Resize Images Online

Scale photos, banners, and digital graphics to exact pixel dimensions, percentage ratios, or standard formats for social media, website publishing, and official documents.

FileVance Image Resizer provides pixel-accurate dimensional scaling powered by HTML5 Canvas bicubic interpolation. Enter custom width and height values in pixels, toggle aspect ratio lock to prevent image stretching, or use percentage scaling. When entering custom dimensions that differ from original proportions, the interactive crop overlay lets you position the crop frame precisely. Choose your preferred output format (JPG, PNG, or WEBP) and adjust compression quality.

Frequently Asked Questions

Will resizing my image cause blurriness or distortion?

Downscaling images retains crisp clarity through browser bicubic interpolation. When resizing to new aspect ratios, lock the aspect ratio or use the crop-to-fit mode to prevent unnatural stretching.

Can I resize an image by percentage instead of exact pixels?

Yes. You can scale down or scale up using percentage increments or by entering exact pixel measurements.

Which image formats can I upload and export?

You can upload JPG, PNG, WEBP, and GIF images. Resized outputs can be exported in standardized JPG, lossless PNG, or lightweight WEBP formats.

Are my photos uploaded to any server during resizing?

No. All rendering and dimension calculations are handled locally within your browser using HTML5 Canvas. Your photos never leave your device.

What is the maximum image resolution I can resize?

Because processing runs in client memory, FileVance easily handles high-resolution smartphone and camera photos up to 100 megapixels.
