Android photos transferring to Mac in low quality: why it happens and how to fix it
If your Android photos look worse on your Mac than on the phone, the photo was almost certainly shrunk on the way there, and the route is what shrank it. The two documented culprits are Google Photos backup set to Storage saver or Express, and sending pictures to yourself through a messaging app. A third cause is not a loss at all: newer photo formats can look different in a Mac app that does not fully support them. The fix is to move the original file, by cable or with a local wireless tool, and to check one photo before trusting a method.

How do I tell whether the photo was really shrunk?
Compare numbers, not impressions. A phone screen is small and sharp, so the same file can look softer on a big display without anything being wrong.
- On the phone, open the photo in your gallery app and view its details. Note the pixel dimensions and the file size.
- On the Mac, select the file in Finder and press Command-I. Look at the file size and the dimensions.
- Compare.
| What you find | What it means |
|---|---|
| Same dimensions, same size | The file is the original. Look at the format section below |
| Smaller dimensions | Something resized it. Usually a backup quality setting or a messaging app |
| Same dimensions, much smaller size | Something re-compressed it |
Is Google Photos reducing my photos?
It does if the backup quality is set that way. Google's backup quality page describes three settings.
| Setting | What Google says happens to photos |
|---|---|
| Original quality | "Photos and videos are stored in the same resolution that you took them with no change to their quality" |
| Storage saver | "Photos and videos are stored at a slightly reduced quality." Photos larger than 16 MP are resized to 16 MP |
| Express | Photos larger than 3 MP are resized to 3 MP. Google notes it may not be available in all regions |
If your phone's camera shoots above those sizes and you back up in Storage saver or Express, then a download from photos.google.com gives the Mac the reduced copy. The website cannot give you back pixels that were never uploaded.
To check or change it, Google's steps for Android are:
- Open the Google Photos app.
- Tap your profile picture or initial.
- Tap Google Photos settings, then Backup, then Photos & videos quality.
- Choose Original quality.
Original quality uses more of your Google Account storage, which Google's backup page says is shared with Drive and Gmail. The original is still on the phone unless you deleted it, so for photos you already care about, copy them directly using one of the routes below.
Do messaging apps reduce photo quality?
Yes, and Google says so about its own. The help page for sending photos in Google Messages states: "Carriers compress MMS messages, which can impact image quality." For RCS chats, it describes a media quality button with two choices:
- HD, optimized for chat: "Sends quality media faster, uses less data."
- HD+, original quality: "Sends at full media resolution."
Google says the option you pick is saved and used for future images. So if you text photos to yourself and open them in Google Messages for web on the Mac, tap the HD button when attaching and choose HD+.
Other chat apps have their own quality settings. Look for a media quality or HD option in whichever app you use, and read its help page before you rely on it. As a rule, a chat app is the wrong pipe for a photo you intend to edit or print.
Email is a different case. Gmail's attachment page describes no resizing, only a 25 MB limit, above which the attachment becomes a Google Drive link. If your mail app offers a choice of image size when attaching, pick the largest.
Could it be the photo format and not the transfer?
Sometimes. Two formats cause confusion.
HEIC or HEIF. Android's list of supported media formats includes HEIF, with .heic and .heif files, from Android 8.0. Apple's page on HEIF and HEVC media is written about photos from an iPhone or iPad, and says macOS High Sierra 10.13 or later can view, edit, or duplicate HEIF media. So a .heic file from the phone is not a degraded photo. It is a different container, and a current Mac opens it. Trouble starts only when a website or an old app refuses the file and you convert it to something smaller to get it through.
Ultra HDR. Android's documentation for the Ultra HDR image format describes a JPEG file that carries an extra layer called a gain map. It explains what happens in software that does not understand the layer: "Legacy readers that don't support the new format read and display the conventional low dynamic range image from the image file." In other words, the photo can look brighter and punchier on the phone's HDR screen than in a Mac app that shows only the standard image. The file is the same size and resolution. We have not found an Apple page stating which Mac apps render Android's gain map, so compare by eye in more than one app before blaming the transfer.
If your numbers match and the picture still looks flatter, this is the likely reason.
Which routes copy the original file?
These move the file itself. None of their makers' pages describes resizing photos, and Google's Quick Share page mentions none either.
| Route | What it needs | Guide |
|---|---|---|
| USB cable with OpenMTP | A data cable and the free app on the Mac | USB file transfer |
| Quick Share to AirDrop | A phone on Google's supported list | AirDrop from Android to a Mac |
| LocalSend or NearDrop | Same Wi-Fi network; both free | Wi-Fi file transfer |
| The Relay | Same network; paid | See below |
| Google Drive upload | Internet and Google storage | Google Drive between Android and a Mac |
| Google Photos | Backup set to Original quality | Google Photos on a Mac |
One habit matters as much as the tool: share the photo from the phone's gallery or files app, not from inside a chat thread or a social app. A picture saved back out of a conversation is the copy that app kept, which may not be the original.
Where does The Relay fit?
The Relay gives you a window on the Mac that browses the phone's storage. You open the camera folder and drag the photo files to the Mac over your local network, so you are moving the files themselves, with no file-size limit set by the app. It also syncs the clipboard both ways, including images, which is handy for a screenshot you want to paste into a document. It costs $19.99, paid once, and needs Android 8.0 or later and macOS 13 Ventura or later.
It does not sync or back up a photo library; Google Photos at Original quality is the tool for that. If you move photos only now and then, a cable or LocalSend is free. If you edit your pictures, see getting phone photos to a Mac for editing.
Questions people ask
Why are my Android photos blurry when I send them to my Mac?
Because the route made them smaller. Google documents two cases: Google Photos backup in Storage saver or Express quality resizes large photos, and MMS messages are compressed by carriers. Move the original file by cable or a local wireless tool.
Does Google Photos reduce quality when I download to a Mac?
The download gives you what was backed up. If backup quality is Original quality, Google says photos are stored with no change. In Storage saver, photos above 16 MP were resized before they ever reached Google.
Can a Mac open HEIC photos from an Android phone?
Apple says macOS High Sierra 10.13 or later can view HEIF media. That page is written about iPhone and iPad photos. Android's documentation lists the same format, with the same .heic extension, from Android 8.0.
