Paste your <canvas> tag below, specify the attributes to remove, and click Remove.
How to Use This Tool?
Step 1: Open the Tool Save the HTML code as a file (e.g., canvas-remover.html) and double-click it to open in any browser. No installation or internet needed — it runs entirely offline.
Step 2: Paste Your HTML In the "Input HTML" box, paste the HTML containing <canvas> tags you want to clean.
For example:
<canvas id="myCanvas" class="chart" style="border:1px solid #ccc" width="400" height="300">
Your browser does not support canvas.
</canvas>
Step 3: Set Attributes to Remove In the "Attributes to remove" field, type the attribute names separated by commas. The default is class, id, style.
→To remove only class and style, type: class, style
→To remove ALL attributes, type: * (asterisk)
Step 4: Set Preserve List (Important for Canvas) In the "Preserve (don not remove)" field, list attributes you want to keep. The default is width, height. This is critical — if you remove width and height, the canvas resets to its default 300×150 buffer, which can break your drawing or make output blurry. Recommended preserve list: width, height, role, aria-label
Step 5: Click "Remove Attributes" Press the ⚡ Remove Attributes button. The cleaned HTML appears in the "Output HTML" box, and a green success message shows below it. Input:
<canvas id="myCanvas" class="chart" style="border:1px solid #ccc" width="400" height="300">
Output:
<canvas width="400" height="300">
Step 6: Copy the Result Click the Copy button at the top-right of the output box. It turns green and shows "Copied!" — the cleaned code is now in your clipboard.
Step 7: Reset (If Needed) Click ✕ Clear to empty all fields and start over.
Important: The <canvas> tag has fallback content between its opening and closing tags. The tool only removes attributes — it never touches the fallback text, so your content stays exactly as it was.
