Frequently asked questions
Will resizing reduce image quality?
Shrinking an image (downscaling) has minimal quality impact. Enlarging (upscaling) can cause blurring because pixels are being created from nothing. For best results, always work from the highest resolution original.
Can I resize without changing aspect ratio?
Yes — enable "Lock aspect ratio" and changing either width or height will automatically update the other dimension to maintain the original proportions.
What is the maximum image size supported?
There is no strict limit but very large images (over 20MP) may be slow on older devices since processing happens in your browser. For best performance, use images under 10MB.
Does resizing work on PNG images with transparency?
Yes. PNG files with transparent backgrounds are resized correctly and the transparency is preserved in the output when you choose PNG as the output format.
