iPad user-Export to camera roll?

I use my iPad air to edit and export my photos. If I export to camera roll does it save the quality of my image if my export settings are at 100% image quality? I noticed when saving the raw picture to my files the picture is 5.6 mb. Is it not recommended to export the file using an iPad? Thanks so much!

Yes it does preserve the image quality. What's the problem with the file-size being "only" 5.6mb? I assume you are exporting to Jpeg, yes? Jpeg is a lossy-compression format, meaning the image data from the original raw file will always be compressed, so a significant reduction in image size is always anticipated. Using 100% quality means use the least amout of compression, but generally speaking you should be able reduce the quality setting as low as 60-70% without any observable reduction in image quality.

Thank you! I am a newbie and I was watching a youtube video where they stated the image should be 9-10 mb. I am happy to hear I can continue to use my iPad to export files. Thanks again.

The size of the resulting file will depend on the size of the image, then the quality setting, and then the actual image content. That last item is because compression will be a lot more efficient on areas of similarity (e.g. lots of blue sky) and less efficient on areas of fine detail. Those differencies can have significant impact of the resulting file size.
