iPhone has shot HEIC by default since iOS 11. That means most photos taken on an iPhone after 2017 are HEIC files — and many apps, websites, and older Windows machines can't open them without extra software. Converting to JPG solves the compatibility problem in seconds.
Why HEIC files won't open everywhere
HEIC uses the HEVC codec (also called H.265). HEVC is a licensed format, and Microsoft chose not to bundle the codec in Windows by default — it's available as a paid extension from the Microsoft Store. That licensing cost is the reason your Windows PC shows a blank thumbnail or an error when you try to open a .heic file.
macOS and iOS open HEIC natively because Apple built the codec in. Android support varies by version and manufacturer. Most web upload forms, social platforms, and older software only accept JPG, PNG, or WebP — not HEIC.
JPG is universally supported because it has been the standard since the early 1990s and carries no per-device licensing cost. Converting to JPG trades a small amount of storage efficiency for compatibility everywhere.
How to convert HEIC to JPG online
Go to the HEIC to JPG converter. Click "Upload" or drag your HEIC file onto the drop zone. The file is processed on the server — no software installation required.
Once processing finishes, click the download button. The file downloads as a .jpg with the same filename. The whole process takes under 10 seconds for a typical iPhone photo.
Choosing a quality setting
JPG quality 85-92 is visually indistinguishable from the original HEIC on any standard display. At quality 85, file sizes run roughly 40-60% smaller than quality 100 with no perceptible difference on screen. This range is the right choice for sharing, social media, and email.
Drop to quality 70-80 if you need smaller files and the image isn't going to be enlarged or printed. Anything below 70 introduces noticeable compression artifacts, especially in areas of flat color like skies or walls. Quality 90+ is appropriate if you plan to edit the JPG further after converting.
What actually changes in the conversion
The image data — colors, exposure, all the visual content — converts cleanly. EXIF metadata (date taken, GPS coordinates, camera model, lens info) is preserved in the JPG output.
What does not transfer: the depth map from Portrait mode photos. HEIC can store a secondary depth image alongside the main photo, which powers the blur effect in editing apps. That depth layer does not have a JPG equivalent, so it's dropped during conversion. The main photo looks normal; you just lose the ability to re-edit the depth effect later.
If you need to keep your photos in a lossless format rather than JPG, the HEIC to PNG converter is an alternative — PNG preserves every pixel without compression.
Converting multiple HEIC files at once
The converter accepts multiple files in a single upload. Select all your HEIC files at once in the file picker, or drag a group onto the upload zone. Each file is processed and packaged into a ZIP for download.
If you're converting a large batch and file size matters — for example, uploading to a website — run the output JPGs through the image compressor afterward. That lets you tune quality and target file size across the whole batch.
The fastest path to a compatible file
For one-off conversions or small batches, an online converter beats installing software. Upload the HEIC, download the JPG, done. Use quality 85-90 as your default — it gives you a file any app or platform will accept, at a fraction of the original file size, with no visible quality difference.
