Image Resize changes photo and graphic dimensions directly in your browser, one file or up to 36 images at a time. It is useful when a website, app store, marketplace, CMS, or social platform needs an exact width, a smaller file, or a standard preset size.
Use By Pixels when the output needs a specific width or height. Use By Percentage for quick proportional scaling. Use Fit To when an image must fit inside a box or fill a target canvas for thumbnails and social previews.
Original keeps the closest browser-supported format from the source image. JPG and WebP use the quality slider; lower values make smaller files, while higher values preserve more detail. PNG is best for transparent graphics and crisp UI assets. When you resize multiple images, download individual outputs or export everything as one ZIP.
Files stay on your device. For more image edits, try Rotate Image, Flip Image, or Image Converter.
No. The uploaded file is decoded and resized in your browser with canvas. AppKiro does not send it to a server.
Yes. Keep Maintain aspect ratio enabled in pixel mode, use percentage mode, or choose Fit To with Contain.
Browser canvas exports a still image from the decoded frame. Use this tool for static image resizing, not animated GIF preservation.
Use Original when you only need new dimensions, JPG for small photo files, PNG for sharp graphics or transparency, and WebP for a modern balance of quality and size.
