Frequently asked questions
Resize vs crop?
Resize scales the whole image. Crop removes a portion. To change aspect ratio without distortion: crop first, then resize.
What does quality do?
Applies to JPG and WebP only — controls compression level (10=poor/small, 100=perfect/large). PNG ignores quality (lossless).
Can upscaling improve quality?
No — just stretches pixels. For AI upscaling, use a dedicated tool (Upscayl, Real-ESRGAN).
Why does file size grow when I resize down?
Sometimes resampling adds artifacts that compress poorly. Try lower quality or different format.
Maximum dimensions?
8000 × 8000. Beyond that, browser memory issues.
