About compressing digital images for storage

[Stephen Liu]

Hi all

I'm going to scan about 1,000 photos to digital images.  On testing I found the size of each digital image is about 2.0MB.  

I can compress its size to about half, 1.1MB on GIMP;
File -> Export As -> Select File Type (By Extension)
file type - jpg
-> Export
Export Image as JPEG
Quality --> 85

The final compressed size of the digital image = 1.1MB

Would the compressed image files affect their future use?  I won't print them but use them on digital album, digital slideshow, posting on websites etc.

Please advice.

Besides I'll further compress and archive all digital files running "gzip"

Thanks

Regards
