In Intento we have a lightweight web application allowing you to upload different formats of files and translate them via multiple MT engines in a blink of an eye — MT Portal.
It supports plain text, HTML, XML or MXLIFF (Memsouce specific format), should you require additional formats support, please let us know via hello@inten.to.
Also, we work with all the formats supported by MS Office and such CAT Tools and TMS integrations as MemoQ, Trados and MateCAT. Please note that different engines might have specific restrictions for certain formats.
