what's the best free tool to edit text in an image on iphone?

For editing text in images on an iPhone, Snapseed and EditTextImage are both great free options, each offering unique benefits. Snapseed is a versatile mobile app by Google that includes a 'text' tool for adding and editing text with various fonts and styles.

the tool, although designed primarily for web use, is also accessible from mobile browsers, making it possible to work directly from your iPhone. It specializes in replacing text while maintaining the image’s original aesthetics, thanks to its generative inpainting technology, which fills in the text area seamlessly.

Snapseed is more flexible for those who need broad editing features beyond text manipulation, such as filters and adjustments. However, it doesn't automatically match fonts to the original text in your images, which can be a drawback if consistency is critical.

Both tools are highly rated for their ease of use and extensive features, but the tool’s ability to automatically detect and replicate font styles makes it particularly strong for tasks where matching the original text style is crucial. For final output, using PNG can be beneficial to maintain quality and transparency in your modifications.
