How it works
Upload an image and enter your target width and height in pixels. Optionally lock the aspect ratio to avoid distortion. The resizer processes the image in your browser and lets you download the resized version instantly.
Why use this tool?
Social media platforms, e-commerce sites, and email templates all require specific image dimensions. This free image resizer handles everything from profile photos to product images without Photoshop.
Frequently Asked Questions
What should I lock aspect ratio?
Locking the aspect ratio ensures that when you change width, the height adjusts proportionally (and vice versa), preventing distorted, stretched images.
What are standard social media image sizes?
Facebook post: 1200×628. Instagram square: 1080×1080. Instagram story: 1080×1920. Twitter post: 1600×900. LinkedIn banner: 1584×396. YouTube thumbnail: 1280×720.
Does resizing reduce image quality?
Reducing size (downscaling) preserves quality well. Increasing size beyond the original dimensions (upscaling) degrades quality as pixels are interpolated — the image becomes blurry. Avoid upscaling if possible.
Is this free?
Yes, completely free. Your images are processed locally with no server upload.
