Video & Photo Problems From iPhone

The file type might just be the way that the particular image is saved. As for the angle, I have no clue. XNViewMP has a batch convert feature but I haven't tried it. XnView MP | XnView.com

Take a look at a better image viewer than the Microsoft photos app.

I would suggest that you take a look at Irfanview which is totally free for personal use. It has a lot more functionality than the Windows 7 Photo App, and is easy to use.

I would not worry about converting between formats Both JPG and PNG, [Assuming that the PGN is a miss spelling ), are "lossy" Formats - to keep file sizes low for use on the internet they compress the original image and some quality is lost - so it is a compromise. The problem with this technique is that the compression takes place every time you save the file so that repeated saves will reduce the image quality. Due to this it is not recommended to convert and resave these types of image

The major difference between JPG and PNG files is that PNG supports transparency for use on the internet, [this allows the Round icons and other web page components you see on web pages ], whilst JPG does not support this transparency. The reason that you receive both types is I assume just a choice when they are shot.

The 90 degree turn can depend on how the phone was held when each shot was taken, there should be a code in the file that sets the viewing angle but apple has always set their own standard, ignoring those set by international agreement, which is one way to copyright their way and charge people extra for the "privilege" of using their hardware and software.

Irfanview has a default Slide type view which allows you to batch process changes such as rotation in addition to more in depth lighting and colour changes, it also has slideshow options which is useful for family images. It will display most popular image formats "out of the box" but also has an optional set of formats which is also free if you find you need them, apple are in the process of switching to a proprietary image format on their latest iPhones. so you may need a converter for these images should your Sone update their phone - I would expect Irfanview to have this where Photos is unlikely to

The only reason that I suggest that you retain the original format received is that the simple act of the conversion from PNG to JPG will lower the quality of the image due to the recompression of the image during each save.

I've since checked my original statement and PNG is primarily a lossless format, [you can use Lossy compression on a PNG file save to reduce the file size if you wish and your software supports it], so the PNG format would be a Better option for long term storage than JPG. PNG is a more modern international standard for images than JPG and was designed to cure some existing issues with JPG.

If you decide to convert PNG images to JPG, to minimise the loss of quality set your conversion to a quality setting of 100% or as close as you can to this in your software

There is a way to see what I am saying about JPG ... take a JPG file open it in an editor and resave as a new name - repeat this several times and you will see the lower quality of the last image compared to the original,

Of course it's a personal choice which format you use for long term storage, hopefully this explanation will help you get the best from your photos

Ok no promises

Have a read of this post https://www.makeuseof.com/tag/how-to...-media-player/ which may/should do what you want to do there are a couple of free solutions an app and a website to rotate video for Windows Media player but it should work in any player once rotated and saved, if not Windows media player is included in Win7 - Have not tried it, it's possible in windows 10 using the new included video editor

Edit

here's a link for the recommended Free software - Free Video Flip and Rotate: rotate video, flip video

I appreciate that download link. I was able to turn a video 90 Degrees and save it easily. I saved it as an AVI file and it wouldn't open with video, just audio! Then, I actually read the instructions that tell you to save it as an MP4 file and it worked great!! Who needs directions, right? Thank you very much!

I've just finished my own test and came back to pass on the same instruction I prefer MP4 anyway so would have defaulted to that anyway, i'm used to it as it's the default for my security camera recordings -- Glad to see you have a result
