What is converting HTML to an image for?

Converting HTML to an image is the fastest way to turn a component, template or mockup into a ready-to-share PNG or JPEG, without relying on manual screenshots that crop poorly or lose sharpness.

Developers and designers use this tool to generate social media images, banners or previews from HTML and CSS code, keeping exact control over the final design at high resolution.

Converting HTML to PNG in the browser means your code never gets uploaded to an external server: all rendering happens locally, making it ideal for templates with client data or designs not yet published.

Frequently asked questions

Can I convert HTML to image for free with no limits?

Yes. FORMARTIO converts HTML to PNG or JPEG for free, with no sign-up and no watermark, directly in your browser. There's no limit on conversions.

What is the maximum resolution supported?

You can scale the image up to 4K. Keep in mind that 4x scale may not work with very large designs due to the browser's canvas limit (~4096px); in that case use 2x scale or the «Separate into individual images» mode.

Can I use my own CSS in the HTML?

Yes. You can include styles inside <style> tags and use @import for external fonts like Google Fonts. For security reasons, external <link rel="stylesheet"> tags are not supported.

Can I convert multiple slides at once?

Yes. If your HTML contains several elements marked with the .slide class, the tool automatically detects them, converts each one separately, and lets you download all the images together in a ZIP file.
