How to Convert HEIC to JPG (iPhone Photos) on Windows & Mac
You AirDropped or emailed some photos from your iPhone, opened them on your Windows PC, and got a file ending in .HEIC that nothing wants to open. Or you tried to upload one to a job application, an online form, or an old website and got rejected because it "isn't a supported image type." You are not doing anything wrong: that is just Apple's high-efficiency photo format meeting software that expects a plain old JPG.
The fix is simple, and you do not need to pay for an app or sign up for anything. This guide walks through every reliable way to turn HEIC into JPG: a free in-browser converter that never uploads your photos, the built-in tools already on Windows and Mac, and a one-time iPhone setting that stops the problem at the source so your camera shoots JPG from now on.
We'll be honest about the tradeoffs too. HEIC files are smaller and can hold more detail than JPG, so converting does involve a quality and file-size decision. By the end you'll know exactly which method fits your situation, whether you have one photo or four hundred of them.
Why iPhone photos are HEIC (and why JPG just works)
Since iOS 11, iPhones default to saving photos as HEIC, a still-image file built on the HEIF container and the HEVC (H.265) codec. The headline benefit is size: a HEIC photo is often roughly half the size of the equivalent JPG at similar visual quality, and the format can store extras JPG can't, like 10-bit color, depth maps, and Live Photo data. On your iPhone, in Apple Photos, and across newer Apple devices, this is great.
The trouble starts the moment a HEIC file leaves the Apple ecosystem. Plenty of websites, upload forms, content management systems, older photo editors, printing kiosks, and Windows apps simply don't recognize it. JPG, by contrast, is the universal raster format every browser, operating system, and image tool on Earth has understood for decades. That universality is the entire reason to convert. If you want to dig deeper into the technical differences, our HEIC vs JPG comparison breaks down compression, compatibility, and quality side by side.
One thing worth saying up front: converting HEIC to JPG is a one-way simplification. JPG can't carry the depth or wide-gamut data HEIC holds, so you're trading a little capability for maximum compatibility. For sharing, uploading, and printing, that's almost always the right trade.
Convert HEIC to JPG free in your browser (no upload, no signup)
The fastest method that works identically on Windows, Mac, Chromebook, and Linux is FileChange's free in-browser converter, because there's nothing to install and your photos never leave your computer. The conversion runs entirely in your browser tab using a JavaScript HEIC decoder (heic2any) — the image data is processed locally and never uploaded to a server, which matters a lot for personal photos.
Here's the whole process. Open the HEIC to JPG converter, then drag your .HEIC files onto the drop zone (or click to browse and select them). You can drop a single photo or a whole batch at once — there's no file-count limit and no hard size cap, just a soft warning around 200MB per file. Click convert, wait a moment while your browser decodes each image, and download the finished JPGs. On a typical photo this takes a second or two per file.
If you'd rather end up with a different format, the same engine produces other types from the same HEIC input — see HEIC to PNG when you need lossless quality or transparency support, or HEIC to WebP for the smallest web-friendly files. For a single photo or a few dozen, this browser method is usually the least-friction option on any platform. And because it's free with no watermark and no account, you can come back any time you hit another stray HEIC.
Convert HEIC to JPG on Windows (built-in and free options)
Windows 11 and modern Windows 10 can usually open HEIC already, because the format is supported once the HEIF Image Extensions are installed. If double-clicking a .HEIC file in File Explorer shows you the photo in the Windows Photos app, you're set; if it doesn't, open the Microsoft Store, search for "HEIF Image Extensions," and install it (it's free). Note that full playback historically also required the "HEVC Video Extensions," which Microsoft charges a small fee for — but for simply viewing and exporting still photos, the free HEIF extension is typically enough.
Once a HEIC opens in the Windows Photos app, converting is easy: open the photo, click the "See more" menu (the three dots), choose "Save as," and pick JPG as the file type in the save dialog. That gives you a clean JPG copy while leaving the original untouched. It's a solid choice for one or two images.
The catch is volume. Windows Photos doesn't offer a true batch "convert all to JPG" command, so doing fifty photos this way is tedious. For large batches, the in-browser converter above (drop the whole folder's worth at once) or the iPhone-side setting in the next section will save you a lot of clicking.
Convert HEIC to JPG on Mac with Preview (no extra software)
Macs read HEIC natively, so you already have everything you need in Preview, the built-in image viewer. For a single image, double-click the HEIC to open it in Preview, choose File > Export, set the Format dropdown to JPEG, adjust the Quality slider if you like, and save. Done — no download, no third-party app.
Preview also handles batches gracefully, which is its real advantage over Windows Photos. Select multiple HEIC files in Finder, open them all in one Preview window, select all the thumbnails in the sidebar (Cmd+A), then choose File > Export Selected Items and export them to JPEG in one pass. That turns a folder of dozens of photos into JPGs in a single operation.
If you prefer not to install or open anything at all — say you're on a managed work Mac, or you just want the same workflow you'd use on any machine — the browser-based HEIC to JPG converter works exactly the same on macOS and keeps your photos local. Either route is genuinely free; pick whichever fits the moment.
Stop the problem at the source: shoot JPG on your iPhone
If you're constantly fighting HEIC files, the cleanest long-term fix is to tell your iPhone to capture JPG-compatible photos in the first place. On your iPhone, open Settings > Camera > Formats and choose "Most Compatible" instead of "High Efficiency." From that point on, the camera saves new photos as JPG (and videos as H.264), and you'll never have to convert again.
There's also a clever middle ground if you want to keep shooting HEIC but share JPG. In Settings > Photos, scroll to "Transfer to Mac or PC" and select "Automatic." With that on, when you connect your iPhone to a computer over USB and import photos, iOS converts them to JPG during the transfer automatically. Similarly, photos you attach in Mail or share to many apps are often delivered as JPG even when stored as HEIC.
The tradeoff is the one we mentioned earlier: "Most Compatible" JPGs are larger and drop HEIC's wider color depth, so you'll use a bit more storage. For most people who mainly share and upload photos rather than archive RAW-grade detail, that's a price well worth paying for never seeing an "unsupported file" error again. Existing HEIC photos already on your phone stay HEIC — so for those, use one of the conversion methods above.
Quality, file size, and what you actually lose
Converting HEIC to JPG is a lossy-to-lossy step, so it helps to set expectations. JPG uses its own compression, and most converters (FileChange included) default to a high-quality setting — around 90 to 92 percent — which is visually indistinguishable from the original for everyday photos. You can usually nudge quality higher for archival copies or lower if you specifically need smaller files for the web.
Expect the JPG to be larger than the HEIC it came from. Because HEIC compresses more efficiently, a 2MB HEIC might land around 3 to 5MB as a high-quality JPG. That's normal and not a sign anything went wrong — you're trading storage efficiency for compatibility. If file size matters for a website or email, consider exporting to WebP instead, or compress the JPG afterward.
Two honest caveats. First, JPG cannot store transparency or the depth/wide-gamut data HEIC can hold; if you need transparency, convert to PNG instead. Second, Live Photos and bursts are special — the "photo" in a Live Photo is a single still frame plus a short video, and converting the still to JPG keeps the picture but drops the motion. For a plain, shareable, uploadable photo, none of that matters, and JPG is exactly what you want.
Frequently Asked Questions
Why won't my HEIC photo open on Windows?
Windows needs Apple's HEIF format support to read .HEIC files. On many Windows 11 PCs it's already there; if not, install the free "HEIF Image Extensions" from the Microsoft Store, after which Windows Photos can open and "Save as" JPG. If you'd rather skip installs entirely, convert the file to JPG in your browser first — then it opens anywhere.
Does converting HEIC to JPG reduce photo quality?
Slightly, but usually not in a way you'll notice. JPG is a lossy format, so re-encoding adds a small amount of compression. A high-quality setting (around 90% or above, which is the default in FileChange) produces a JPG that's visually identical to the original for normal photos. You will lose HEIC-only data like 10-bit color depth and Live Photo motion, though.
Will my photos be uploaded to a server when I convert them?
Not with FileChange. The HEIC-to-JPG conversion runs entirely inside your browser tab using a local JavaScript decoder, so the image data never leaves your device. There's no account, no upload, and no watermark. That's especially reassuring for personal or sensitive photos.
How do I convert a whole folder of HEIC photos to JPG at once?
On a Mac, open all the files in Preview, select them in the sidebar, and use File > Export Selected Items to JPEG in one pass. On Windows, the built-in Photos app has no real batch export, so the easiest route is to drag the whole batch into FileChange's in-browser converter at once — there's no file-count limit — or set your iPhone to "Most Compatible" so future photos are JPG from the start.
Can I change the JPG file size or compression when converting?
Yes. Most tools let you set a quality level. FileChange defaults to a high quality (about 92%) for sharp results; you can raise it for archival copies or lower it for smaller web files. Expect the JPG to be larger than the original HEIC regardless, since HEIC compresses more efficiently — if size is critical, try WebP instead.
Should I just stop my iPhone from making HEIC files?
If you regularly run into compatibility problems, yes — go to Settings > Camera > Formats and choose "Most Compatible" to shoot JPG going forward. You'll use a bit more storage and lose HEIC's wider color depth, but you'll never hit an "unsupported file" error again. Photos already saved as HEIC stay HEIC, so convert those separately.
