A free online image resizer that stays private
RightSizeFast is a browser-based image resize tool for JPG, PNG and WebP files. Set custom dimensions or use a ready-made preset, then crop, fit or stretch one image—or resize a whole batch at once. There is no account, no watermark and no file upload.
Resize images in bulk →How do I resize an image online?
Add your image, choose a preset or enter a width and height, select Crop, Fit or Stretch, then download the resized file. Multiple images are delivered together in a ZIP.
Will resizing reduce image quality?
Changing pixel dimensions requires resampling, so enlarging a small image can look softer. PNG uses lossless file encoding; JPG and WebP let you balance visual quality against file size.
Are my images uploaded?
No. Resizing runs locally in your browser, so your images never leave your device.
Does RightSizeFast add a watermark?
No. Your downloaded images are clean and have no RightSizeFast watermark or branding applied.
