The Google Translate application now supports in-image OCR and translation of text:

but this functionality does not seem to be accessible using a PC and visiting translate.google.com.
How can I get it to work for files on my PC (with no Android phone)?
Note: People somehow assume I have Google Drive, or a Google Account etc. I never said that.

Not Google, but similar.
Yandex Translate has image upload using desktop web browsers.

I use this in a Flotato browser which enables me to quickly translate screen grabs without them accumulating on my hard drive (because the screen grab is automatically deleted after I've dragged it onto the Yandex/Flotato window).
