How can I verify the image isn't uploaded?

Open your browser's DevTools (F12) and go to the Network tab. Resize an image while watching for requests. No outbound connections appear because all processing happens locally in your browser tab using the Canvas API.

Why resize images without uploading?

Some files are not appropriate to send to a third-party service, and some networks block uploads altogether. Resizing locally avoids both problems.

Will resizing reduce my image quality?

Reducing dimensions generally preserves quality well. Output quality also depends on the format: PNG is lossless, JPEG uses compression that can affect quality at lower settings.

Which image formats are supported?

JPEG, PNG, and WebP are supported as inputs. You can download the resized result as JPEG or PNG.
