Is there any AppInventor extension to convert JPG file to PNG?

[Raoulian]

Hello.

My son is making his app using AppInventor for homework. We want to make an OCR translator - when you take a picture of the text, then the app automatically recognizes the text in the picture and translates it to another language.

We find a cool OCR extension made by Mika that has the method to get the picture of the text and return a string of the text. But Mika's extension requires a PNG image, while the Android photo app uses JPG.

So I try to find some extension to convert JPG to PNG, but I failed.

Does anyone help to find the converter, or recommend another OCR extension that can use JPG file as an input?

Change the file name ending from (.jpg) to (.png).

[Free] Extension to convert image format jpg / png / webp

[Image] com.kumaraswamy.convertor.aix (6.9 KB) Just enter the image you want to convert with the new image path. The image will be accordingly encoded to the mime/file type (JPG, PNG, WEBP) of the output path See post 14 for extension update See post 15 for second update to extension, which includes a resize function
