This image compressor tool supports JPG, JPEG, and PNG format for compression without losing nature of image. It lets you upload a maximum of 50 MB images for compression. Uploaded files will remain there for complete 24 hours. Trimage image compressor – 1.0.5 A cross-platform tool for losslessly optimizing PNG and JPG files. Trimage is a cross-platform GUI and command-line interface to optimize image files for websites, using optipng, pngcrush, advpng and jpegoptim, depending on the filetype (currently, PNG and JPG files are supported).

Image Compression Tool for Windows 10 Image Compress Tool is perfect for who wants to save space on your computer by compressing your photos/images.

When you're looking to boost your website's performance, some would recommend you jump straight into a detailed analysis of each page: the HTTP requests you're making, any redirects involved, the position of scripts and style sheets, and more. But while there's no doubt that examining these issues can help, it's important to consider the basics first. In particular, are you sure that any graphics you're using are fully optimised for the web?

You've probably already made sure to choose the appropriate format for each image as well as keeping its size (in pixels) to a minimum. Maybe you've reduced the JPEG quality setting as much as you can. (Although if you're not quite confident in your knowledge of the fundamentals then the may help.) The unfortunate reality is that, no matter how carefully you design your images, the graphics tool you're using will not save the finished files in the most efficient way. And so passing those images through a compression tool can reduce their size considerably. Exactly how much you can save is tricky to say for sure as it depends very much on your source graphics.

Some JPGs may only drop by 50-100 bytes. It's not unusual for regular web graphics to be compressed by 10-40 per cent, though, with no loss of image quality (and lossy compression techniques, perhaps reducing colours or reencoding JPEGs can cut file sizes even more). Testing Which programs are the best, then? Good question.

To help provide an answer we've pitched 18 of the top contenders against each other. The bulk of these are Windows-based lossless compression tools as they're the most interesting (reducing file size without reducing image quality is a very appealing idea). But we've also included lossy compression options, Mac programs and web services, so there really is something here for everyone. We then asked every package to compress the same sets of GIF, PNG and JPG images, each of which were actual web graphics we'd found on a range of real sites, and made a note of the savings. We checked the programs for other issues, too.
