Frequently Asked Questions (FAQ)
Is my image resizing private?
Yes! All scaling runs 100% locally inside your web browser using HTML5 Canvas. Your images are never uploaded to any remote server.
How does aspect ratio locking work?
When aspect ratio is locked, entering width automatically calculates matching height (and vice-versa) so your photo never gets distorted.
Can I change the image format while resizing?
Yes! You can choose to keep the original format or export as JPG, PNG, or WebP.
What is the maximum file size limit?
You can resize images up to 50MB per file with unlimited usage.
