Get the preview PDF

Compare preview to original

Infix will ask if you want to compare the preview to the original. You can compare each side-by-by or one above the other - choose whichever best fits the shape of the document. Or you can just open the preview on its own - Normal view.

Scroll, zoom-in, annotate your preview

As you navigate around the preview, the original moves in lock-step, making it easy to compare the two even when zoomed-in.

Though your preview is read-only, you can still add comments and annotations for others to read.

Download the final, editable PDF

After finishing the translation work in your CAT tool, you'll want to start editing the PDF and for that you'll need more than a preview.

Import your finished XLIFF as before but say 'No' when Infix asks if you want to open the preview. Instead choose Translate->Buy Final... from the menu bar.

Infix 7 license holders don't pay anything for the 'final' PDF and can download it as many times as they want.

If you don't have an Infix 7 license, you'll need to purchase credits in order to download the final PDF. You can then edit it in Infix free of charge for evermore - you don't need to buy an Infix license!
