FAQ
Are my images uploaded?
No. Resizing runs in this browser and the new files are created on your device.
Why create several widths at once?
Responsive websites serve different sizes to phones and desktops with srcset. Enter widths such as 1920, 1280, 640 to get every size in one step.
Does resizing lose quality?
Images are downscaled in steps with high-quality smoothing to keep them sharp. Enlarging beyond the original size cannot add detail, so it is off by default.
What formats can I export?
You can keep the original format or convert to PNG, JPG or WebP while resizing. Quality is adjustable for JPG and WebP.
What is the maximum file size?
Up to 50 MB per image. You can resize multiple images at once and download them all in a ZIP file.
