How to Batch Convert HEIC Files (Hundreds at Once)
When you AirDrop an iPhone album to your laptop, you end up with a folder full of .heic files that almost nothing can open. Converting them one by one is painful. This guide shows you how to batch convert HEIC files — from dozens to several hundred at once — for free, without uploading anything, and with a single ZIP download at the end.
Drag a folder, get a ZIP
Open heictoall.net, drag your entire HEIC folder onto the drop zone (Chrome, Edge, and Firefox support folder drops). Choose the output format — JPG for sharing, PNG for editing, WebP for the web. Click Convert. Each file is decoded and re-encoded in parallel using web workers, and the results are streamed into a ZIP that downloads automatically when finished.
How many HEIC files can I convert at once?
There is no hard limit — only your device's memory. On a modern laptop you can comfortably convert 500–1000 HEIC files in a single batch. On a phone, 50–100 is a safer batch size. If you have thousands of photos, split them into folders by month or by event and convert one folder at a time. The browser will keep memory usage in check and your fan won't spin out of control.
Preserve EXIF and original filenames
All EXIF metadata (date taken, camera model, GPS) is carried over by default, so the converted files keep their original chronology when you sort by "date taken" in Photos, Lightroom, or your file manager. Filenames are preserved with the new extension — IMG_4521.HEIC becomes IMG_4521.jpg. This matters for backups: your existing folder structure and search tools keep working without re-indexing.
Privacy when batch-converting personal albums
Batch converters that upload your photos to a server are a privacy nightmare — you're shipping years of family photos to a third party. heictoall.net does everything locally in your browser. There is no upload progress bar because there is no upload. You can disconnect from the internet after the page loads and the batch will finish without ever touching a server.

FAQ
What's the maximum batch size?
Soft-limited by your device's RAM. ~500 files on a laptop, ~100 on a phone is a comfortable target.
Will all files end up in a single ZIP?
Yes. When the batch finishes you get one ZIP archive with every converted file, ready to extract.
Are filenames preserved?
Yes — only the extension changes. IMG_1234.HEIC becomes IMG_1234.jpg/png/webp/etc.
Is EXIF metadata kept?
Yes. Date, GPS, camera model, and orientation are preserved during conversion.
Does the free tier limit batch size?
No. The 5/day free limit applies to watermark-free output, not to batch size. Larger batches simply add a small watermark unless you upgrade.
