Compare RedKetchup vs. TinyPNG

You can easily resize, convert, or compress multiple images in one go by browsing for and selecting the files or folders you wish to work with; simply drag and drop the images or select a zip file containing them. Alternatively, you can paste an image directly from your clipboard, though keep in mind that the operation is limited by your system's available memory. Each image will be processed separately, but be prepared for the memory requirement to be 3 to 4 times larger than the combined size of the images when they are downloaded as a zip file. The image processing is executed via JavaScript, and note that the browser may limit CPU resources for tabs that are not currently in focus, so it's best to keep the browser tab active to speed up the process. For optimal results when compressing PNG or BMP files, adjust the color depth to 8-bit, while for JPEG, WEBP, or HEIC formats, lowering the quality setting will help reduce file size. In the batch configuration area, you can either choose a predefined task or customize each option as needed. After processing, you can easily review the images by expanding the list, and by clicking on a file name, you can view the respective image in detail. This user-friendly interface allows for efficient image management and editing, making it a versatile tool for your image processing needs.
