HEIC vs JPG: Which Format Should You Use?
If you have ever tried to open an iPhone photo on a Windows PC and seen an unhelpful "cannot open this file" message, you have met HEIC. It is the default photo format on modern iPhones and iPads, and it is excellent at saving space — but support outside the Apple ecosystem is still inconsistent.
JPG, by contrast, is the format everything understands. Choosing between them comes down to a simple trade-off between file size and compatibility. This guide explains both formats and shows when to convert.
What is HEIC?
HEIC stands for High Efficiency Image Container. It is based on the same video-compression family as H.265 (HEVC) and can store a photo at roughly half the size of an equivalent JPG while keeping similar visual quality.
HEIC is also more than a single image: it can hold a sequence, depth data used for Portrait mode, and multiple images in one file. That flexibility is why Apple adopted it as the default camera format.
What is JPG?
JPG (also written JPEG) has been the standard photo format since the early 1990s. It uses lossy compression, meaning some detail is discarded each time the file is saved, but at high quality settings the difference is invisible to the eye.
Its real strength is ubiquity: browsers, email clients, printing services, forms, and social platforms all accept JPG without a second thought.
HEIC vs JPG at a glance
- File size: HEIC is typically 40–50% smaller than a comparable JPG.
- Compatibility: JPG opens on virtually every device, app and website; HEIC support is best inside Apple platforms.
- Quality: both can look excellent at high settings; HEIC retains more quality per byte.
- Features: HEIC can store depth data and image sequences; JPG is a single flat image.
- Editing: repeated JPG saves add compression artifacts; HEIC holds up better across edits.
When should you keep HEIC?
If you live entirely inside Apple devices — shooting on an iPhone, editing on a Mac, and sharing through Messages or iCloud Photos — HEIC is the better default. You get smaller storage use and access to features like Portrait depth data.
When should you convert to JPG?
Convert to JPG whenever a file needs to leave the Apple ecosystem:
- Uploading to a website, form or CMS that only accepts JPG or PNG.
- Sending photos to Windows or Android users who may not open HEIC.
- Submitting photos to a print shop or government portal with format rules.
- Sharing through email or chat apps that do not preview HEIC inline.
How to convert HEIC to JPG without uploading
Conversion is a lossy re-encode, so the goal is to lose as little as possible. The HEIC to JPG tool on this site decodes the original in your browser using WebAssembly and re-encodes it at high quality, then lets you download the results in one batch.
Because everything runs locally, your photos are never sent to a server — which matters for personal, client, or unreleased images.

These tools run entirely in your browser. Nothing is uploaded.
Frequently Asked Questions
Is it better to use HEIC or JPG?
Use HEIC when you stay within Apple devices and want smaller files. Use JPG when the image must open anywhere — websites, forms, Windows or Android devices, and print services.
Does converting HEIC to JPG lose quality?
Converting re-encodes the image, so a small amount of quality is lost. At a high quality setting (around 92%) the difference is usually invisible to the eye.
Can Windows open HEIC files?
Windows can open HEIC with the HEIF Image Extensions add-on, but many older PCs and third-party apps cannot. Converting to JPG avoids the problem entirely.
