Find Open-Source Image Compressor for Ubuntu/Windows 7

In summary, the person is looking for open source software to compress scanned images for their website. They also need advice on the best format and size for uploading graphs. The suggested software is GIMP and the recommended format is 256 color png or vector graphics (.svg). However, converting from bitmap to vector may not produce the best results.

GIMP comes to mind.

Format depends on the type of graph, in most cases I am using 256 color png (or even less color where possible). No eps, and graphs are usually line art which doesn't get compressed well by jpg, too many artifacts. Max width depends on the page design, but I would not use anything wider than 800 pixels, you don't want people to have to scroll page to sides to be able to see everything.

Graphs would be ideally compressed by vector graphics formats (I.E. .svg) and would scale to larger resolutions without increasing file size. Most browsers support them these days too.

EDIT: Oh, sorry, I should have read better. I didn't realize you had scanned them in. Ideally you'd want to use just the raw data to generate the SVG. Some programs can convert from bitmap to Vector, but it usually doesn't do it in a very intelligent way.

Hello there,

I understand your need for an open-source image compressor for Ubuntu and Windows 7. There are several options available that you can consider.

For Ubuntu, you can try using GIMP (GNU Image Manipulation Program) which is a free and open-source software for image editing and compression. It supports various file formats and has a built-in compression tool that allows you to reduce the size of your images.

Another option for Ubuntu is ImageMagick, a command-line tool for image manipulation and compression. It also supports various file formats and can be used for batch processing of images.

For Windows 7, you can try using IrfanView, a free and lightweight image viewer and editor. It also has a built-in compression tool that allows you to reduce the size of your images.

As for your question about the size and format of your images for uploading, it depends on the requirements of your website. Generally, .jpg or .png formats are preferred for web images, and the size should be optimized for web viewing. You can try experimenting with different sizes and formats to see which one works best for your website.

I hope this helps. Best of luck with your website!
