About Image Resizing
Image resizing changes the pixel dimensions of an image. Whether you need to scale down a 4000×3000 photo for a blog post or upscale an icon, this tool handles it all in your browser.
Maintaining the aspect ratio is important to avoid stretching or squishing your image. When you lock the ratio, changing one dimension automatically calculates the other. This ensures your photos look natural at any size.
Common resize targets include 1920×1080 for Full HD displays, 1200×630 for social media Open Graph images, 800×600 for blog posts, and 150×150 for profile thumbnails.

Frequently Asked Questions
Does resizing reduce image quality?
Downscaling (making smaller) preserves quality well. Upscaling (making larger) can cause blurriness because new pixels must be interpolated. For best results, start with the largest version of your image.
What is aspect ratio and why does it matter?
Aspect ratio is the proportional relationship between width and height (e.g., 16:9, 4:3). Maintaining it prevents your image from looking stretched or squished when resized.
What are common image sizes for social media?
Facebook/LinkedIn OG: 1200×630, Instagram post: 1080×1080, Twitter post: 1200×675, Pinterest pin: 1000×1500, YouTube thumbnail: 1280×720.
Can I resize images without losing quality?
When downsizing, quality loss is minimal. The tool uses browser-native Canvas resampling which produces sharp results. For lossless output, choose PNG format.
Is there a maximum image size I can resize?
There is no server-imposed limit. The maximum depends on your device's memory and browser capabilities. Most modern devices handle images up to 8000×8000 pixels.
