Frequently asked questions

How do I add text to an image online?

Drop an image in the upload area, type your caption in Overlay Text, and choose a Text Color, a Font Size in pixels (default 48) and a Text Position of Top, Center or Bottom. The Preview shows exactly what will be saved; click Download Image with Text to save the result.

What format is the downloaded image?

The image is saved at its original resolution with -text added to the file name. PNG sources stay PNG by default, keeping transparency, and JPEG sources default to JPEG at 92 percent quality. You can switch Output format between PNG and JPEG; with JPEG, transparent areas become white.

Why does 48 px text look small on my photo?

Font Size is measured in pixels of the original image. The preview is the same full-resolution canvas as the download, scaled to fit the page, so it matches the saved file exactly. On a photo 4000 pixels wide, 48 px text is small; the image size shown under the preview helps you choose a larger Font Size.

Can I change the font or add multiple lines of text?

The text is drawn in bold sans-serif, centered horizontally, with a soft drop shadow for readability; the font family cannot be changed. Only one line is supported and long text is not wrapped, so keep captions short or reduce the font size.

Can I use it to add a watermark to an image?

Yes, for a simple text watermark: enter your name or website, choose a color and set Text Position to Bottom. The text is fully opaque and centered; custom opacity, rotation and logo watermarks are not supported.

Are my photos uploaded to a server?

No. The text is drawn on an HTML canvas in your browser and the file is downloaded directly, so your image never leaves your device.
