Convert Apple HEIC photos to universal JPG format — batch process, adjust quality, all in your browser with zero uploads.
Click to browse or drag & drop HEIC files
Supports HEIC files up to 50 MB each
The fastest, most private way to turn Apple HEIC photos into universally compatible JPGs — right in your browser.
Apple's default HEIC format is space-efficient but not universally supported. Convert to JPG with one click — no software to install.
Convert dozens of HEIC photos simultaneously. Our parallel processing engine handles them all at once — each file shows individual progress.
Control output quality from 10% to 100%. Higher quality preserves more detail; lower quality creates smaller files. See file size changes in real time.
HEIC decoding runs entirely in your browser using WebAssembly. No internet connection needed after the page loads — convert anywhere.
Need lossless output? Switch to PNG format. JPG is great for photos; PNG preserves every pixel for graphics and screenshots.
Your HEIC photos never leave your device. All decoding and conversion happens locally — no uploads, no servers, no one sees your images.
Three simple steps to turn Apple HEIC photos into standard JPGs.
Click the upload area or drag-and-drop one or more HEIC files. Each file can be up to 10MB.
Choose between JPG and PNG output. For JPG, drag the quality slider to balance between file size and image quality. Changes preview as you adjust.
Click Download to save each converted file, or use Download All for batch conversions. Files are automatically named with the .jpg extension.
Everything you need to know about converting HEIC to JPG with SlimImg.
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It saves 50% more space than JPG but isn't supported by many websites, apps, and older devices. Converting to JPG makes your photos universally compatible.
JPG is a lossy format — some quality reduction occurs. At 90-100% quality, the difference is nearly invisible. For completely lossless conversion, choose PNG output, though file size will be larger.
Yes. SlimImg runs entirely in your browser and works on any device — Windows, Mac, Android, iPhone, Linux. Our WebAssembly decoder handles HEIC files directly without requiring Apple software.
There's no hard limit — you can batch convert as many HEIC photos as you want. All files process in parallel, and each one shows individual progress. Each file can be up to 10MB.
Never. All HEIC decoding and JPG conversion happens entirely in your browser using WebAssembly and Canvas API. Your photos never leave your device — 100% private and secure.
HEIC Live Photos and Burst sequences contain multiple frames. Our converter processes the primary HEIC image file — the still photo portion. For animated Live Photos, you'll need a dedicated video conversion tool.
HEIC is about half the file size of JPG at similar quality, which is why iPhones use it. But JPG works everywhere. Convert HEIC to JPG when sharing or uploading to sites that don't support HEIC.
Windows doesn't natively open HEIC files. Use our converter to turn them into JPG instantly — no software install needed, works in any browser.
HEIC is Apple's default photo format since iOS 11, and it is a good one — roughly half the size of an equivalent JPG. The problem is not the format, it is that support outside Apple's ecosystem is inconsistent. Here is what actually happens on each platform we hear about most, and whether conversion is the fix.
| Platform | Opens HEIC? | What actually happens |
|---|---|---|
| Windows 10 / 11 (Photos app) | No | Shows nothing or reports an unsupported format until you install the separate HEIF Image Extensions from the Microsoft Store. On a locked-down work machine you often cannot install it at all — this is the single most common reason people end up here. |
| Android (older than 10) | Sometimes | Many devices display a grey placeholder or silently fail to attach the file, even though the gallery app appears to show a thumbnail. Newer Android versions and Samsung's own gallery handle it. |
| Instagram, Facebook, LinkedIn, X | Sometimes | Most now accept HEIC on upload and re-encode it server-side — but the re-encode is out of your control, and some tools (schedulers, older mobile web uploaders) reject the file outright. Converting first means you know what gets published. |
| Email (Outlook, corporate mail, most webmail) | No | Attachments frequently arrive as an unopenable file or get stripped by the mail gateway. This is the case where converting is not optional — the recipient simply cannot open what you sent. |
| Web forms, CMS, print shops, job portals | Sometimes | A long tail of upload widgets accept a fixed list of extensions. Anything not on that list is rejected at the front end, usually with a vague 'invalid file' message and no explanation. |
| iPhone, iPad, Mac | Yes | Full native support, including editing and Live Photos. There is no reason to convert for your own use on Apple hardware. |
| Chrome, Safari, Edge, Firefox (recent) | Yes | All current versions decode HEIC, which is why our converter works entirely in your browser without uploading anything. |
The pattern: HEIC fails wherever the receiving software was built without Apple's codec, and the failure is usually silent or vaguely worded. If you are sending photos to a Windows user, an older Android phone, a corporate inbox, or an upload form, convert to JPG first. If the photos are staying on your own Apple devices, leave them as HEIC and keep the smaller files.
Ready to convert? Use the HEIC to JPG converter — it runs entirely in your browser, so nothing is uploaded. For the format trade-offs in more detail, see HEIC vs JPG. If the photos need a smaller size as well, the image resizer handles the dimensions first.
