Converting one HEIC photo is easy. Converting an entire camera roll of hundreds or thousands of photos is a different challenge, and doing it one file at a time would take all day. Whether you are backing up your library to a Windows PC, preparing photos for a website, or sharing a whole trip's worth of pictures with someone who cannot open HEIC, you need a batch method. Our HEIC to JPG Converter handles multiple files at once, and this guide covers the fastest approach on every platform.

Below you will find batch conversion methods for the online tool, your iPhone, a Mac, and a Windows PC, so you can pick whatever fits the device your photos live on and the number you need to convert.

Why Batch Convert Your Camera Roll?

There are plenty of reasons to convert a whole set of HEIC photos at once rather than handling them individually:

  • Backing up to a non-Apple device where HEIC may not open.
  • Sharing an event or trip album with friends or family on Windows or Android.
  • Uploading many photos to a website that only accepts JPG.
  • Archiving for the long term in a format you know will always be readable.
  • Editing in software that does not support HEIC.

In all these cases, batch converting saves enormous time. If you are not sure why HEIC causes these issues, our explainer on what a HEIC file is gives the background.

How to Batch Convert HEIC to JPG Online

The online method is the most universal because it works the same on any device and handles many files in one pass.

  1. Open the HEIC to JPG tool in your browser.
  2. Select multiple HEIC files at once, or drag a whole selection into the upload area. On a computer you can use Ctrl+A or Command+A to select an entire folder.
  3. Let the tool convert all the images. They process together rather than one by one.
  4. Click Download all to save the JPGs as a single ZIP file, then extract them.

This is ideal for a few dozen to a few hundred photos and requires nothing installed. For very large libraries, you may want to split them into batches so downloads stay manageable.

How to Batch Convert HEIC on iPhone

You can convert many photos right on your iPhone without a computer:

  1. Open Photos and tap Select, then tap each photo you want, or drag across several to select a range.
  2. Tap the share icon and choose Copy Photos.
  3. Open the Files app, go to a folder, press and hold, and tap Paste. The photos are saved as JPGs.

This built-in trick converts whatever you select in one action. For an even cleaner long-term setup, consider switching your camera so future photos are already JPG, as explained in how to stop your iPhone shooting HEIC.

How to Batch Convert HEIC on Mac

Macs are excellent for bulk conversion thanks to the Photos app and Preview.

  1. In Photos, select all the images you want with Command-click or a range selection.
  2. Choose File > Export > Export Photos.
  3. Set the format to JPEG, pick your quality, and click Export to a folder.

Alternatively, select multiple HEIC files in Finder, open them all in Preview, select every thumbnail, and use File > Export Selected Items to convert them together. Our full Mac walkthrough, including an Automator shortcut for repeat jobs, is in converting HEIC to JPG on Mac.

How to Batch Convert HEIC on Windows

Windows has no built-in HEIC batch export, so the online tool is usually the best route:

  1. Copy your HEIC photos from your iPhone to a folder on your PC.
  2. Open the HEIC to JPG tool, select all the files, and let them convert.
  3. Download the ZIP of JPGs and extract it.

This avoids installing codecs or extra software. For more on Windows-specific HEIC handling, see opening HEIC on Windows.

Comparing the Batch Methods

Each method has a sweet spot:

  • Online tool: Best all-rounder, works on any device, no setup, ideal for tens to hundreds of files in one go.
  • iPhone Files trick: Best when you are away from a computer and converting a moderate selection.
  • Mac Photos or Preview: Best for large libraries already on a Mac, with offline processing and quality control.
  • Windows plus online tool: Best path on a PC, since Windows lacks native batch export.

For most people moving photos between an iPhone and a Windows machine, the online converter is the least hassle and the most consistent. It is worth matching the method to the size of the job as well: a quick handful of holiday snaps is fine through any route, while several thousand archived photos benefit from the structured, batch-by-batch approach so nothing slips through and no single download becomes unwieldy. Whichever path you take, the end result is the same set of universally compatible JPGs.

Tips for a Smooth Batch Conversion

  • Work in batches of a few hundred at a time for very large libraries so downloads and processing stay quick.
  • Keep your originals until you confirm the JPGs look right, since converted files take more space.
  • Mind the storage. A converted JPG library is larger than the HEIC original, so make sure you have room.
  • Organize after converting by saving JPGs into clearly named, dated folders.

If your goal is to upload these photos somewhere and a site has been rejecting HEIC, our guide on why you cannot upload HEIC explains the fix. And if you need formats other than JPG, you can batch convert to PNG for transparency or use our HEIC to PDF tool to bundle document photos into one file.

How to Organize a Large HEIC Library Before Converting

Converting thousands of photos goes far more smoothly if you prepare the library first rather than dumping everything into a converter at once. A little organization up front prevents duplicates, missed photos, and unwieldy downloads.

  1. Group by event or date: Use albums or dated folders so you convert in logical chunks, such as one trip or one month at a time.
  2. Weed out what you do not need: Delete blurry shots and duplicates before converting so you are not doubling files you will discard anyway.
  3. Decide on originals: Choose whether you are keeping the HEIC originals alongside the JPGs or replacing them, and structure your folders accordingly.
  4. Convert in batches: Process a few hundred at a time so each download is a manageable ZIP rather than one enormous file.

This approach keeps you in control of a big job and makes it easy to confirm every photo converted correctly before deleting anything.

Managing Storage After a Large Batch Conversion

Because JPG files are larger than HEIC, converting a big library noticeably increases how much space your photos occupy. Planning for that avoids running out of room mid-conversion:

  • Check available space first: A converted library can be close to double the size of the HEIC original, so make sure your drive or device has room.
  • Convert to external or cloud storage when working with very large sets, so the JPGs land somewhere with plenty of capacity.
  • Decide on a single source of truth: Keeping both HEIC and JPG copies doubles storage, so many people keep just the JPGs once converted, or archive the originals offline.
  • Consider WebP for archives: If you want broad compatibility with smaller files than JPG, converting to WebP is a modern middle ground.

A few minutes of planning here keeps a large conversion from filling your storage unexpectedly.
