Preview HEIC and HEIF files locally in your browser
Choose a HEIC or HEIF file, preview the primary image, switch between supported top-level images, and inspect available container details. The file stays on your device.
Local and private
The file is decoded in the browser and is not uploaded for preview.
Multi-image and file details
Switch between supported top-level images and inspect dimensions, metadata, color profile, thumbnails, and auxiliary items.
How to Open a HEIC File Online
Open the file in three steps: choose it, preview the primary image, then switch images or inspect details.
- 1
Choose a HEIC or HEIF file
Drop the file into the viewer or choose it from your device. The file is processed locally in your browser.
- 2
Wait for the image preview
The primary image appears first after the file is decoded.
- 3
Inspect the image and choose the next action
Switch between supported top-level images or inspect dimensions, metadata, color profile, thumbnails, and auxiliary image details.
| Task | Use | Result |
|---|---|---|
| See what the HEIC contains | HEIC Viewer | Preview without creating another file |
| Upload or share a compatible photo | HEIC to JPG | Separate JPG copy |
| Use a PNG editing workflow | HEIC to PNG | Separate PNG copy |
| Reduce HEIC file size | Compress HEIC | Compressed HEIC copy |
Inspect the Image and Available HEIC File Details
The details exposed by a HEIC viewer depend on the container, decoder, and data stored in the file. Available file details vary by the HEIC container, stored data, and browser decoder.
- Basic file information: filename, file size, MIME hint, and container brands.
- Image information: pixel dimensions, primary image, image count, and supported thumbnails.
- Visual properties: orientation, alpha support, color information, and preview method when available.
- Additional data: metadata blocks, auxiliary images, depth-related items, and regions when the decoder exposes them.
HEIC Files Can Contain Multiple Images or Auxiliary Data
HEIF can store more than one image and related items. A normal iPhone photo may expose one primary image, while another file can include thumbnails, bursts, depth data, auxiliary images, or other items.
- Primary image: The viewer displays the primary supported image first when one is available.
- Additional images: use the available image list or thumbnails when the viewer exposes them.
- Unsupported content: keep the original because a preview may not reproduce every item in the container.
- Live Photos: the motion portion usually exists as a related video asset rather than as a normal still-image preview.
Why a HEIC File May Not Open
A failed preview does not necessarily mean the HEIC format is unsupported in every application. The problem can be specific to the file, encoding feature, transfer, extension, or decoder.
- Damaged or incomplete file: retry with the original source rather than a partial download.
- Wrong extension: a file renamed to .heic may contain another format.
- Unsupported encoding detail: some HEIF features or profiles may not be handled by the current decoder.
- Multi-image or auxiliary item: the main item may be missing or unreadable even when other container data exists.
Do not rename the extension to fix compatibility
Changing .heif, .jpg, or another extension to .heic does not convert the encoded file.
HEIC viewer FAQ
Answers about opening, previewing, inspecting, troubleshooting, multi-image files, metadata, and local browser processing.
Choose a HEIC or HEIF file in the viewer and wait for the supported image preview to appear.
No. The viewer is intended to decode and display the file. Use a conversion page only when a separate JPG, PNG, WebP, or PDF is needed.
Yes. HEIF can contain multiple images and auxiliary data, although not every HEIC file does. The viewer may expose a primary image and additional supported items.
Available details can include filename, file size, dimensions, image count, primary-image information, color information, metadata blocks, thumbnails, and auxiliary items. The exact fields depend on the file and decoder.
The file may be damaged, incomplete, mislabeled, protected, or encoded with a feature that the current decoder does not support. Retry with the original file and compare it with another known HEIC image.
The viewer can display supported metadata when it is available, but not every EXIF, GPS, HDR, depth, or auxiliary field is guaranteed to be decoded. Keep the original file whenever this data matters.
No. This page is for opening and inspecting HEIC files. Related conversion tools create new output files.
