Convert Multiple HEIC Photos to JPG — Batch, Free, Private
iPhones and iPads shoot in HEIC (High Efficiency Image Container) by default because it packs roughly twice the image quality of JPEG at the same file size. The catch is compatibility: Windows, many websites, and older apps cannot open HEIC files without extra software. This tool converts up to 50 HEIC photos to JPG at once, entirely inside your browser — nothing is uploaded to a server.
Why convert your whole camera roll?
- Sharing with non-Apple users. WhatsApp on Android, Windows Photos, and most online services display JPG without any plugins. Sending HEIC often results in a broken image icon or a download prompt.
- Uploading to websites. Product marketplaces, social media platforms, and profile photo uploaders frequently reject HEIC files. Converting to JPG first avoids the “unsupported format” error.
- Long-term archiving. JPG has two decades of universal support. If you are archiving photos to an external drive or cloud service you plan to access years from now, JPG is the safer bet.
- Software compatibility. Many photo editors, RAW processors, and print services support JPG natively while HEIC requires an optional codec install.
Quality and file size
Each conversion uses a quality setting of 0.92 (out of 1.0), which produces JPGs that are visually indistinguishable from the original at roughly 85–95% of the HEIC file size. Because HEIC and JPG use fundamentally different compression algorithms, the exact ratio varies per image. The output will typically be slightly larger than the HEIC source but still much smaller than an uncompressed TIFF.
How the batch download works
After conversion, you can download each JPG individually or click Download All as ZIPto get all converted images in a single archive. The ZIP is assembled locally using the fflate library — no server involved.
Tip — disable HEIC on iPhone
To stop your iPhone shooting in HEIC: go to Settings → Camera → Formats and select Most Compatible. This makes the camera write JPG directly, which is useful if you regularly share photos with Windows users.
