Simplifying your workflow with powerful browser-based tools.
Stop resizing images one by one in Photoshop. Select 100 images, set your width to 1200px, and click one button. Get your afternoon back.
Handle large batches without browser lag.
Resize exactly for Instagram, Twitter, and Facebook.
Serving huge 4000px wide images on a blog slows it down. Resizing them to 1000px or 800px significantly improves page load speed and SEO scores.
If you choose "By Width", "By Height", or "Percentage", the aspect ratio is locked, so images will NOT stretch. If you choose "Exact Dimensions" and enter a ratio different from the original, stretching may occur.
Yes! The resizer works perfectly on mobile browsers. You can resize photos directly from your camera roll before emailing or posting them.
