When it comes to optimizing jpeg images for faster web page loading speed, there are two compression algorithms – lossy and lossless. Before they dive into that, which is better, Online Jpeg Compression with WordPress Plugin or Desktop Software for optimizing jpeg images? Personally, I prefer downloading ( backing up ) the entire jpeg library, compressing it on my desktop and re-upload it. The reason why I dislike WordPress Plugin is it uses unnecessary resources, downloading for compressing also doubles up as a backup. Lossless vs lossy. Works great on Microsoft’s Windows 10 and Apple’s macOS.
- Lossless compression retains values and manages to lower file size.
- Lossy compression reduces file size by eliminating redundant information.
My favorite Mass and Batch Jpeg Compressor is JPEGmini, it has an impressive algorithm where you can reduce the file size of your photos by up to 5x, while keeping their original quality and JPEG format. I bought the license for JpegMini and all the jpegs on this site are compressed with JpegMini software.

Radical Image Optimization Tool (RIOT for short) is a free image optimizer that will let you visually adjust compression parameters while keeping minimum file size. It uses a side by side (dual view) or single view interface to compare the original with the optimized image in real time and instantly see the resulting file size.
It is lightweight, fast and simple to use, yet powerful for advanced users. You will be able to control compression, number of colors, metadata settings and much more, and select image format (JPG, GIF or PNG) for your output file. RIOT can be integrated as a plug-in in well known programs like The GIMP, IrfanView and XnView.

FILEminimizer Pictures is a software to reduce the size of your images, photos and pictures by up to 98% through their native file optimization technology. After compression, your photos and images are still in your image format and are still beautiful – but a lot smaller in size!
FILEminimizer Pictures compresses JPEG photos, TIFF, BMP and PNG images and pictures by up to 98%. Optimized photos, images and pictures remain in their original format – no need to unzip. Send and share your best photos and pictures easier via email and over the internet.

Removes bloated metadata. Saves disk space & bandwidth by compressing images without losing quality. Downloaded by over half a million people! (15,000 new users a month). ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It’s useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim removes EXIF metadata, such as GPS position and camera’s serial number, so that you can publish images without exposing private information (but there’s an option to keep the metadata if you need it).
- Faster web pages and apps – Reduces image file sizes — so they take up less disk space and download faster — by applying advanced compression that preserves quality.
- Image files scrubbed clean – Removes invisible junk: private EXIF metadata from digital cameras, embedded thumbnails, comments, and unnecessary color profiles.
macOS | Lossless & Lossy
Also known as Lossless Photo Squeezer, Photo Size Optimizer for Mac, a powerful photo resizer and optimizer for macOS, allows you to optimize all your photos by 80% ~ 20% comparing to their originals while keeping their original resolution, quality and png, jpg, gif formats. With Photo Size Optimizer for Mac, you can save huge space and share full-resolution photos with your friends much faster. It supports 70 types of image formats for resizing:

When upsizing images, Photoshop™ Bicubic interpolation produces blurry or diffuse contours. Reshade enhances contour clarity resulting in crisp and sharp details. Noise and artifacts can become more obvious when enlarged. Reshade handles these issues as well with ease. Notice how Reshade enhances and optionally smooths images, bringing out beautiful texture details, sharpening shading and creating clear highlights.
Batch resize and enhance many images at once. Drag and drop entire folders into the application. Reshade will automatically find the optimal settings in each situation.
