❓ FAQ
Yes. Enlarging an image beyond its original size requires pixel interpolation which results in blurriness (upscaling). Downsizing (downscaling), however, has minimal quality impact. For AI-enhanced upscaling, specialized tools are recommended.
When enabled, changing the width automatically adjusts the height to maintain the original aspect ratio (and vice versa). This prevents the image from appearing stretched or distorted. Uncheck to set width and height independently.
Instagram recommends 1080×1080px for square posts, 1080×1350px for portrait, and 1080×566px for landscape. Stories should be 1080×1920px. Use the presets to quickly apply these dimensions.
No. All resizing is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
The resized image is downloaded as PNG regardless of the original format. If you need a different format, use the Image Converter after resizing.
