About the Image Resizer
Need a photo at exactly 1080×1080 for Instagram, 1200×630 for a link preview, or a smaller copy for an online form? This image resizer changes the width and height of any image in seconds.
Lock the aspect ratio to avoid stretching, or use the quick percentage buttons to scale down. Everything happens inside your browser. Your files are never uploaded to a server, so they stay completely private — and it is fast, because there is nothing to upload or download.
How to use the Image Resizer
- Choose an image from your device.
- Enter the new width or height in pixels, or click a percentage button.
- Keep “Lock aspect ratio” on to prevent distortion.
- Choose the output format, click “Resize”, then download the result.
Frequently asked questions
Can I make an image bigger?
Yes, but enlarging cannot add detail that was never captured, so upscaled images can look soft. Making images smaller always looks sharp.
What does “lock aspect ratio” do?
It keeps the original width-to-height proportion, so when you change one dimension the other updates automatically and the picture is not stretched.
What image sizes do social networks use?
Instagram post 1080×1080, Instagram story 1080×1920, Facebook and LinkedIn link image 1200×630, YouTube thumbnail 1280×720, X (Twitter) post image 1600×900.
