FAQs: how to make a photo less mb on iPhone

Will reducing the photo file size lower image quality?

Compression does comprise reducing the quality. But it's worth mentioning that if you switch to taking photos in Apple's HEIC mode, the quality remains, but the file size is less. But if you're then looking to compress an image, in general, you'll lose quality.
