Batch Convert HEIC to JPG: Fast, Easy, No Upload Required
You just transferred 200 photos from your iPhone to your Windows PC — and now you have a folder full of .heic files that nothing can open. The thought of converting them one by one sounds like torture.
The good news: batch conversion is fast, free, and you can do it without uploading your photos to any server. Here's how.
Why iPhone Photos Won't Open on Windows
Starting with iOS 11, Apple changed the default photo format from JPG to HEIC (High Efficiency Image Container). HEIC is more compressed — about 30–50% smaller files with the same quality. Great for saving space on your iPhone, but it breaks compatibility with Windows.
Windows doesn't support HEIC natively. You can install Microsoft's free HEIF extensions to view them, but if you need to share these photos with others, email them, upload to social media, or edit them in most software, converting to JPG is the right move.
The Problem With Online Converters
Most online HEIC converters work the same way: you upload your photos to their server, they convert them there, and you download the results. This means your personal photos pass through a computer you don't control. Even briefly, that's a privacy risk.
Some converters:
- Add watermarks or logos to your photos
- Require sign-up and create accounts you have to manage
- Limit how many photos you can convert per day
- Store your data for analytics or resale
- Have questionable security practices
Batch conversion shouldn't require any of that.
The Better Way: Browser-Based Batch Conversion
This tool converts HEIC to JPG right in your browser using WebAssembly — which means the conversion happens on your device, not a server. Your photos never leave your computer.
You can batch convert up to 50 HEIC files at once:
- Select your folder of HEIC photos (all at once)
- Adjust JPG quality if needed (default: 90%, looks great)
- Click Convert
- Download as individual files or ZIP archive
The whole process takes 10–30 seconds depending on how many photos and your computer speed. No upload, no waiting, no sign-up.
Why Batch + ZIP Download Matters
Converting 200 photos one by one would take hours and annoy you. Batch conversion in a browser saves two pain points:
- Speed: Convert dozens of photos in seconds instead of minutes.
- Organization: Download as ZIP archive keeps all converted photos in one file — move to your folder, unzip, done.
Preserving Photo Metadata (EXIF)
When you convert HEIC to JPG, the tool preserves EXIF data — the hidden metadata in every photo: camera model, ISO, shutter speed, GPS location (if enabled), date taken, and more. This is important if you're archiving photos or want photo management software (Google Photos, Lightroom) to read the original capture date and location.

Convert my photos →Quality Settings for Batch Conversion
HEIC already uses efficient compression, so when you convert to JPG, you don't lose much quality. The tool defaults to 90% JPG quality, which looks great on any device and keeps file sizes reasonable.
If you're archiving forever and want maximum quality, increase to 95%–100%. If you're sharing on social media or email and want smaller file sizes, lower to 75%–80%.
Even at 75% quality, JPG conversion from HEIC looks excellent to the human eye. The default 90% is the sweet spot for most use cases.
Bottom Line
Batch converting HEIC to JPG used to mean uploading to a sketchy online tool. Now you can do it privately in your browser, convert dozens at once, and download as ZIP. Your photos stay on your device, the conversion is instant, and it's completely free.
