What image formats are supported for resizing?

The image resizer supports all major formats including JPEG, PNG, GIF, WebP, BMP, and TIFF. You can upload any of these formats and export in your preferred format.

Will resizing reduce image quality?

Downsizing images preserves quality well. When enlarging, the tool uses smart interpolation to minimize pixelation, though enlarging beyond the original resolution will always reduce sharpness. For best results, start with the highest resolution source available.

Can I lock the aspect ratio when resizing?

Yes. The aspect ratio lock is enabled by default. When you change width, height updates automatically to maintain proportions. Unlock it to resize to non-proportional custom dimensions — useful for social media image specifications.

Are my images uploaded to a server during resizing?

No. All image resizing happens locally in your browser using the Canvas API. Your images are never uploaded to any server, ensuring complete privacy.
