- 2

Why use this tool
- Built for batchesConvert dozens of photos in one go with progress shown for each file.
- One ZIP downloadNo need to click through each file — everything arrives in a single archive.
- Original file namesIMG_1234.HEIC becomes IMG_1234.jpg; duplicate names are numbered automatically.
- Works offline once loadedAfter the page and converter have loaded, conversion doesn't need a network connection.
Converting a folder of iPhone photos
When you copy photos from an iPhone to a Windows PC over USB, they often arrive as HEIC files. To convert them all:
- Open the folder in File Explorer (or Finder on a Mac).
- Press Ctrl+A (⌘A on Mac) to select every file, then drag them onto the converter.
- Press Convert. Each file shows its progress; you can keep using the page while it works.
- Click Download all (ZIP) and extract the archive wherever you like.
Non-HEIC files (for example MOV videos from Live Photos) are detected and skipped with a clear message, so you can safely select everything.
How many files can I convert?
The limits are shown on the converter. Because conversion happens on your device, speed depends on its processor and memory. Desktop computers convert several photos in parallel; phones convert one at a time to stay within memory limits.
Converting hundreds of photos? Do it in batches of 50–100. It keeps memory use low and makes the ZIP files easier to handle.
Avoid HEIC files in the first place
On your iPhone, Settings → Photos → Transfer to Mac or PC → Automatic makes iOS convert photos to JPG when you copy them to a computer. Settings → Camera → Formats → Most Compatible saves new photos as JPG. See our guide on converting HEIC photos in bulk for more options.
Frequently asked questions
Can I convert a whole folder of HEIC files?
Yes. Select all files in the folder and drop them onto the converter, then download the results as one ZIP.
What happens to non-HEIC files in my selection?
They're identified by their file signature and marked as unsupported, while all HEIC files are converted normally.
Are file names preserved?
Yes. Each converted file keeps its original name with the new extension. Duplicate names in a ZIP get a number added.
Why does my phone convert one photo at a time?
Decoding high-resolution photos needs a lot of memory. Converting sequentially on phones prevents crashes.
