You download a photo from your Facebook account, open it in Photoshop, and it looks completely wrong – purple tints, yellow casts, washed-out greys. Lightroom refuses to import it. Yet the same file looks perfectly fine in Mac’s Preview app. This is a common frustration for photographers, content creators and communication professionals. Here’s exactly what’s happening and how to fix it in under a minute.
Why Facebook Breaks Your Photo Colors
Every time you upload a photo to Facebook, the platform recompresses it. Regardless of the original format or quality, Facebook applies its own JPEG encoding to reduce file sizes on its servers.
The issue: during this process, Facebook sometimes embeds a preview thumbnail (called an EXIF thumbnail) inside the file. This thumbnail is encoded differently from the actual pixel data of the image. When you download the photo back, you get a file with an inconsistent internal structure.
The result: Photoshop reads the wrong source. Instead of displaying the real image data, it interprets the corrupted EXIF thumbnail – which explains the characteristic purple and yellow casts, and the strange pixelation even on supposedly high-resolution photos.
Why Changing the Color Profile Doesn’t Help
The natural reflex is to go into Photoshop, open Edit, and attempt a profile conversion to sRGB. It doesn’t work, for a simple reason: the problem isn’t the color profile. The file is already tagged as sRGB in its metadata. The issue is which layer of the file Photoshop is reading.
Changing the profile changes the label, not the source. You’re correcting the tag without touching the actual content.
The Fix: Using sips on Mac
On macOS, a built-in tool solves this instantly with no installation required: sips (Scriptable Image Processing System). It ships with every Mac.
sips forces Photoshop to re-read the actual pixel data of the file, bypassing the problematic EXIF thumbnail. It rewrites a clean JPEG from the correct data source.
Open Terminal (Cmd + Space, type Terminal) and run:
sips -s format jpeg /path/to/your-photo.jpg --out /path/to/fixed-photo.jpgThe fixed photo opens normally in Photoshop with its real colors.
Batch Processing an Entire Folder
If you have multiple photos to fix, there’s no need to process them one by one. This command processes all JPEG files in a folder and saves the corrected versions with a prefix:
cd /path/to/your/folder
for f in *.jpg; do sips -s format jpeg "$f" --out "fixed_$f"; done
echo "Done"All corrected photos appear with the fixed_ prefix in the same folder. Your originals are untouched.
Why This Happens Mostly With Facebook
Other platforms also recompress images – Instagram, WhatsApp, WeTransfer under certain settings. But Facebook is particularly problematic because its encoding frequently generates this inconsistency between the EXIF thumbnail and the actual pixel data.
Best practice going forward: never use Facebook as a source for recovering professional photos. Always keep your originals stored locally or in a dedicated cloud storage solution. Facebook is a distribution platform, not an archive.

Conclusion
The wrong colors in Facebook photos come from a corrupted EXIF thumbnail that Photoshop reads instead of the real image data. Changing the color profile does nothing. The fix is to use sips – a native macOS tool – to force correct file reading.
One command, thirty seconds, problem solved.
