HEIC to JPG converter

Turn iPhone photos into JPGs that open on Windows, Android, websites and upload forms. The conversion happens on your device, so your photos are never uploaded.

Good to know
  • AVIF output appears only in browsers that can encode AVIF. WebP output is unavailable in a few older Safari versions.
  • Converted files contain no EXIF metadata, so location and camera details are removed. Rotation is applied to the pixels.
  • GIF input uses the first frame only. Multi-image HEIC files (bursts) use the first image.
  • Very large batches are converted one file at a time to keep memory use low.

Why convert HEIC to JPG?

Since iOS 11, iPhones save photos in HEIC (the HEIF image format) when the camera is set to High Efficiency. HEIC files are smaller than JPGs at similar quality, which is why Apple uses them, but plenty of software still refuses them: older Windows PCs, many online forms, some printing kiosks, and photo editors that never added support.

JPG is the safest choice when you just need a photo to open. It works in every browser, every operating system and almost every upload form. The trade-off is size: a JPG of the same photo is usually larger than the HEIC, and JPG has no transparency (photos rarely need it).

How to convert HEIC to JPG

  1. Add your photos. Drop HEIC files on the bay above, choose them with the file picker, or paste them. You can add a whole folder’s worth at once.
  2. Check the settings. JPG is already selected. Quality 90% is a good default. Set a maximum size in KB only if a website limits uploads.
  3. Convert. Conversion starts automatically. Each photo shows its new size and how much smaller or larger it became.
  4. Download. Download photos one by one, or use Download all (ZIP) to save everything in one file.

Settings explained

Quality
Controls JPG compression. 85–92% is visually identical to the original for most photos; below 70% you may notice blockiness in skies and skin.
Max size per image (KB)
Myriadfile searches for the highest quality that fits under your limit, then reduces the dimensions only if it has to.
Max width and height
Shrinks large photos while keeping their proportions. 2048 px on the long side is plenty for sharing; 4032 px is a typical iPhone original.

What happens to location and camera data?

The converted JPGs contain no EXIF metadata. That removes GPS location, camera model and capture settings, which is useful before posting photos publicly. Rotation is applied to the pixels first, so portrait photos still appear the right way up.

If you need to keep the original date and location, keep your HEIC originals as well, or export JPGs from the Photos app instead.

Stop new photos from being HEIC

On an iPhone you can switch the camera to JPG: open Settings → Camera → Formats and choose Most Compatible. You can also keep HEIC on the phone and let iOS convert photos when you copy them to a computer, using Settings → Photos → Transfer to Mac or PC → Automatic (both settings are described in Apple’s HEIF support article).

Troubleshooting

“This HEIC file could not be decoded”
A few HEIC variants (for example some Samsung or camera-app files) use features the decoder does not support. Try exporting the photo from the Photos app as JPG, or send it to yourself by email, which often converts it.
Live Photos
A Live Photo is a still image plus a short video. Myriadfile converts the still. The motion part is a separate MOV file and is not affected.
The page slows down with hundreds of photos
Photos are converted one at a time to save memory, but 100+ full-size photos still need several gigabytes of decoding on the way. Convert in batches of about 100 on phones and older laptops.

Frequently asked questions

Is converting HEIC to JPG free?

Yes. There is no sign-up, watermark or file limit. The site is supported by ads.

Are my photos uploaded anywhere?

No. The HEIC decoder runs inside your browser, and the JPG is created on your device. You can turn off your internet connection after the page loads and it keeps working.

Does converting reduce quality?

JPG is a lossy format, so a tiny amount of detail is lost each time a photo is saved. At 90% quality the difference is not visible in normal viewing.

Why is the JPG bigger than the HEIC?

HEIC uses a more efficient compression method. A JPG at the same visual quality usually takes more space. Lower the quality or set a KB limit if size matters.

Can Windows open HEIC without converting?

Windows 10 and 11 can view HEIC after you install Microsoft’s HEIF Image Extensions and the HEVC Video Extensions from the Microsoft Store. Converting to JPG avoids that setup for everyone you share the photo with.

Can I convert HEIC on my phone?

Yes. This page works in mobile browsers on Android and iPhone. On an iPhone, choose files from the Photos library through the file picker.
