.g. adjust contrast + sharpen) and reordered to just preview not just one change but multiple edits. Any process can be saved for quickly assembling future edits.

The program can also optimize images, create or add to an existing PDF, create animations (GIF), and upload the results to a remote server. The program can also passively watch a given folder for images to process and longer operations can put the computer in standby to save power once they conclude.

Smart functions include autocrop, auto-enhance, auto-stitch (for panorama-type images). The program supports a wide range of formats, command-line operations and batch task settings for easy load/unload of operations.

PngOptimizer is an easy-to-use program to compress common graphics formats to PNG format with no quality difference. Files can be added one at a time or in batch to the program icon or window. Images can also come from the clipboard by pressing CTRL+V while the application is in focus.

Cross-platform with clients available for Linux. A CLI version is available.

Graphics formats supported include BMP, GIF, TGA, as well as further compressesing PNG files. Animated GIF and PNG files (APNG) are also supported. Size decrease for PNG files varies widely on the original editor, but GIF and BMP conversions can be as much as 40% and 95% respectively.

Alternatively, PngOptimizer Portable automatically switches between 32-bit and 64-bit and adjusts the screenshots path.

Xlideit Image Viewer bundles an image, document and video viewer with a basic graphic editor. The interface is customizable to show groups of thumbnails and subfolders. Edition tools include crop, rotate/flip, convert and tag viewer/editor. Includes additional options to generate slideshows.

Raw Therapee is cross-platform RAW image file processing program. It compares well with its more expensive commercial counterparts such as Adobe Photoshop, Lightroom, Bibble Pro, etc., but its user interface has a steeper learning curve.

Raw Therapee lets you apply color correction, image sharpening, and retouching to your RAW image files in a non-destructive way. Its image sharpening algorithms appear to be superior to some of its commercial peers, and its color correction features lets you make adjustments to a deeper level than similar programs.

Beyond color correction, RawTherapee also provides other in-depth options ror RAW file corrections. This includes things such as pre-processing, pattern noise and chromatic aberration correction. Batch editing is also supported within the File Browser tab.

Picture Resizer is a single-EXE, high speed batch JPG resizer. The tool sits on the Windows desktop and resizes JPG images sent to it via drag-and-drop. The resized image files are saved in the same folder as the original files. Names of the new pictures will be based on the original names, with a suffix indicating their size. For example, the resized version of MyPhoto.jpg will be called MyPhoto-400.jpg, where the number 400 indicates the size of the picture.

What is unique about this program is that there are no settings to speak of. The desired final size is set by renaming the EXE. For example, PhotoResize800.exe means maximum width/height of 800 pixels, PhotoResizeP50.exe means 50% of original size and so on. There are too many variations to fully list here.

For further customization, you can also add command line arguments to the executable shortcut. They allow you to change the output folder, specify the JPEG quality factor etc.

LazPaint is a full-featured image and photo editor with support for layers, drawing tools, filter effects, rendering textures and more.

jpgQ is an image analysis tool that can estimate the quality settings used to save a JPEG image. Since it's difficult to determine the compression level without access to the original, this program can help determine the value (between 1 and 100).

Useful for editors interested in seeing if a JPEG edit will drastically reduce quality, since higher numbers are more likely to survive another instance of lossy compression without serious degradation.

JPEG & PNG Stripper is a drag-and-drop metadata stripper/cleaner for one or more JPG/JPEG, JFIF and PNG files, saving disk space and protecting privacy. Metadata carries a variety of information about the camera or device used to take the picture, date it was taken, and other data primarily important for photographers. Because metadata increasingly carries more and more information about the pre-cropped original photo and on where the picture was taken (geo-location), metadata can represent a privacy risk. Deleting metadata usually saves between 1 and 10% of the overall file size.

The program includes a "preview only" feature to show how much space image metadata is taking up.

HTML Image Page Builder takes an image and converts it to text in an HTML page that still looks like the original image. The text of the HTML page can be binary, numbers, random characters or part of a proper text file.

TIFFsy Turvy extract multi-page TIFF files, apply rotation and export to JPG or PDF in one step. Handy when you get multi-page faxes in TIFF format that are upside-down.
