Obraz czarno-biały FAQ
Are images uploaded to ResizeWizard?
No. The editor uses browser APIs and canvas processing where possible, so images stay on your device.
Can every browser export AVIF, TIFF, or GIF?
No. ResizeWizard shows those formats where requested, but export depends on browser canvas support. If unsupported, choose JPG, PNG, or WebP.
Can I keep editing after one change?
Yes. After previewing an edit, the preview becomes the current working image, so you can continue with another tool.
