Frequently Asked Questions
Are my images uploaded anywhere?
No. All resizing happens in your browser. Your images never leave your device.
What happens if I don't maintain aspect ratio?
The image will stretch to fill the exact dimensions, which may distort it. Enable "Lock aspect ratio" to prevent this.
Can I resize to specific social media sizes?
Yes, we include presets for Instagram posts/stories, Twitter headers, LinkedIn, YouTube thumbnails, and more.
What interpolation is used?
Lanczos (high-quality) for downscaling, bicubic for upscaling — automatically selected for best results.
Is there a batch resize option?
Free tier: 2 images. Pro Pass: unlimited batch resize with custom naming.
