At 100KB, PNG images retain excellent quality and detail while being small enough for most web and form upload requirements. OneWeeb compresses PNG files by intelligently reducing dimensions in small increments until the file fits under 100KB, preserving transparency and lossless quality throughout the process.
A 100KB PNG is perfect for website graphics, transparent logos, UI screenshots, and document uploads. Many content management systems, forums, and e-commerce platforms set 100KB as their PNG upload limit. At this size, even detailed graphics with text and fine lines remain sharp and readable.
Everything runs locally in your browser. Your designs, logos, screenshots, and confidential documents never leave your device. Select your PNG, click compress, and download the optimized file in seconds.
