Introduction
You upload a batch of JPG photos to Google Drive from your phone, and when you download them later on your computer, they have turned into HEIC files. Or you notice that photos backed up from your iPhone arrive in Google Drive as HEIC even though you wanted JPG. Google Drive and Google Photos interact with HEIC in ways that can surprise you, and the settings that control it are not obvious. In this guide we cover why Google Drive converts photos to HEIC and how to stop it so your files stay in the format you want.
Why This Happens
The HEIC conversion in Google Drive usually traces back to two sources. First, if you back up photos from an iPhone with HEIC camera mode enabled, Google Photos and Drive store the original HEIC files rather than converting them on upload. Second, Google Photos has a Storage Saver feature that re-encodes uploaded photos to save space, and in some cases this produces HEIC files. The result is that photos you thought were JPG end up as HEIC in your Drive, which causes problems when you download them to a Windows PC or try to share them with non-Apple users. Google does not make the format behavior obvious, so you have to dig into settings to control it.
3 Solutions
Solution 1: Convert HEIC files after downloading. Download your photos from Google Drive, then run them through the piczen HEIC to JPG converter in your browser. Quickest fix for existing files.
Solution 2: Switch iPhone to Most Compatible mode. Change Settings > Camera > Formats to Most Compatible so future photos save as JPG on the phone, and Drive backs up JPGs.
Solution 3: Disable Storage Saver in Google Photos. Open Google Photos settings and set backup quality to Original. This prevents re-encoding to HEIC during backup.
Step-by-Step Guide
To fix existing files, open your browser and navigate to Google Drive. Locate the HEIC photos you want to convert. Select them, right-click, and choose Download. Google Drive packages them into a zip file. Save the zip to your computer and extract it. Open a new tab and load the heic to jpg converter. Drag the extracted HEIC files onto the converter page. Pick JPG as the output and set quality to high. Click Convert and download the JPGs. To prevent future HEIC uploads, grab your iPhone, open Settings, tap Camera, tap Formats, and select Most Compatible. New photos will save as JPG. Then open the Google Photos app, tap your profile, tap Google Photos settings, tap Back up & sync, and set Backup quality to Original quality. This stops Google from re-encoding your uploads to HEIC.
Pros and Cons
Converting existing HEIC files in Google Drive is the fastest way to get usable JPGs right now. The tradeoff is that you have to repeat the process for new uploads unless you change the source settings. Switching the iPhone to Most Compatible mode is the permanent fix, but it increases photo file sizes on your phone, which eats storage. Disabling Storage Saver in Google Photos preserves your original format but uses more cloud storage quota. For most users, the best combo is Most Compatible on the phone for new photos plus a converter bookmark for cleaning up any existing HEIC files in Drive. That keeps everything as JPG going forward with minimal ongoing effort.
