How to convert HEIC
to JPG

If you use an iPhone, your photos are saved in HEIC (High Efficiency Image Container) format by default. While HEIC is efficient, many websites, printers, and older devices refuse to open it. Converting to JPG (JPEG) ensures your photos work everywhere.

What is HEIC and why does it cause so much trouble?

HEIC (High Efficiency Image Container) is Apple's default photo format introduced in iOS 11. It uses HEVC (H.265) compression, which achieves roughly twice the compression of JPEG at the same visual quality. For a 12-megapixel iPhone photo, a HEIC file might be 3–4MB, while the same photo saved as JPEG would be 5–7MB. That sounds great until you try to share the file with someone who doesn't use an Apple device.

The compatibility wall is real. Windows 10's built-in Photos app didn't add HEIC support until the Fall Creators Update (2017), and even then it requires downloading a free codec pack from Microsoft. Many older versions of macOS Preview can't open HEIC natively. Linux has support through ImageMagick and darktable, but neither is pre-installed. And most web browsers — Chrome, Firefox, Safari — cannot display HEIC images directly in a page. If you're running a website, uploading a HEIC photo as a profile picture won't work. If you're applying for a visa and the portal accepts only JPG or PNG, your iPhone photo is useless without conversion.

HEIC vs JPG: what changes in the conversion?

The pixel dimensions stay exactly the same. A 4032×3024 HEIC from an iPhone 14 Pro becomes a 4032×3024 JPG. Nothing is cropped, resized, or discarded pixel-wise. What changes is the compression algorithm. HEIC uses a modern predictive coding scheme that JPEG can't match. When you reconvert to JPEG, you're moving from one lossy format to another lossy format. A small amount of generational loss is theoretically possible, but at 92% JPEG quality the difference is invisible even when you zoom in and look at fine hair texture, fabric weave, or gradient skies.

The bigger risk is quality settings. Some online converters default to 70–80% JPEG quality to save server storage, which produces visible compression artifacts. PixelFix Pro defaults to 92%, which is visually indistinguishable from the original for all practical purposes and still produces reasonable file sizes.

Privacy and security: why no-upload conversion matters

When you upload a photo to a third-party converter, you're sending potentially sensitive personal content to an unknown server. The file passes through multiple network hops, may be cached on intermediate servers, and is stored on the converter's system for some period — often hours or days. For casual landscape photos this inconvenience is minor. For passport photos, ID documents, medical images, or private family photos, sending them to a third-party server is an unnecessary exposure risk.

PixelFix Pro runs the conversion entirely in your browser using the heic2any library loaded from a public CDN. The library is a pure JavaScript implementation — it does not make network requests during conversion. You can disconnect from the internet before loading a HEIC file, and the conversion still works because everything executes locally.

Can I batch convert HEIC to JPG?

Currently, PixelFix Pro's HEIC converter works one file at a time per browser tab. This isn't an arbitrary limitation — it's dictated by how the heic2any library works and browser tab memory constraints. In practice, most iPhone users convert photos one at a time when sharing specific images. If you have 50+ HEIC files to convert, the fastest workflow is to open PixelFix Pro in one tab, drag each file in sequence, and click Download. The entire process takes under 10 seconds per photo on a modern device.

An alternative is to use the Batch Editor on the main PixelFix Pro page. It supports HEIC input files directly, and you can process up to 50 images at once, converting them all to JPG and downloading the results as a ZIP file. This is the preferred method for bulk HEIC conversion.

HEIC on Mac: built-in options vs browser converters

On a Mac running macOS High Sierra (2017) or later, the built-in Preview app can open and export HEIC files as JPEG without any additional software. Open the file in Preview, go to File → Export, choose JPEG as the format, adjust quality if needed, and save. This works well for individual files.

The Mac's built-in Photos app can also batch-export an entire HEIC library to JPEG by selecting all photos, right-clicking, and choosing Export. However, this approach requires iCloud Photos to be enabled (or photos to be in the local library), and the export settings apply to the entire selection — you can't set a custom quality per photo.

A browser-based converter is preferable when you're working on a PC or Chromebook, when you don't want to install anything, or when you're already on a website and need to convert an email attachment or downloaded image without switching apps.

The easiest way to convert HEIC to JPG online

Many "free" HEIC converters ask you to upload your photos to their server. That means your private images are stored on someone else's computer — possibly for hours or days. PixelFix Pro is different:

1. Drop your HEIC file directly from your iPhone or Mac onto the canvas
2. The heic2any library converts it to JPEG inside your browser
3. Download the JPG instantly — it never touched a server

The conversion runs at 92% quality by default, which is visually indistinguishable from the original for everyday use. For archival or large prints, keep the original HEIC file alongside the converted JPG.

How do I send HEIC photos from iPhone to my PC?

The easiest method: open PixelFix Pro on your PC, email the HEIC file to yourself from your iPhone, open it in the browser, and it converts automatically. Alternatively, use AirDrop to send HEIC to a Mac, then open in the browser.

Can I convert HEIC to JPG without losing quality?

HEIC to JPG conversion is inherently lossy because JPG uses a different compression algorithm. However, at 92% quality the difference is imperceptible for screens, social media, and standard prints. If you need lossless output, convert HEIC to PNG instead (file size will be larger).

Can I batch convert multiple HEIC files to JPG?

Currently, PixelFix Pro converts one file at a time per browser tab. For multiple HEIC photos, open each in a new tab or use the Images → PDF tool to bundle them, then convert the pages back to images from a PDF viewer.

HEIC to JPG on Mac vs online converter

On a Mac, you can use the built-in Preview app to export HEIC as JPG. But Preview requires opening each file individually and doesn't support batch conversion or exact quality targets. An online browser-based converter is faster when you're already working on a website or email attachment.

Frequently asked questions about HEIC conversion

After converting, you may want to compress the JPG to meet an upload size limit, or strip EXIF metadata including GPS location before sharing. For batch conversion of multiple HEIC files, use the Batch Editor.
