No more resizing a photo five times to get under 50 KB, or finding out at the last minute that the upload was rejected.
Search for an exam, passport, visa or job form. Aptafix lists every file it asks for, with the exact size, a link to the official notice and the date we last checked it.
Take or choose a photo. Aptafix frames your face, turns a plain wall white, cleans up your signature and hits the exact pixels and KB.
