TIFF FILE

[angelica_5702]

Hello,

1. Can someone enlighten me about the TIFF file? Can I use these kind of file for phone wallpapers? Is this an image or storage type only? 

2. Is it really different to have 72ppi image and 300ppi image? If the images would be used as phone wallpapers? 

Thanks,

Angelica

I don’t see how this is an Illustrator question, but I’ll give it a shot.

You don’t specify which phone, but it probably doesn’t matter. I bet the default Photo app on most phones supports TIFF images. As for resolution, PPI doesn’t matter here, only pixels matter. All images are just pixels. PPI matters when it is scaled and given physical . Your wallpaper will ignore the PPI value of the image and scale it to your screen.

Thank you. Apologies, I forgot this is not Illustrator related!

@angelica_5702 I would suggest using either JPEG or PNG file formats as a TIFF file will be considerably be larger files. JPEG probably be your best bet because for its compression keeping the file size suitable for most phone wallpapers. Problem with JPEGs is that it is lossy type meaning that the image does lose quality with excessive compression. You could also consider PNG which is a lossless type meaning no loss of information during the compression process. The file size may be a little bigger than JPEG but, PNG would be ideal for images with sharp edges or text.
