Why Cloud Services Store HEIC Without Converting
When you back up iPhone photos to Google Photos, Google Drive, iCloud, or Dropbox, the files are uploaded in their original format. Since iOS 11 (2017), that format is HEIC (High Efficiency Image Container) — Apple's default camera format that produces files roughly 50% smaller than equivalent JPGs.
Cloud services treat themselves as faithful storage: they preserve whatever you upload, byte for byte. This is actually a good thing for data integrity, but it creates a practical problem. When you download those photos to a Windows PC, share them with Android users, or try to insert them into a document, HEIC files often cannot be opened without additional software.
The solution is straightforward: download the HEIC files from your cloud service, convert them to JPG using Convertio.com, and optionally re-upload the JPGs if you need them in the cloud in a universally compatible format.
Google Photos: Download Behavior and HEIC Workarounds
Google Photos can display HEIC files perfectly in the web interface and mobile app. However, the download behavior does not include format conversion:
Standard download
When you click Download (or press Shift+D) on a photo in Google Photos, the file is saved in its original upload format. If it was uploaded as HEIC from an iPhone, you get an HEIC file. There is no setting in Google Photos to change the download format.
The "Save Image As" workaround
In the Google Photos web interface (photos.google.com), you can open a photo, right-click it, and choose "Save Image As" from the browser menu. This saves the rendered preview as a JPG file. The catch: you get the display-resolution version, not the full-resolution original. For casual sharing this may be acceptable, but for printing or archival purposes the quality loss matters.
Google Takeout for bulk export
Google Takeout (takeout.google.com) lets you export your entire photo library as a ZIP archive. However, even Takeout delivers photos in their original format — HEIC files remain HEIC. After downloading the archive, you can batch-convert all HEIC files to JPG using Convertio.com.
Summary: Google Photos has no built-in HEIC-to-JPG conversion. The "Save Image As" trick works for individual photos but sacrifices resolution. For full-quality conversion, download the original HEIC and convert it externally.
Google Drive: Preview vs. Download
Google Drive handles HEIC files differently from Google Photos because it is a general-purpose file storage service, not a photo management tool.
HEIC preview support
The Google Drive web interface can preview HEIC images when you double-click them. The preview renders the image as a JPG in the browser, making it viewable on any device. This might give the impression that Google Drive "converts" the file, but it does not — the original HEIC data is untouched.
Downloading from Google Drive
Clicking Download in Google Drive always delivers the original file. An HEIC file remains an HEIC file. Google Drive is purely a storage service and does not include any built-in format conversion tools.
The complete workflow
- Open drive.google.com and locate your HEIC files.
- Select one or more files, right-click, and choose Download. Multiple files are automatically zipped.
- Open convertio.com/heic-to-jpg and drag the downloaded HEIC file(s) onto the converter.
- Click Convert, then download your JPG files.
- Optionally, upload the converted JPGs back to Google Drive for universal access.
iCloud: The One Service That Partially Auto-Converts
Among major cloud services, iCloud is the only one that offers some degree of automatic HEIC-to-JPG conversion — but only under specific conditions.
iCloud.com downloads
When you visit icloud.com/photos from a Windows PC and download photos, iCloud automatically converts HEIC to JPG before the download reaches your computer. This is Apple's compatibility feature for non-Apple devices. The conversion happens server-side, so you receive ready-to-use JPG files.
iCloud for Windows app
The iCloud for Windows desktop app syncs your photo library to a local folder. In the app settings, you will find the option "Keep High Efficiency Original If Available":
- Checked: Both the HEIC original and a JPG copy are downloaded, which doubles storage usage.
- Unchecked (default): Only the JPG version is downloaded — Windows-compatible and ready to use.
This setting works well for photos synced through iCloud Photos. However, files stored in iCloud Drive (as opposed to iCloud Photos) are not converted — they download in their original HEIC format regardless of this setting.
Limitation: iCloud's auto-conversion only works for photos in iCloud Photos when accessed from a non-Apple device. HEIC files shared via iCloud Drive links, AirDrop, or email are not automatically converted and still need external conversion.
Dropbox: Camera Upload Format Settings
Dropbox offers a proactive solution: you can configure the mobile app to convert HEIC to JPG before uploading. This prevents the problem entirely for new photos.
Configuring Camera Uploads
- Open the Dropbox app on your iPhone.
- Tap your account icon, then the gear icon (Settings).
- Tap Camera Uploads.
- Find "Save HEIC Photos As" and select JPG.
From this point forward, all new camera uploads will be converted to JPG on your phone before being uploaded to Dropbox. The conversion happens locally, so the files stored in Dropbox are already in JPG format and will work on any device.
Existing HEIC files in Dropbox
The Camera Uploads setting only applies to future uploads. HEIC files already stored in Dropbox remain in HEIC format. To convert them:
- Download the HEIC files from Dropbox to your computer.
- Convert them to JPG using Convertio.com.
- Upload the JPGs back to Dropbox and delete the old HEIC versions if desired.
The trade-off
Converting to JPG at upload time means files are roughly twice as large as they would be in HEIC format. If Dropbox storage space is a concern, consider keeping the original HEIC files and only converting to JPG when you need to share or use the photos on non-Apple devices.
Cloud Services HEIC Handling: At a Glance
| Service | Previews HEIC | Downloads as JPG | Notes |
|---|---|---|---|
| Google Photos | Yes | No | "Save Image As" gives JPG but at reduced resolution |
| Google Drive | Yes | No | Pure storage — no conversion features |
| iCloud (web) | Yes | Yes | Auto-converts for non-Apple browsers |
| iCloud for Windows | N/A (sync) | Yes* | Only when "Keep High Efficiency" is unchecked |
| Dropbox | Yes | No | Can convert at upload time via Camera Uploads setting |
The Universal Method: Download, Convert, Re-Upload
Regardless of which cloud service you use, the most reliable way to get JPG versions of your HEIC photos follows the same three steps:
- Download the HEIC files from your cloud service to your computer. Most services let you select multiple files and download them as a ZIP archive.
- Convert the HEIC files to JPG using the converter below (or at the top of this page). Drag and drop multiple files for batch conversion.
- Re-upload the converted JPGs back to your cloud storage, share them via email, insert them into documents, or use them anywhere JPG is supported.
This approach works with every cloud storage service — not just the four covered above. OneDrive, Box, pCloud, Mega, or any other service that stores HEIC files as-is can be handled with the same download-convert-upload workflow.
Why JPG is still the universal standard
HEIC is technically superior to JPG — smaller files, better quality, support for transparency and image sequences. But compatibility is what matters in practice. JPG is supported by virtually every device, browser, email client, content management system, social media platform, and office application ever made. When you need to share photos with anyone, on any device, JPG is the safe choice.
