About Image Resizer
Resize images online with this free image resizer by setting an exact width or height in pixels or scaling by percentage, with the aspect ratio locked to prevent distortion. Use it to prepare photos for web pages, blog posts, email, social profiles, thumbnails, and upload limits without installing an editor. Download the resized file straight away and keep the original on disk untouched.
Content people resize hero images to a max width. Developers create thumbnails. Sellers meet marketplace pixel rules. Students shrink screenshots for a report. Aspect-ratio lock avoids stretched faces and logos. Percentage scale is handy when you want half size without computing the new width. Pixel size is handy when a CMS demands 1200 by 630 or a similar exact box.
Choose a file, set width, height, or percent, resize, and download. This tool scales; it does not crop to a platform box. For Instagram, YouTube, Facebook, LinkedIn, or Pinterest frames, use Social Size Crop. For a freeform or 1:1 / 4:5 / 16:9 / 9:16 crop, use the Image Cropper.
Resizing happens entirely in your browser, so your photos are never sent to a server. Use this free online image resizer and photo resizer whenever you need accurate, private pixel or percent scaling.
