Image Resizer
Resize images to exact pixel dimensions in your browser.
Every platform wants different dimensions — social posts, marketplaces, CMS thumbnails, ID forms.
About Image Resizer
Resize any JPG, PNG, or WebP image to exact pixel dimensions, with an optional locked aspect ratio to avoid stretching. Useful for meeting upload requirements on social media, marketplaces, or CMS platforms — resizing happens locally in your browser, so photos are never uploaded to a server.
