How to Batch Convert HEIC Photos to JPG or PNG for Free

You just transferred hundreds of photos from your iPhone to your Windows PC or uploaded them to a web platform, and nothing can open them. The files all end in .heic, and most of your software does not recognize the format. Converting them one at a time is not realistic. This guide shows you how to batch convert HEIC photos to JPG or PNG for free using our online tools — no software installation required.

Why HEIC Causes Compatibility Problems

HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads running iOS 11 and later. Apple adopted it because HEIC files are roughly 50% smaller than equivalent JPGs at the same visual quality. That saves significant storage on devices that take thousands of photos.

The problem is compatibility. While Apple devices, recent versions of macOS, and Windows 11 (with the HEIF extension) can open HEIC files, many other systems cannot:

  • Older Windows versions (Windows 10 without the paid codec)
  • Most web platforms and CMS uploads (WordPress, Shopify, social media)
  • Many photo editing applications
  • Email clients that display inline image previews
  • Printing services that accept only JPG or PNG

If you have already dealt with a single HEIC file, you know the drill. But when you are facing dozens or hundreds of them, you need a batch solution. If you need a refresher on single-file conversion, see our guide to converting HEIC to JPG.

Step-by-Step: Batch Converting HEIC Files Online

Our converter tools support multiple file selections, making batch conversion straightforward:

Converting to JPG (Best for Photos)

  1. Open the HEIC to JPG Converter.
  2. Click the upload area or drag and drop your HEIC files. You can select multiple files at once from your file browser.
  3. The tool processes each file in your browser — nothing is uploaded to a server.
  4. Download the converted JPG files individually or all at once.

Converting to PNG (Best for Graphics with Transparency Needs)

  1. Open the HEIC to PNG Converter.
  2. Select or drag your HEIC files into the upload area.
  3. Wait for the browser-based conversion to complete.
  4. Download your PNG files.

Converting to WebP (Best for Web Use)

If the converted images are destined for a website, consider converting directly to WebP for the best combination of quality and file size. Use our HEIC to WebP Converter for this workflow.

JPG vs. PNG: Which Should You Choose?

When batch converting, you need to pick a target format. Here is a quick decision framework:

  • Choose JPG if the photos are standard photographs (landscapes, portraits, events). JPG files are smaller and universally compatible.
  • Choose PNG if you need lossless quality or the images contain text, screenshots, or graphics with sharp edges. PNG files are larger but preserve every detail.
  • Choose WebP if the images will be used on websites. WebP offers JPG-level file sizes with PNG-level quality.

For most people batch-converting iPhone photos, JPG is the right choice.

Tips for Organizing Converted Photos

Batch conversions can get messy without a plan. Follow these practices to stay organized:

  • Create a dedicated output folder before you start. Name it something clear like Photos_JPG_March2026.
  • Keep the originals until you have verified the conversions look correct. HEIC files are smaller than JPGs, so storing them temporarily costs very little space.
  • Maintain the original file names — our tools preserve the base name and only change the extension, making it easy to match originals to conversions.
  • Sort by date after conversion. Most photo managers and file explorers can sort by the date taken metadata, which is preserved in the converted files.
  • Batch rename if needed — if you are uploading to a platform with naming conventions, rename the files in bulk using your OS file manager before uploading.

Storage Savings and File Size Expectations

When converting from HEIC to JPG, your files will generally get larger because JPG is a less efficient format. Here is what to expect:

  • A typical 3 MB HEIC photo becomes a 5–8 MB JPG at high quality.
  • PNG conversions will be even larger — often 10–20 MB per photo.
  • WebP conversions stay close to the original HEIC size, sometimes even smaller.

If storage is a concern after conversion, run the JPG or PNG files through our Image Compressor to reduce their size without visible quality loss. You can compress images in bulk, keeping the total storage impact manageable even with large photo libraries.

Common Batch Conversion Issues and Fixes

  • Conversion seems slow — large batches process in your browser, so speed depends on your device. Close other heavy tabs to free up memory.
  • Colors look slightly different — HEIC supports wide color gamuts (Display P3). JPG uses sRGB by default, so subtle color shifts in vibrant photos are normal.
  • File is not recognized as HEIC — some iPhones save files with the .heif extension. Our tools handle both .heic and .heif files.
  • Live Photos — the converter extracts the still image from Live Photos. The video component is not included in the conversion.

Start Your Batch Conversion

Stop converting HEIC files one at a time. Use our free, browser-based tools to handle your entire photo library in minutes:

All conversions happen locally in your browser, so your photos stay private and secure.
