JPEG is a lossy format, but at a high quality setting — which this tool uses by default — the difference is invisible to the eye in an ordinary photo. What you get in exchange is a much smaller file that opens everywhere: every OS, every app, every upload form that flatly rejects HEIC.
PNG is the better choice when you need pixel-perfect lossless output or a transparent background — screenshots, logos, graphics you'll edit further. For a straight photo you're sharing, printing, or uploading somewhere, JPEG's smaller size and universal support usually wins.
If file size and compatibility are the priority, convert to JPEG. If pixel-for-pixel accuracy or transparency matters more, use our HEIC to PNG converter instead — same local, no-upload approach, different output format.
| Feature | JPEG | PNG |
|---|---|---|
| Compression | Lossy, small quality trade-off | Lossless |
| Transparency | Not supported | Supported |
| Best for | Photos, casual sharing, uploads | Screenshots, logos, editing |
| File size | Smaller | Larger |
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It uses a newer, more efficient compression method than JPEG, so it stores a similar-looking photo in roughly half the file size. The trade-off is compatibility: HEIC is still not fully supported across Windows, many web upload forms, and a lot of non-Apple software, which is why converting to JPEG remains the practical default when you need to share, print, or upload a photo somewhere outside Apple's ecosystem.
JPEG, in exchange for the larger file size, is understood by essentially every device, platform, and piece of software made in the last 25 years. That universal support is the entire reason it's still the default target format for HEIC conversion, even though newer formats like HEIC and WebP are technically more efficient.
大多数在线 HEIC 到 JPEG 转换器会通过远程服务器路由您的文件来处理转换。这意味着您的照片，即使是短暂的，也存在于您无法控制的基础设施上。
heictojpeg.io 在客户端运行整个转换。您的文件将被读取、转换和下载，而无需传输到任何地方。没有要拦截的上传步骤，也没有要删除的服务器端副本，因为从未创建过任何副本。
这对于家庭照片、医疗图像、身份证扫描或您不想通过第三方服务器放置的任何文件最为重要。
Use a broadly supported JPEG when the original iPhone or HEIF photo does not fit the next step in your workflow.
Photos sent from an iPhone show up as unreadable HEIC files. Convert them to JPEG and they open in any Windows photo viewer.
Most platforms and email clients still don't render HEIC properly. Convert first and avoid the broken-image icon.
Application portals, job sites, and government forms routinely reject HEIC uploads outright. JPEG is accepted almost everywhere.
Convert a batch from a recent trip or event so the files play nicely with older apps, printers, and shared drives.
Choose PNG when you need transparency or lossless image quality.
If you'd rather your iPhone save new photos directly as JPEG, go to Settings → Camera → Formats and select Most Compatible instead of High Efficiency. This changes what your camera saves going forward; it doesn't affect photos you've already taken, which is where a converter like this one still comes in.

关于质量、隐私、兼容性和 iPhone 照片的清晰答案。
heictojpeg.io is a free online tool that converts HEIC/HEIF image files, the format used by iPhones, into JPEG format quickly and directly in your browser.
Yes. There are no hidden fees, watermarks, or sign-up requirements. Convert as many batches of files as you need, whenever you need to.
No. heictojpeg.io works with zero sign-up. Just open the site and start converting.
No. This tool uses your browser's built-in processing to convert the file locally on your device. The image data never leaves your computer or phone, so there's nothing to intercept and nothing stored on a remote server.
Yes. The converter creates a new JPEG and does not copy EXIF metadata such as the date taken, GPS location, or camera information from the source photo.
No, and any tool claiming zero quality loss when converting to JPEG isn't being accurate. JPEG uses lossy compression by design. At a high quality setting, the difference is invisible to the eye in ordinary photos, but it is technically not identical to the original.
You can batch convert up to 10 files per session, with a maximum file size of 50 MB per file.
Yes. Since it runs entirely in your browser, heictojpeg.io works on Windows, Mac, Linux, Chromebook, and mobile devices, with no software installation required.
