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.
大多數線上 HEIC 到 JPEG 轉換器會透過遠端伺服器路由您的檔案來處理轉換。這意味著您的照片，即使是短暫的，也存在於您無法控制的基礎設施上。
heictojpeg.io 在客戶端執行整個轉換。您的檔案將被讀取、轉換和下載，而無需傳輸到任何地方。沒有要攔截的上傳步驟，也沒有要刪除的伺服器端副本，因為從未建立過任何副本。
這對於家庭照片、醫療影像、身分證掃描或您不想透過第三方伺服器放置的任何檔案最為重要。
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.

關於品質、隱私、相容性和 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.
