Compress Images to 20KB, 50KB, 100KB, 200KB, 500KB, or 1MB
The target field lets you compress an image to common upload limits such as 20KB, 50KB, 100KB, 200KB, 500KB, 1MB, or a custom KB size. If the file cannot stay clear at a very small target, reduce width or height first and compare the before-and-after preview before downloading.
Bulk Image Compressor With ZIP Download
Add several JPG, PNG, or WebP files when you need a batch compressed together. You can preview each compressed image, download one result, or save every successful output in one ZIP file.
Balance Image Quality and File Size
Smaller KB targets require stronger compression and sometimes smaller dimensions. The comparison preview helps you check whether the compressed image still looks good enough before saving it.
