Frequently asked questions
Does Tervix store my files?
No. Files are processed inside the browser and disappear when the page closes or reloads.
Is there a size limit?
Tervix imposes no fixed limit, but large files can exceed available device memory.
Does compression always make files smaller?
No. Already-compressed files, images and some PDFs can remain similar or grow; compare before saving.
