[edit | edit source]
Convert SVG code to PNG image file
SVG to PNG Converter
[edit | edit source]This is a simple, one-page web application that allows you to convert Scalable Vector Graphics (SVG) code into a downloadable PNG image. You can either paste your SVG code directly into a text area or provide a URL to an SVG file. The app features a live preview and is built entirely in a single HTML file with no external dependencies.
Issues
[edit | edit source]- CORS - feathing svg image via URL doesn't work due to CORS policy.
Demo
[edit | edit source]Features
[edit | edit source]- Live Preview:
See a real-time rendering of your SVG code as you type or after loading it from a URLCORS issue - Paste SVG Code: Directly paste your SVG markup into the text area.
- Load from URL:
Fetch and display an SVG from a given URLCORS issue - Download as PNG: Convert the SVG to a PNG and download it to your computer with a single click.
How It Works
[edit | edit source]The magic of this converter happens in the browser, all thanks to a few powerful Web APIs. When you click the "Convert & Download as PNG" button:
SVG to Image: The SVG code is read from the input field. It's then used to create a JavaScript Blob, which is then used as the source for an Image object. This effectively treats your SVG code as a complete image.
- Image to Canvas: The app uses a hidden
<canvas>element. Once theImageobject has fully loaded the SVG data, it is drawn onto this canvas. - Canvas to PNG: The
canvas.toDataURL('image/png')method is called. This is the key step that takes the content of the canvas and encodes it as a PNG image in a Base64-encoded string. - Download: A temporary
<a>link element is created programmatically. The PNG data URL is set as the link'shrefand thedownloadattribute is set to a filename (e.g.,ds-image.png). Finally, the link is "clicked" to trigger the download, and then it's removed from the page.
Customization
[edit | edit source]This single-file application is very easy to modify. Here are a few ways you can customize it:
- Change the Styles: All of the CSS is located in the
<style>tag in the<head>. You can easily change colors, fonts, spacing, and layout directly in this section. - Change the Default Size: The default canvas dimensions are set to
500x500pixels in the JavaScript. You can modify these values in thedownloadButton.addEventListenerfunction by changing`500`. - Change the Filename: The default filename for the downloaded image is
svg-image.png. You can change this on line 200 + or so by editing thelink.downloadproperty.
- Use a Different Image Format: You can easily change the output format by modifying the
toDataURL()method. For example, to save as a JPEG, you can changecanvas.toDataURL('image/png')tocanvas.toDataURL('image/jpeg').
