Frequently asked questions

No. Everything runs entirely inside your browser using your own device — your files never leave your computer or get uploaded anywhere. That makes it private and fast, even for large files.
Keep the aspect-ratio lock on, or use “Fit inside” so the whole image is preserved. “Crop to fill” fills the exact dimensions by trimming the edges, which is ideal for fixed-size social posts.
Yes — use a preset (e.g. 1080×1080 for square, 1280×720 for 16:9) or type any width and height you need. The tool warns you when your target ratio differs from the source.
It can, but enlarging beyond the original resolution will look soft because there’s no extra detail to add. For best results, resize down rather than up.
Yes, completely free with no sign-up, no watermark, and no daily limits. Use it as much as you like.
