Frequently Asked Questions

Do these tools upload my images to a server?
No. All resizing happens in your browser using the Canvas API. Your images never leave your device.
What's the difference between Cover, Contain, and Stretch?
Cover fills the entire canvas by cropping overflow. Contain fits the full image inside with background padding. Stretch distorts the image to fill exactly.
Can I resize multiple images at once?
Yes. Upload up to 20 images and they will all be resized to the selected platform dimensions. Multiple outputs download as a ZIP.
Which format should I use for social media?
JPG is recommended for photos — it keeps file size small while maintaining quality. PNG works better for graphics with text or sharp edges.
