Frequently Asked Questions

Can I resize without losing quality?
Downscaling (making smaller) preserves quality well. Upscaling (making larger) may reduce sharpness since new pixels must be interpolated.
Does the tool keep the aspect ratio?
Scale-by-percentage keeps the original aspect ratio. Fixed size and platform presets export the exact width and height you choose, so an image with a different ratio is stretched to fill the canvas. Crop first if you need a different ratio without stretching.
What image formats are supported?
You can resize JPG, PNG, WebP, GIF, and most other browser-supported image formats.
Are the platform presets official requirements?
No. They are common canvas sizes for those placements. Check the target platform's current requirements before upload.
Is there a maximum image size?
Images up to 50MB are supported in the browser.
