Image Configuration Tool

Apply recommended specifications for optimal image display and performance.

How to Use
  • Upload Your Image: Click the "Upload your image:" field and select an image file (PNG, JPG, JPEG). The original image will be displayed on the canvas, and its type will be shown.
  • Set Dimensions & Aspect Ratio:
    • Enter desired **Width** and **Height** in pixels.
    • Use the "Maintain Aspect Ratio" checkbox to automatically adjust one dimension when the other changes, preserving the image's original proportions.
    • Quickly apply recommended dimensions using the "Optimal (1280x640)" or "Minimum (640x320)" preset buttons. These presets automatically set a 2:1 aspect ratio.
  • Set Safe Margin: Enter a value in pixels for the "Safe Margin". A transparent red rectangle will appear on the canvas, showing the area within the margin. This is a visual guide to ensure important elements aren't cut off by UI elements on different platforms.
  • Choose Output Format: Select your desired output format (PNG or JPG/JPEG) from the dropdown. The "Output File Type" in the info section will update to reflect your choice. If "Original Format" is selected, the tool will attempt to use the original image's format, defaulting to PNG if the original format is not supported for web output.
  • Set JPG Quality (if applicable): If JPG/JPEG is selected as the output format, an additional slider will appear to let you control the compression quality (1-100).
  • Set Resolution (DPI): Enter your target DPI. **Note:** This is for informational purposes only and does not change the pixel dimensions of the image or directly embed DPI metadata in the output file via the browser's `toDataURL` method. Web images are primarily concerned with pixel dimensions.
  • Color Mode: This tool outputs images in **RGB** color mode, which is the universal standard for web display. This field is for display only.
  • Apply Changes: Click the "Apply Configuration" button. The image will be resized and displayed according to your settings. The "Estimated Output Size" will update, and a warning will appear if it exceeds 1MB (a common safe limit for web platforms).
  • Set Download File Name (Optional): Enter a custom name for your file in the input field. If left blank, the file will be named `configured_image.png` (or `.jpg` based on your chosen output format).
  • Download Image: Click "Download Configured Image" to save the file.
  • Reset: Click the "Reset" button to revert to the original uploaded image and default configuration settings.
