A powerful browser-based tool for artists to overlay reference lines and prepare images for printing.
This webpage allows you to upload a picture, preview it in standard paper formats (like A4, A3, etc.), add various grid and line overlays, and download a high-resolution, print-ready copy for use as a drawing or painting reference.
- Modern UI: A clean, responsive, card-based layout that guides the user through the workflow.
- Print Format Previews: Choose from standard paper sizes (A5, A4, A3, A2, A1) to see how your image will fit.
- Orientation Control: Select Portrait or Landscape orientation. The tool intelligently suggests a default based on your image's shape.
- High-Resolution Export: Downloads a 300 DPI PNG file, perfect for high-quality printing.
- Multiple Line Overlays: Add simple grids, diagonals, and complex diamond patterns.
- Custom CM Grid: Create a grid with line spacing defined in centimeters, based on the image's physical dimensions.
- Dynamic Filenames: Downloaded files are automatically named with their format and settings (e.g.,
image-A4-portrait-2cm_grid.png).
- Select a file: Upload your source image.
- Choose an Output Format:
- Use the dropdown menu to select a paper size (e.g., A4). The preview will show how your image fits in that aspect ratio.
- If the format is not "Original", orientation controls (Portrait/Landscape) will appear, allowing you to choose how the image is framed.
- Add Reference Lines:
- Click the image buttons to add pre-defined grids or diamond patterns.
- To add a custom grid, enter a value in centimeters into the "Grid spacing (cm)" field and click "Apply Grid".
- Download Your Image:
- Click the "Download Image" button.
- The tool will generate a high-resolution 300 DPI file in the background and start the download. If the process is slow, the button will display "Generating..." to provide feedback.
