Open toolCompress images to a target size in KB
Choose one image or a batch, select 20KB, 50KB, 100KB, or 200KB, or enter a custom maximum from your upload form. Every result shows the original size, output size, width, height, and preview before you save it. Check the accepted format and pixel dimensions as well as the file size, especially for photos, signatures, and scanned documents.
Why target KB is easier than guessing quality
Choose a maximum file size instead of repeatedly adjusting a quality slider. For images that need processing, the tool starts with a longest edge of up to 2,400 pixels, adjusts JPG or WebP quality, and reduces dimensions further if needed. PNG uses dimension reduction. Preview the result before downloading; a smaller file can lose detail, and the target may not be achievable for every image.
Which format should you pick?
Use JPG when the website is old or strict. Use WebP when the website accepts modern files and you want a smaller result. Keep PNG for graphics or transparent images, but expect it to be harder to squeeze into tiny limits. The preview makes the tradeoff easy to spot.
A quick workflow that usually works
Check the image size first if you are unsure. Crop empty background if the subject is small, then compress below the upload limit. If the form allows 200KB, use that space to preserve detail instead of forcing 50KB. The default counts 1KB as 1,000 bytes and 1MB as 1,000,000 bytes, so 100KB targets 100,000 bytes. You can choose the optional 1,024-byte unit mode or enter an exact maximum in bytes. Check the actual result size, dimensions, and accepted format before submitting.
