Long text warning!
Today, I needed to upload a photo to a site that required a jpg file extension. As most of us know, Apple wants us to save everything image-related as png on our mobile devices, so this is the unchangeable default for most photo apps - at least the free ones, and that includes the likes of photoshop express. To add insult to injury, since Photos.app doesn’t show image EXIFs (metadata), it took me a while to figure out why my pic was being rejected.
Well, I downloaded a free (and ugly, locked in portrait, obviously directly ported from the iPhone) app called EXIF doctor and found out the issue, that is, all my photo editors were rendering a png file, not the required jpg. I downloaded another free (and equality ugly, locked in portrait, ported from iPhone) app called JPEG<->PNG and converted my file. Do you thing my problems ended at that point? Nooooo... the site I needed to upload my pic too was really picky, the pic had to be a jpg file, not a jpeg file (which I found out was the file extension using the ugly EXIF doctor again). Despite, as many of you know, jpg and jpeg being the very same thing.
So I thought, now iOS has a file manager! It’s just a matter of opening the said pic in Files.app and deleting the offending letter, since as I said, jpg and jpeg are the same file and it shouldn’t matter. Right? Wrong! The useless Files.app irrevocably hides all file extensions. I’m sorry for everyone that drank Apple’s Koolaid and bought an iPad as a MacBook Pro replacement. So, again after more moments of tedious research, I bumped into an app called Documents.app. It should be able to change file extensions and was free! So I download my third app for something that has been pretty straighforward on any other OS since, say, Windows3.11. Opened my pic there and voilà, it did have the option of changing the extension. So I did it and hapilly followed to upload my pic.
It was a trap! Documents.app just pretended to change the file extension, but saved my pic as picture.jpg.jpeg.
At this point, I remembered good old AudioShare. The app that since ages has the option to select or not to keep a file extension. Okay, so I browsed the pic, imported it to AudioShare and it reported the tricky hidden jpeg extension that eluded Documents.app. I simply deleted the .jpeg part.
IT WORKED! Problem solved. From now on, every time I need to change (or find out, btw) the extension of a file on iOS, I know where to do it.
Shame on you, Apple with the half-baked Files.app. Shame on you, developers of the ugly Documents.app that promise a feature that simply doesn’t work. Praise AudioShare and its developers!
