How to Use Image Resizer

- Download Resized Photo: Click 'Resize Image' to render the output canvas and download your newly dimensioned photo.
Frequently Asked Questions
What does the aspect ratio lock do?
When aspect ratio lock is enabled, typing a new width automatically computes and adjusts the height proportionally to avoid distortion.
Can I resize by percentage instead of exact pixels?
Yes. Select the 'By Percentage' tab to scale the image up or down (e.g. 50% for half size, 200% for double size).
What social media presets are available?
We provide one-click presets for 1080x1080 (Instagram Square), 1080x1920 (Stories/Reels), 1200x630 (Facebook/OpenGraph), 1920x1080 (Full HD), and more.
Can I change the output format while resizing?
Yes. You can convert the resized output to JPG, PNG, or WebP using the Output Format dropdown.
Will resizing a photo make it blurry?
Scaling an image down maintains sharp quality. Scaling an image up beyond its native resolution can cause pixelation because the browser must interpolate missing details.
Are my resized pictures uploaded anywhere?
No. Resizing is performed 100% client-side in your browser.
