Resize Image Online
Last updated: August 2026
Change the width, height, or scale of an image in seconds — right in your browser. Upload or scan an image, set the target width, height, or percentage, and ScanTo produces a resized copy locally on your device. Nothing is uploaded and no account is required.
Resizing is the standard way to meet strict image requirements — for forms, marketplaces, and social media that reject oversized photos. Because processing is local, you can test different sizes as often as you like without uploading anything.
Frequently asked questions
Is the image resizer free?
Yes — resizing images is completely free with no login and no watermark.
Will resizing reduce the image quality?
Only when you scale the image down or raise the compression. Keep the aspect ratio locked to avoid distortion.
Which formats are supported?
JPG, PNG, WebP and AVIF in and out. SVG and GIF files are not processed by the resizer.
