FAQ
Image resizing questions
Does this upload my images?
No. The image is opened and resized in your browser with canvas, so your file is not uploaded to Code Card.
Can I resize an image by percentage?
Yes. Choose percent mode to scale the original image from 10% to 200% while keeping the same aspect ratio.
Which export formats are supported?
You can export the resized image as JPG, PNG, or WebP. JPG and WebP include a quality slider for smaller files.
How do I avoid stretching a photo?
Keep aspect-ratio lock enabled when entering custom pixel dimensions, or use percent scaling to preserve the original proportions.
