How to Use This Tool

Choose HEIC or HEIFAdd up to 20 files. Native browser decoding is used when available; otherwise a local decoder is loaded.
Set JPEG qualityChoose a higher value for more detail or a lower value for a smaller compatibility copy.
Convert and verifyOpen the JPG after download to confirm rotation, color, and detail before deleting or archiving anything.

Controls and Method

JPEG quality

HEIC pixels are re-encoded as lossy JPEG. The setting affects the new JPEG only and does not modify the original HEIC.

After the Conversion

A converted iPhone photo is still an iPhone photo: often 3000 pixels or more on the long edge and several megabytes. Resizing it and then compressing it is what makes it usable in a form that caps uploads at 2 MB.

If you photographed a document rather than a scene, cropping it square to the page and combining the pages into one PDF produces something a recipient can actually file.

Why HEIC Files Cause Compatibility Problems

HEIF is a container standard that can store efficiently coded images and related information. HEIC is commonly associated with HEVC-coded images in that container. Apple devices use it widely, but older desktop applications, print workflows, and upload forms may accept JPEG while rejecting HEIC.

What the Conversion Keeps and Removes

The converter keeps the browser-decoded pixel image and dimensions. It does not copy EXIF, GPS, capture time, camera model, depth maps, bursts, live-photo relationships, or the original color profile into the JPEG. That metadata removal can be useful for sharing privacy, but it also means the JPG is not an archival replacement for the original.

HEIC and JPG Compared

Practical differences for this conversion
Feature	HEIC source	JPG output
Compatibility	Varies by app and browser	Broad photo support
Encoding	Often HEVC-based within HEIF	Lossy JPEG
Metadata	May contain rich camera data	Not copied by this tool
Sequences and auxiliary images	Can be represented	Not preserved

Practical Uses

Submitting an iPhone photo to a JPG-only form
Opening a photo in older Windows software
Sending a compatibility copy to a print service
Sharing with a workflow that rejects .heic

Verified processing path

Private Browser Processing

Where it runs: The browser first tries native HEIC decoding. If unavailable, the page loads the bundled heic2any library and decodes locally before JPEG canvas export.
Metadata: The output is newly encoded from decoded pixels. Original EXIF fields such as GPS coordinates, camera model, and capture date are not copied to the new file.
Orientation: The browser decodes the displayed pixel orientation before processing. The new file stores the rendered orientation instead of preserving the source EXIF orientation tag.
Transparency: JPEG is opaque. Any decoded transparent pixels are placed on white.
Animation: HEIC and HEIF sequence files are accepted, but only the still image the browser decodes becomes the JPG. Live Photo motion and burst frames are not carried over.
Color: The browser renders into a canvas before export. Embedded ICC profiles are not copied, so wide-gamut or color-managed originals can look slightly different.

Site analytics records page visits and whether this tool finished or failed, but never the image itself, its name or size, or the file you download. See the Privacy Policy for site-wide details.

Important Limitations

HEIC browser support and decode behavior vary.
JPEG re-encoding can change fine detail and file size.
Depth, burst, sequence, and live-photo information are not preserved.
The original should be kept when capture metadata or archival quality matters.

Frequently Asked Questions

What is a HEIC file?

HEIC is a common extension for images stored in HEIF-based containers, especially on Apple devices. The container can use efficient image coding and store additional metadata.

Does HEIC to JPG reduce quality?

It can. JPEG is a new lossy encoding of the decoded HEIC pixels. Use a higher setting and keep the original when quality matters.

Will an iPhone portrait stay upright?

The browser decoder normally applies the stored orientation before canvas export. Check the finished JPG because HEIC support varies across browsers.

Is EXIF metadata preserved?

No. Camera model, GPS, date taken, orientation tags, and other HEIF/EXIF metadata are not copied to the JPG.

Why does HEIC work in one browser but not another?

Native HEIC decoding differs by browser and operating system. This page has a local fallback, but unusual HEIF variants may still fail.
