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.
