Google Photos has long offered one of the best deals in all of photo storage: itāll back up your entire library for free, so long as it can compress the images a bit. But as of tomorrow, June 1st, that deal goes away, and youāre now eating through Google storage (which you may have to pay for) whether your images are compressed or not.
With the change looming, Iāve been wondering how bad Googleās compression actually is. Does the compression leave my photos in āHigh Quality,ā as Google has claimed for years? Or does the compression degrade my photos enough to make it worth using more storage by switching over to āOriginal Qualityā backups?
I ran some quick tests this morning to find out. I took some photos and videos from my Pixel 5 (one of a few phones that will continue to get free compressed storage) and a photo from my Fuji X-T30 and uploaded them to two separate Google Photos accounts, one with compression turned on and one that maintained original quality.
The results were mixed. For photos, the compressed versions were often indistinguishable from their uncompressed counterparts. But once youāre losing resolution, the compression really starts to show.
Hereās what I found across a handful of tests. You can click the images to view them at a larger size.
I canāt find a difference in this photo of my cat
Hereās a photo I took recently of my cat, Pretzel. I zoomed in on his hair, his eyes, and the books in the background, and I canāt find a difference. The photo, taken on a Pixel 5, was originally 3.4MB but was compressed down to 1.5MB.
This ultrawide photo looks basically the same
I took this picture on Yaleās campus last weekend with the Pixel 5ās ultrawide camera. Both versions look great while in full screen on my computer. You could probably make an argument about whether thereās some more noises around the edges of the leaves in the compressed version, but Iām generally of the mindset that if you have to search for image issues, they donāt really matter.
The space saving isnāt very substantial here: Googleās compression takes the file size from 7.3MB to 5.7MB.
The image size shrinks dramatically from my mirrorless camera
Hereās a photo I took this morning of Pretzel on my Fuji X-T30. I zoomed in on his face, and couldnāt find a difference even when both were blown up as large as Google Photos could make them.
At first, it seemed like this was a situation where Google Photosā compression won out: the file size shrank from 12MB to just 662KB, and the images look practically identical.
But thereās one very notable difference. Google caps photo resolution at 16 megapixels, which shrank the photo significantly from the original 26 megapixel file my camera saved. Hereās a zoomed-in crop showing how the detail starts to disappear as blocky noise comes in:
Now look, I donāt know that I need all 26 megapixels of this image at this point in time. But if I ever wanted to print this photo in a larger format, crop it down the road, or otherwise make changes to it, those extra pixels would be a huge advantage to have retained.
Video compression is just bad
Thereās nothing inherently wrong with 1080p video, but there is something wrong with the way Google processes it. And unfortunately, if you use Googleās compression, all your videos will be compressed at 1080p.
When that happens, everything becomes smudgy, details just vanish, and some colors even lose their pop. Itās a really significant downgrade in terms of quality. Iām not able to embed a Google Photos video here, so I included a screenshot comparison above. I think you can see most of the differences, although itās much clearer how blurry text becomes at larger sizes.
I originally recorded this video in 4K back on my Pixel 5 back in February. It looks nice enough on my not-4K computer screen. Street signs, faces, and the falling snow all look sharp. But the compressed version is kind of a mess ā it looks like I recorded it with a layer of grease on my camera lens.
The loss (or savings) of data is a big one here: it falls from 55MB for this 10 second clip to just 6MB. No wonder it looks so much worse.
The compression makes a difference… sometimes
I still came away mostly impressed by the quality maintained after Googleās compression. For photos, the result can be nearly indistinguishable so long as the original file is under 16 megapixels. But for videos, thereās no question that uncompressed is the way to go. Itās too bad that Google doesnāt let you set different options for photos and videos.
The real drawback is that compressing your photos doesnāt always save a ton of space. That extra space definitely adds up as you push thousands of new photos into the cloud each year. But if youāre going to have to pay anyway, it might be worth maintaining your photos ā and especially your videos ā at their full quality, especially if youāre uploading them in higher resolutions.
