Image Compressor
Compress images to 20 KB, 50 KB, 100 KB or a custom size. Optimize JPG, PNG, WebP and AVIF with before-and-after comparison and batch downloads.
Smaller files. Sharper results.
Compress images to 20 KB, 50 KB, 100 KB, 200 KB or any size you choose. Fine-tune the format, compare details and download your files.
Choose an image, set its target size and compare the original with your result.
Compress images to a specific size in KB
Set a file size such as 20 KB, 50 KB, 100 KB, 200 KB or a custom limit. Image Compressor evaluates multiple quality levels, then reduces dimensions when Smart Fit is selected and the target cannot be reached at the original size. It aims for the highest practical image quality under your chosen limit.
Compress JPG, PNG, WebP and AVIF files
Keep your image format, switch formats manually, or select automatic format choice. JPEG is ideal for everyday photographs; WebP usually offers efficient compression; PNG preserves lossless pixels and transparency but may need smaller dimensions to satisfy a tight limit. AVIF availability depends on your browser.
Compare before and after
Review each original image beside its compressed version with the interactive comparison control. See the original size, resulting size, output dimensions and percentage change before saving.
Compress multiple images at once
Select up to 24 images, apply a target size and download files separately or together in a ZIP archive. If a target is technically unattainable with the selected settings, the result is clearly marked rather than reported as an exact match.
