About the Image Resizer

The Image Resizer lets you change the width and height of your photos and graphics directly in your browser. It is designed for everyday tasks such as preparing images for website banners, social media posts, ecommerce product listings, documents, and profile avatars.

All image resizing happens 100% locally on your device using your browser's canvas engine. Your files are never uploaded to any remote server or stored in the cloud, ensuring complete privacy and fast processing.

How to Resize an Image Online

  1. Upload Your Image: Click to browse or drag and drop your JPG, PNG, or WebP file into the dropzone.
  2. Set Desired Dimensions: Enter your target width or height in pixels. Keep the "Keep aspect ratio" option enabled to maintain proportions without distortion.
  3. Resize & Download: Click "Image Resizer" to process the file instantly and download your resized image.

Key Tips for Resizing Images

Maintaining Aspect Ratio: Locking the aspect ratio ensures your image scales proportionally, preventing unwanted stretching or squeezing.

Downscaling vs. Enlarging: Reducing image dimensions (downscaling) creates smaller files and sharp visuals for web use. Enlarging images beyond their original pixel dimensions (upscaling) may introduce softness or pixelation because new pixels must be interpolated.

Format Compatibility: You can upload any standard web image format including JPG, JPEG, PNG, WebP, and GIF.

Image Resizer FAQs

How do I resize an image by pixels?

Upload your image, enter your target width or height in pixels, and click the Image Resizer button to download your resized image.

How can I resize an image without stretching it?

Keep the Keep aspect ratio switch enabled. When aspect ratio is locked, entering a new width automatically calculates the matching height proportionally so your image never distorts.

Does reducing image dimensions lower the file size?

Yes. Decreasing the pixel dimensions reduces the total pixel count, which typically lowers the file size, helping web pages load faster.

Which image formats are supported by this resizer?

The resizer supports standard web image formats including JPG, JPEG, PNG, WebP, and GIF.

Are uploaded images sent to a server?

No. All processing runs 100% locally in your web browser using HTML5 Canvas. Your images are never transmitted or stored on any server.
