Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How does this client-side image resizer work?
It uses the browser's Canvas API to scale your images to absolute dimensions (width and height in pixels) or relative ratios (percentages). The rendering and scaling are performed entirely on your local CPU/GPU.
Can I resize images without losing aspect ratio?
Yes, the resizer includes a 'Lock Aspect Ratio' feature that automatically calculates the proportional height when you change the width, or vice versa, preventing visual stretching.
Does resizing an image upload it to the cloud?
No, the resize operation happens fully offline in your browser. Your images are secure and never sent to any server.
What image formats can I resize?
You can resize standard formats such as JPEG, PNG, WebP, GIF, and SVG files.
