Resize Image Tutorial

The **Resize Image** tool allows you to easily adjust the dimensions of your photos for social media, email, or web use. Our tool works entirely in your browser using HTML5 Canvas, ensuring privacy and speed.

1. Upload Your Image

Start by uploading the image you want to resize. We support various image formats including JPG, PNG, and WebP.

Upload Options:

  • Select Image: Click the blue "Select Image" button to open your file browser.
  • Drag & Drop: Drag your image file directly into the designated upload area.

Once uploaded, the tool will display the original dimensions of your image.

2. Select Resizing Method

You can resize your image using three primary methods:

Method A: By Pixels (Width & Height)

  • Enter the desired **Width** in pixels (e.g., 800).
  • Enter the desired **Height** in pixels (e.g., 600).
  • Maintain Aspect Ratio: Keep the icon locked (default) to automatically calculate the height/width, preventing distortion. Unlock it to enter custom dimensions (may stretch the image).

Method B: By Percentage

  • Use the **Percentage** field to scale the image up or down relative to its original size.
  • Enter **50%** to halve both the width and height.
  • Enter **200%** to double both the width and height.

Method C: Using Presets

  • The tool provides common presets for popular platforms (e.g., Facebook cover, Twitter header).
  • Selecting a preset instantly applies the standard, recommended pixel dimensions.

3. Process and Download

After setting your desired dimensions, the resizing process is instant and efficient.

Steps to Finalize:

  • Click the blue **"Resize Image"** button. The tool will process the image on the client side.
  • A **"Download"** button will appear. Click it to save your newly resized image.
  • The output format is typically the same as the input, but PNG is often used for quality.

To try different sizes, simply change the values in the input fields and click "Resize Image" again.
