Frequently Asked Questions
How do I resize an image to exact dimensions?
Enable the 'Resize Output' toggle, enter your exact width and height in pixels, and uncheck the aspect ratio lock if you want exact measurements regardless of distortion.
Can I compress an image to under 100 KB?
Yes! Check the 'Target File Size' option and enter 100. The tool automatically adjusts JPEG/WebP quality to ensure the file stays below your limit.
Is my image uploaded to a server?
No. All cropping, resizing, and compression runs entirely in your browser using local processing. Your image never leaves your device.
