How to Convert HEIC to JPG (Free, No Software Install, 2026)
You emailed a holiday photo and the recipient saw a broken thumbnail. The culprit is almost certainly HEIC - the high-efficiency image format that iPhones save by default. The fix is a 10-second conversion to JPG, but the official routes are clunky and the dodgy converter sites upload your private photos to who-knows-where. This guide explains what HEIC actually is, when you should keep it, when to convert, and the safest free way to do it.
What HEIC is and why your iPhone uses it
HEIC is the file extension Apple uses for images stored in the High Efficiency Image File Format (HEIF), encoded with the HEVC (H.265) codec. The format was finalised in 2015 and shipped on every iPhone from the iPhone 7 onwards. Compared with JPG at equivalent quality, HEIC stores the same photo in roughly half the space - a 12 MP iPhone photo that would be 3.5 MB as JPG is around 1.6 MB as HEIC.
Apple, Microsoft, and Android (Pixel 8+) all decode HEIC natively. The trouble is when you share that file with someone outside that ecosystem: older Windows machines, web upload forms with strict MIME filters, and many older Linux apps simply cannot open the file. That is when you convert to JPG.
When you should and should not convert
Convert to JPG when: emailing to non-iPhone users, uploading to legacy web forms (banking, government), printing through a kiosk with no HEIC support, or embedding in a Word document for an older Office version.
Keep HEIC when: archiving to iCloud or another Apple service, sharing AirDrop to another iPhone or Mac, or editing in any current photo app. You save 40 to 60 percent of the storage.
Stop the problem at the source
iPhone Settings › Camera › Formats › "Most Compatible" makes the camera save new photos as JPG. Use this if you constantly share photos with non-Apple users. Existing HEIC photos are not affected.
Three free ways to convert HEIC to JPG
Method 1: AllToolsHub image converter (recommended for privacy). Open the image converter, drop the HEIC file, choose JPG as the output. Everything happens in your browser; the file never leaves your laptop. Works on any operating system with a modern browser.
Method 2: Mac built-in Preview. Open the HEIC in Preview, File › Export, choose JPEG, set quality 80-90, save. Two-photo batches are fine; for hundreds of photos use a tool with batch mode.
Method 3: Windows Photos app (since 2018). Right-click the HEIC, Open With › Photos, then Save As JPG. If you do not see the HEIC option, install the free "HEIF Image Extensions" from the Microsoft Store. Note that this requires the paid "HEVC Video Extensions" pack on some Windows versions.
Batch converting hundreds of photos
The patience-friendly approach: open the image converter, drag the whole folder of HEIC files onto the drop zone, and let the browser process them in parallel. The tool returns a ZIP of JPGs at the quality you choose. Modern laptops handle a hundred 12 MP photos in under two minutes.
For people on the command line: the open-source libheif ships with a heif-convert tool that handles thousands of files at the cost of one shell command. Mac users can install it with Homebrew (brew install libheif), Linux via apt (sudo apt install libheif-examples).
Quality and metadata trade-offs
HEIC stores each photo at higher bit depth (10 bits per channel on newer phones versus 8 bits for JPG). Most viewing devices cannot show 10-bit colour anyway, so the visible quality difference after conversion is essentially zero, but extreme gradients (sunset skies, smoke) can show subtle banding after JPG conversion.
EXIF metadata - date, GPS coordinates, camera model, ISO, shutter speed - is preserved by all three conversion methods above, as long as you do not check a "strip metadata" toggle. If you are sharing photos publicly, do strip GPS data before publishing to avoid revealing your home location.
Common pitfalls
- Live Photos. An iPhone Live Photo is actually a HEIC plus a short MOV video. Conversion to JPG only keeps the still image; the motion is lost.
- Portrait Mode depth data. The depth map used for the artificial background blur lives alongside the HEIC. Converting to JPG bakes in the current blur but discards the editable depth map.
- Multi-image HEIC (burst, panorama). Some HEIC files contain multiple images. A simple converter exports only the primary image - the rest of the burst is dropped. Use a multi-image-aware tool if you need every frame.
Conclusion
HEIC is genuinely a better format than JPG for capture and archival - smaller files, higher bit depth, identical visual quality. The only reason to convert is to share with software stuck in the JPG era. With a browser-based converter that conversion takes seconds and never leaves your device, which is exactly the right level of friction for an occasional compatibility problem.
Pick the method that fits your workflow, keep a stripped-metadata copy for public sharing, and consider flipping the iPhone setting to "Most Compatible" if you only ever share with non-Apple users.
Frequently asked questions
Will conversion reduce my photo quality?
At JPG quality 85 or higher the visible difference from the original HEIC is essentially invisible. At quality 70 you start to see artefacts on smooth gradients and sharp edges.
Are HEIC photos really stored "smaller" than JPG?
Yes - roughly 50 percent smaller for the same visual quality. That is why Apple chose the format. The trade-off is compatibility with older non-Apple software.
Does converting HEIC to JPG lose the GPS location?
Only if you explicitly strip metadata. By default our converter preserves the EXIF data including GPS, camera model, and capture timestamp.
Can I convert JPG back to HEIC?
Yes, although the round-trip will not recover the data that JPG already discarded. The output file will be smaller (because HEIC is more efficient) but no higher quality than the JPG was.
