Frequently Asked Questions
How do I resize an image?
Upload your image, enter the desired width and height in pixels, or use a percentage to scale. Toggle 'Keep aspect ratio' to maintain proportions.
Does resizing affect image quality?
We use Lanczos resampling which provides the best quality for both upscaling and downscaling images.
What image formats are supported?
JPG, PNG, WebP, GIF, BMP and TIFF formats are supported. Output keeps the original format.
Can I resize without changing the aspect ratio?
Yes. Enable 'Keep aspect ratio' and enter only one dimension â the tool automatically calculates the other to maintain proportions.
Are my files secure?
Yes. All uploads are automatically deleted after 1 hour. We never store or share your files.
Is there a file size limit?
Images up to 50MB are supported. Larger files may take longer to process.
Will my original image be overwritten?
No. Your original file is never modified. You download a new resized copy, and all files are deleted from our servers after 1 hour.
