If you want your Mac's photos to wirelessly sync to all your other iOS devices and computers, you want to set up iCloud Photo Library: Apple's photo sync service lets you back up your images on all your devices, as well as access them — online or offline — on said devices. If you're willing to pay for the extra iCloud storage space, you can store an incredible amount of photos and videos, all accessible at the touch of a button or multi-touch screen.

2020-1-18  My iPhoto libary is 58 Gigs. They are all snapshots, nothing professional. Most of the photos were taken at 12megapixels because that's the default setting on the camera. I'm sure they will all look fine if they were reduced to 5megapixels. Is there a way in iPhoto to reduce the size of all photos in the Library to smaller? You can export photos in the original file format in which they were imported into your Photos library. A Live Photo is exported as two separate files: a still image file and a video file. In the Photos app on your Mac, select the photos you want to export. Choose File Export Export Unmodified Original.

Here's how to set it up on your Mac and get everything configured to your liking!

How to set up iCloud Photo Library on your Mac

How to optimize your photo and video storage

If you routinely shoot 4K video or high-quality images on your iPhone, iPad, or DSLR, you may run out of storage space fast. (I have a 1TB iMac, but also have almost a terabyte of 4K video stored in iCloud — it gets unwieldy, fast!) This is especially true if you have a Mac laptop with limited hard drive space: It's nice to look at your iPhone's gorgeous Portrait mode photos, but not necessarily always practical to store all of them locally.

Thankfully, Apple offers an Optimize Storage option, which lets you store full-resolution photos and videos of only your most recently shot and accessed imagery; all older photos and videos are available to download via iCloud and are stored as low-resolution previews on your device to save space. You can switch between optimizing your Mac's photos storage or storing your full library locally: Here's how!

Note: If you plan on using Optimize Storage, we suggest having at least one device that stores your entire library locally (usually a Mac with a large local or external hard drive), so you have multiple backups of your photographs and video.

1. Launch the Photos app on your Mac.
2. Click Photos in the App menu in the upper left corner of your screen.

3. Select Preferences from the drop-down menu.

How to share photos with iCloud Photo Library

Apple's photo service doesn't just provide online backups and sync for your images and video: The company also offers a free sharing service that allows you to send shared albums to friends and family (or create a publicly-shared website). Here's how to turn it on for your Mac.

iPhone have the best quality cameras, the latest iPhone – iPhone 7+ shoots pictures at 12MPx and videos at 4K resolutions. This means each photo size on iPhone 7 will be between 3MB to 5MB depending on colors. However, the built-in camera app does not offer any capabilities for you to reduce the size of these images.

If you own a 32GB or even 16GB iPhone, iPhone storage would be your most precious aspect and you would try hard even to save 1MB. You may not want to delete all the photos in iPhone as well. That’s why we need to compress iPhone photos.

4 Ways to Compress iPhone Photos

• 1. Compress iPhone Photos by Taking Screenshots of Photos
• 2. Compress Photos iPhone through Emails
• 3. Compress iMages iPhone with Help of iCloud
• 4. Compress iPhone Photos with iPhone Photo Compressor - Most Efficient

1. Compress iPhone Photos by Taking Screenshots of Photos

Okay, hands up, this seems crude, but it works, and that all that matters. The only downside to this is that it takes time to take a screenshot of all your photos. A great tip is to start early before your pictures are much.

1. Go to Photos app on your iPhone.
2. Scroll to the image you want to compress.
3. Tap the Home button and Sleep/Wake button at the same time.
4. The screen will flash to alert you that a screenshot has been taken.

You can edit the screenshots through Photos app, and delete the original photos from iPhone. The screenshot will take much less space than the original images.

2. Compress Photos iPhone through Emails

When you’re about to send photos via emails, iOS prompts you to choose a size for the image or to keep the actual size. You can choose the from Small, Medium, Large and Actual Size options. You can choose the medium one to ensure the picture quality is not affected too much. This is a rather easy way to compress iPhone photos.

You can send the compressed photos to your email. Download them to your Photos app and delete the original photos from iPhone.

3. Compress iMages iPhone with Help of iCloud

Maybe Apple's built-in solution is probably the simplest one. It can store all your photos from iPhone to iCloud online and keep the optimized images on iPhone. Once you select a photo to open it, it will be downloaded from iCloud. The app manages what's stored locally and what's on the cloud on its own, but the premise? Is that? You are on a fast enough connection.

To turn this on, go to iPhone/iPad Settings > Photos & Camera. Now turn on 'iCloud Photo Library' and select 'Optimize iPhone Storage.'
