need to change aspect ratio

I don't have many friends who would know about this so I've had to ask here.

Looking back on all my travel photos pre 2015, I realise that nearly every photo I've taken is in the 4:3 format, which I hear is obviously the standard aspect ratio and also renders the highest quality. However, I would like to now change some of these photos to 16:9 landscape format if possible.

Does anyone know of a program online perhaps or otherwise where I can change the aspect ration of these photos from 4:3 to 16:9 and without the image quality being distorted? I know photoshop is capable of this, however, I'm not spending almost £100 and have never used it before. Surely there must be somewhere online where I can do this? I found one called iResizer but when it formats to 16:9 the whole image itself becomes stretched and distorted.
 
A 4:3 format in itself has no inherent quality adventage, except that in your case it's possible that you have a certain digital camera and that format uses the whole image sensor of that camera.

Of course re-sizing is going to stretch the image! What didi you expect?

All you can do to change the proportions, is to crop the picture - thereby losing a good measure of the content. But what's left won't be distorted.
 
And you can crop in virtually any program, certainly if you have Windows or a Mac or a smartphone you can do it easily.

Click to expand...

Not necessarily the 'Standard'. Let's face it 35mm was the standard for many decades (and still is to a certain extent) that is 36mm x 24mm which renders it 3:2. As droj states, doesn't imply inherent IQ.
 
I may be wrong, but surely to change from a 4:3 format to 16:9, has to involve cropping the image, if you wish to avoid distortion by using transitions. Also I don't follow how one format against another "renders the highest quality". I,m curious to know why you wish to try and change the old images?
 
Changing from 4:3 to 16:9 does require cropping, which you could do. But that would cause you to loose some image. You could do what you see a lot of now with smart phone video's is to pad the extra part of the image. Probably the simplest way, provided you dont have too many images is to take the image you want to "expand" Copy it and then crop to the 16:9 ratio. Next blur the image so that it forms a nice diffuse background ( probably Gaussian blur would do the trick) then drop the original image back on top.
 
16:9 works ell for landscapes etc (not all). Many photos would work at that format.

Kinda depends on what you want to show. Some portraits work well at 9:16 (portrait format rather than landscape format.)

As said, most photo development programmes allow you to change the format, of course you might loose a bit of the original if that was not of the same format.

Play with it.........

To avoid cropping set the canvas in Photoshop to a 16:9 format , the size must me bigger then the original image size.
Then free transform the image to fit into the canvas. That's in Photoshop.
This will leave a while edge but keep the image ratio correct
I hope this helps

Granted it is only 1 day since this new member posted, so still early.

But IMO until he returns and acknowledges that he understands that it is not possible to simply expand a 4:3 ratio image to a 16:9 ratio without distortion (or tries something like @Retune suggestion in post #8) and poses any next question(s) about what can be done...........all else now is repetition and speculation ;)
