How to Convert HEIC to JPG — Free, In Your Browser

You AirDropped a photo to a friend on Windows and it won't open. You uploaded a picture to a job application or insurance form and got "file type not supported." You emailed a photo and the recipient saw nothing. The culprit is almost always the same: your iPhone saved it as a HEIC file, and the thing on the other end only understands JPG.

This guide covers the fastest free way to convert HEIC to JPG right in your browser, plus the built-in methods on Mac, Windows, and iPhone. We'll also show you how to make your iPhone stop creating HEIC files in the first place — so you never have to convert again.

The fastest no-upload option is FileNaut's HEIC to JPG converter — drop the file, get a JPG, done. Your photo never leaves your browser.

Fastest Method — FileNaut HEIC to JPG (Free, No Upload)

If you just want the JPG and want it now, three steps:

1. Open FileNaut's HEIC to JPG converter in any browser.
2. Drag your .heic file into the dropzone (or click to browse and pick it from your files).
3. Click Convert to JPG, then Download JPG. The output is a high-quality JPG (92% quality) ready to send anywhere.

That's it. The conversion runs entirely in your browser — your photo is never uploaded to any server, no signup is required, and there's no watermark on the output.

Why this matters: Most "free HEIC converter" sites upload your photo, process it on their server, and store it for at least 24 hours. Phone photos often contain faces, location data, documents, or things you'd rather not hand to a stranger's server. Client-side conversion removes that risk entirely.

What Is HEIC, and Why Does Your iPhone Use It?

HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11 (2017). It uses the HEIF standard with HEVC compression, which means it stores a photo at roughly half the file size of a JPG at the same visual quality. It also supports things JPG can't — like Live Photos, depth maps, and wider color.

The catch: support outside Apple's ecosystem is patchy. Windows needs an extra codec, many websites and upload forms reject it, and lots of older software simply can't open a .heic file. JPG, by contrast, opens on literally everything made in the last 30 years. That's the whole reason you're here — you don't need a better format, you need a compatible one.

How to Convert HEIC to JPG on Mac (Preview, Built-In)

macOS opens HEIC natively and can export to JPG — no app to install.

1. Double-click your HEIC file to open it in Preview.
2. Click File → Export… (not Save As).
3. In the format dropdown, choose JPEG.
4. Drag the Quality slider — 80% is fine for web, 100% for print.
5. Click Save.

Batch convert on Mac (best for lots of photos)

If you have a folder of HEICs, don't do them one at a time:

1. Select all the HEIC files in Finder (click the first, Shift-click the last).
2. Right-click → Quick Actions → Convert Image.
3. Choose format JPEG and an image size, then click Convert to JPEG.

This works on macOS Monterey (12) and later and converts the whole batch in seconds. The new JPGs land in the same folder alongside the originals.

How to Convert HEIC to JPG on Windows

Windows 10 and 11 can open and convert HEIC, but only after you install the codec Microsoft splits into two parts.

Using the Photos app (after installing the codec)

1. Install the free HEIF Image Extensions from the Microsoft Store. You may also need HEVC Video Extensions (a small paid item) for some files.
2. Open the HEIC in the Photos app.
3. Click the ⋯ menu → Save as.
4. Choose .jpg in the format dropdown and click Save.

Don't want to install anything? Skip the codec entirely and use FileNaut's HEIC to JPG in your browser — it works on any Windows machine with no setup, and your photo never leaves the device. For most Windows users this is genuinely the faster route.

How to Convert HEIC to JPG on iPhone

Ironically, the device that made the HEIC can also convert it. Two quick ways:

The copy-paste trick (fastest)

1. Open the photo in Photos, tap Share → Copy Photo.
2. Open the Files app, go to a folder, press and hold → Paste.
3. iOS pastes it as a JPG. (This works because the clipboard hands off a JPEG copy.)

Using Shortcuts (one-time setup, then native)

1. Open the Shortcuts app → + for a new shortcut.
2. Add action Convert Image → set format to JPEG.
3. Add action Save to Photo Album. Name it "HEIC to JPG" and add it to your Share Sheet.

After setup, share any photo → "HEIC to JPG" → done. Or just open FileNaut in Safari and convert there — no setup at all.

Stop Your iPhone From Making HEIC Files (The Real Fix)

Converting one file at a time is fine for a photo or two. But if you're constantly fighting HEIC, change the source. You have two good options:

Option 1 — Shoot in JPG from now on

1. Open Settings → Camera → Formats.
2. Select Most Compatible.

Your camera now saves new photos as JPG. The trade-off: files are about twice the size, and you lose HEIC-only features. Your existing HEIC photos are unchanged — this only affects new shots.

Option 2 — Keep HEIC but auto-convert when sharing

1. Open Settings → Photos.
2. Scroll to Transfer to Mac or PC and choose Automatic.

Now your phone keeps the space-saving HEIC originals, but converts to JPG automatically whenever you transfer photos to a computer. Best of both worlds for most people.

Does Converting HEIC to JPG Lose Quality?

A little — but not in a way you'll see. HEIC and JPG are both lossy formats. Converting from one to the other re-encodes the image, which technically discards a small amount of data. At 90% quality or higher (FileNaut uses 92%), the result is visually identical to the original for normal photos.

The bigger change is file size: a JPG is typically 1.5–2× larger than the same HEIC, because JPG's compression is older and less efficient. That's the price of universal compatibility. If the resulting JPG is too big for an upload form or email, run it through Image Compress to hit a specific target size.

One thing to know: Live Photos, depth/portrait data, and any extra layers stored in a HEIC don't survive the conversion — JPG can only hold a single flat image. The photo itself looks the same; the bonus data is dropped.

Converting a Whole Folder at Once

FileNaut's converter handles one photo at a time — perfect for the one-off file you need to send right now. For a large batch, the fastest free routes are:

• On Mac: select all the HEICs in Finder → right-click → Quick Actions → Convert Image → JPEG (covered above). Converts dozens in seconds.
• On Windows: set your iPhone to transfer as JPG automatically (Settings → Photos → Automatic), then import — the photos arrive as JPG with no conversion step.
• At the source: switch your camera to Most Compatible so future photos are JPG from the start.

For other image formats, our Image Converter handles JPG, PNG, and WebP in any direction — all in your browser.
