Resize without uploading

Choose an image, enter the new pixel dimensions and export a resized copy. Aspect-ratio locking helps prevent unintended stretching.

When should you resize?

Smaller dimensions can reduce download size and are useful when an image is much larger than its display area. Avoid repeatedly resizing the same already-compressed copy.

Transparency

PNG and WebP can preserve transparency in supported source files. JPG does not support transparency, so transparent areas are filled with white during export.
