What HEIF Viewer is for

Use this tool when you just need to open and check a .heif file, especially on Windows where the format often will not open. It decodes the photo in your browser, shows its dimensions and size, and lets you save a copy, with nothing uploaded.

Open and view a .heif file on any device, including Windows and Chromebooks.
Check a HEIF photo's dimensions and file size before converting it.
Preview HEIF photos someone sent you without installing codecs.
Save a quick PNG copy of a HEIF photo you only needed to look at.

Privacy note: This tool runs locally in your browser. Your selected image files are not uploaded to CompressImage.ca. Read more on our promise page.

Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

Use the viewer to confirm a file really is HEIF before converting a whole batch.
On Windows, the viewer avoids the paid HEVC extensions entirely.
Save a PNG copy from the viewer when you want to keep what you opened.
For many files, the converters are faster than opening them one at a time.

What happens to your images?

When you choose a file, your browser reads it locally and creates the processed version on your own device. CompressImage.ca does not receive the original image or the finished file.

That local-first approach is useful for personal photos, client work, screenshots, documents, product images and other files you do not want to upload to a third-party server.

When to use another tool

The best tool depends on what you are trying to fix. Compression reduces file size, resizing changes dimensions, conversion changes format, cropping changes framing, and metadata removal cleans hidden information from the file.

Goal	Best tool
Make a file smaller	Compress Image
Hit an exact file size	Compress Image to Size
Change image dimensions	Resize Image

HEIF Viewer FAQ

What is a HEIF file?

HEIF (High Efficiency Image Format) is a modern image container that stores photos at about half the size of a JPG. Many Android phones and cameras save in it, and Apple's HEIC is a version of the same standard.

How do I open a HEIF file on Windows?

Use this viewer to open it right in your browser, with no codecs or extensions to install. For a permanent fix, convert the photo to JPG or PNG once and it opens in every Windows app.

Can I view HEIF photos on Android, Mac or a Chromebook?

Yes. The viewer runs in any modern browser on any operating system, so the same link works on Android, ChromeOS, Linux, Mac and Windows.

Is my HEIF photo uploaded when I view it?

No. The file is decoded entirely in your browser using WebAssembly, so it never leaves your device, which makes the viewer safe for private photos, IDs and documents.
