What HTML to Image helps you do

Render self-contained HTML markup into a custom-size PNG image in your browser. It is useful for turning a styled card, chart or table into a graphic without a screenshot. Scripts, iframes, embedded objects and remote assets are stripped before rendering, so the output is built only from the markup and styles you paste.

Rendering happens in your browser. Haivix does not receive your markup or the rendered image.

How it works

These tools decode the image in your browser, draw it onto a canvas, apply the change, and encode a new file. Nothing is uploaded, so the result depends on the browser's own decoders and encoders rather than a server library. Re-encoding always creates a new file: metadata such as EXIF, GPS and color profiles is generally dropped, and JPEG or WebP output loses a little quality on every save. Canvas work is capped at roughly 36 megapixels, so very large images may be refused rather than processed slowly. Browsers normally apply EXIF orientation when decoding, so a phone photo usually appears upright before any rotation is applied.

How to use HTML to Image

Paste self-contained HTML with inline or embedded styles.
Set the output dimensions and background color.
Render the markup and inspect the preview.
Download the PNG.

When to use it

Turn a styled card or table into a shareable image.
Export an HTML mockup as a PNG for a document.
Produce an image from markup without a design tool.
Render a social card from a template.
Turn a simple chart made of divs into a PNG.
Create a consistent image from a reusable snippet.

When not to use it

Do not use it to capture a live URL; only pasted markup is rendered.
Do not rely on external images, web fonts or scripts.
Do not expect browser-perfect rendering of complex layout features.

Example

A self-contained HTML card with inline styles renders into a PNG at the width and height you set. A remote image referenced by URL is removed before rendering, so it appears blank. A web font that is not available locally falls back to a system font, which can change line breaks.

What you can do with HTML to Image

Paste HTML markup and render it to canvas.
Set the output width and height up to 5000 pixels.
Choose the background color.
Remove scripts and remote assets for safety.
Preview the rendered PNG.
Download the image locally.

Example: pick the format for the job, then check the result

Keep the original. Every tool downloads a new file, and repeated conversion between lossy formats compounds artifacts.

Choose the format by purpose: PNG for sharp edges, text and transparency; JPEG for photographs; WebP when file size matters on the web.

Check transparency before converting to JPEG. Alpha is flattened onto a background color, and the choice is permanent in the output.

Look at the output at 100 percent. Smoothing, sharpening and watermark placement are easier to judge at full size than in a small preview.

For a batch, check the ZIP contents and file count. A single failed image is reported separately and does not stop the rest.

Note the output dimensions and file size. A larger pixel count does not always mean a better result, and a large PNG can be slower to load than a smaller JPEG.

What to know before you start

It renders the markup you paste and cannot capture an arbitrary public webpage URL.
External fonts and images may not load, and cross-origin assets can be blocked from the canvas.
Scripts and iframes are removed before rendering, so interactive content is not captured.
The output is a raster PNG, not vector or selectable text.

Common mistakes

Expecting an external image or font to load.
Pasting a full page with scripts, which are stripped.
Setting a canvas smaller than the content and clipping it.
Assuming the output has selectable text; it is a raster PNG.

Troubleshooting

If the render is blank, the markup may depend on scripts or remote assets that were removed.

If content is cut off, the canvas is smaller than the content or the overflow is hidden.

If fonts differ, the requested face is not installed on the device.

If a color looks off, check for a background color that was not set.
