Is there any file size limit or daily usage cap?

No! Because processing happens on your local device hardware, there are no artificial file upload limits, no wait queues, and no premium restrictions.

Does this toolkit add any watermarks to my downloaded images?

Never. All processed images are completely watermark-free, full quality, and ready for commercial or personal use.

How do I compress an image to an exact size like 20KB or 50KB?

Select the "Compress" tab, choose "Target File Size Mode", and select 20KB, 50KB, or enter any custom KB target. Our iterative binary-search algorithm calculates the exact compression parameters to guarantee your file is under the limit without becoming illegible.
