Reduce image dimensions
Decrease your image sizes to fit your web, email or social media needs. Yes, but enlarging an image may reduce quality. Enlargement may pixelate the image depending on the scale factor. We recommend not exceeding 200% of the original size. Automatically preserve the original aspect ratio or choose custom proportions in pixels. Also discover our tool to crop an image.
Resize for social media
Adapt your images to the formats required by Facebook, Instagram, Twitter and LinkedIn. Get optimized dimensions for every platform to maximize display quality and engagement on your posts. When working on resizing, check the change where detail actually matters. This catches outliers without turning every file into a separate job.
Free resizing without signup
No signup, no email required. Reduction preserves quality. Before you accept the resizing result, compare it with the source file. Keep the source and the finished file under distinct names so you can return to the untouched image later instead of rebuilding it from an already modified copy.
Secure and confidential processing
Your images are resized directly in your browser. No files are sent to a remote server. Resizing done in your browser. No data transmitted. Yes, upload multiple images and they will all be resized with the same settings. Enable the "Keep proportions" option and only the modified width or height will automatically adjust the other.
Check the final dimensions
Use our preset dimensions for Instagram, Facebook, Twitter, and LinkedIn. Get the perfect size for each platform. For thumbnails, 300-400px. For web, 1920px wide maximum is usually enough. After resizing, open the exported file and check it in its final context. That keeps each new attempt easy to judge and undo.
