Solvium Image Optimizer (IO) is a desktop application that can help you to optimize, compress, convert and resize image files easy and convenient. The program currently supports three basic formats of web graphics: .PNG, .JPEG and .GIF and uses only the best and proven techniques for file size reduction. With a full set of options you can choose your own way to optimizing images: fast or thorough, lossless or lossy, with resizing or not and much more.

Images optimization and compression can help in many ways:

Improve loading times and speed of your web pages, e-mail newsletters or WordPress blogs
Boost your grade in tools, that analyzes page’s speed performance
With the small images you will get faster backups
Achieve a greater ranking in the search engines because your site is loading faster
Reduce the final size of your themes or templates, desktop or web UI, iOS or Android apps
Save valuable space on your hard drive or hosting, decrease the bandwidth usage
Bring the user experience to a new level

Current version: 1.2.0

Please, report all bugs and issues and they will be fixed in the new version. You can also ask to add new features.

Complete List of Features

No restrictions on max file size: unlike the most web services that limit the size of files and take a subscription fee

Batch processing: you can drag and drop files from any place of your computer and optimize them at once

Two-step file size reduction: optimization plus compression
- Optimization will try to organize the palette in your image, makes automatic selection of the optimal format, uses advanced heuristics for filters.
- Compression will try to use advanced compression algorithm to reduce the file size even more, and what important AFTER optimization, so you achieve the best possible results.

PNG:
- Optimization:
  - RGB color space cleaning
  - palette optimization
  - best choice of colortype
  - bit depth reduction
  - colors quantization, etc.
- Compression:
  - recompress DEFLATE stream
- Option to choose optimization strategy: 1 of 5 presets
- Option to choose compression level: 1 of 6 presets

JPEG:
- Lossless or lossy results with compression
- Stripping of all unnecessary metadata
  - EXIF
  - IPTC
  - XMP
  - ICC color profile
- Option to choose compression quality (from 60% to lossless)
- Options to disable stripping metadata
- Option to save JPEG as progressive

GIF:
- Animated gifs support
- Option to choose optimization mode: 1 of 3 presets
- Option to write larger GIF to avoid possible errors
- Option to strip excessive transparency
- Option to strip all unnecessary metadata

Resizing:
- Ability to select multiple sizes while resizing
- Ability to add custom sizes for resizing
- Ability to choose one of 30 filters for resizing (ImageMagick’s):
  1. Bartlett
  2. Blackman
  3. Bohman
  4. Box
  5. Catrom
  6. Cosine
  7. Cubic
  8. Gaussian
  9. Hamming
  10. Hann
  11. Hermite
  12. Jinc
  13. Kaiser
  14. Lagrange
  15. Lanczos
  16. Lanczos2
  17. Lanczos2Sharp
  18. LanczosRadius
  19. LanczosSharp
  20. Mitchell
  21. Parzen
  22. Point
  23. Quadratic
  24. Robidoux
  25. RobidouxSharp
  26. Sinc
  27. SincFast
  28. Spline
  29. Triangle
  30. Welch
- Ability to choose 1 of 4 resizing methods:
  - Fit to box: New image will fit into the requested size. Width and height will be calculated based on your settings.
  - Constrain proportions: Resizing will be based on the smallest fitting dimension and preserved original aspect ratio. Width and height will be calculated based on your settings.
  - Crop: Crop image and align to center. Good for making thumbnails.
  - Exact: Shrink or enlarge image if it necessary, but not constrain proportions.
- Ability to set output filename by patterns and generate all sizes of thumbnails at once (for WordPress for example):
  - If the original filename for example, background.jpg and you will resize it to 1024×768 and use pattern [{width}x{height}] – {filename}{ext} then the new resized filename will be [1024×768] – background.jpg.

Export files to external folder or overwrite them
Image format converting with further optimization
Works with network mapped hard drives
Backup existing files: you can make a copy of the every file that going to be optimized
Save original timestamp: copy date and time of creation from original file to optimized filed
Save a text report after each optimization
Main window can work in compact mode, where advanced options is hided
Longlife updates and support with new functions in future
