Apple M Series: Top Universal Apps for Silicon Macs
The brand new M1 chip indicates the beginning of creating a rich ecosystem — through universal apps and beyond.
HEIC has been Apple’s default photo format for years now, thanks to its smaller file sizes and solid image quality. But outside the Apple ecosystem, things can still get awkward—especially when you’re sharing photos with Windows users, uploading to older platforms, or simply trying to open a file that refuses to cooperate.
We’ve tested and revisited the current landscape of free HEIC to JPG converters, focusing on tools that are fast, reliable, and don’t overcomplicate a simple task.
If you just want something that works without friction, start here.
HEIC (High Efficiency Image Container) is Apple’s default photo format, introduced with iOS 11.
It’s based on HEIF (High Efficiency Image Format) and uses modern compression technology (similar to HEVC/H.265 for video). The result:
In everyday use, HEIC is simply more efficient than JPEG—which is why Apple adopted it across iPhone, iPad, and Mac. It’s designed for storing more photos without quickly filling up your device.
Despite its advantages, HEIC still runs into compatibility issues outside the Apple ecosystem.
You’ll typically need to change HEIC to JPG when:
JPEG remains the “safe” format—less efficient, but supported almost everywhere.
In practice, most people don’t replace HEIC—they use it for capturing and storing photos, then convert to JPG when it’s time to share or upload.
We keep this simple and practical—because most people converting HEIC files just want something that works without surprises.
For this update, we tested over 10 tools on MacBook Air (M4, macOS Tahoe) and Windows 11 PC (latest updates). These are our top picks that actually work—no more “unsupported format” errors.
If there’s one tool we consistently recommend, it’s iMazing HEIC Converter.

It strikes a rare balance: simple enough for quick conversions, but with just enough control for users who care about output quality and metadata. You can batch convert HEIC to JPG or PNG, adjust JPEG quality, and choose whether to preserve or remove EXIF data.
A subtle advantage: it also converts HEVC (H.265) videos to MP4 (H.264), which makes it more versatile than most “image-only” tools.
It comes from the team behind iMazing — a well-known iPhone manager for file transfer, backups, and device control. If you’re curious how that fits into a broader workflow, we’ve covered it in our iMazing review on TheSweetBits.
Why we like it:
WALTR HEIC Converter leans into simplicity, but with a slightly more polished feel.
In our tests, it handled large batches reliably, and the interface feels slightly more refined than most free utilities. If you regularly export large iPhone photo libraries, this one feels smooth and predictable.

On Windows, CopyTrans HEIC takes a different approach: instead of being a standalone converter, it integrates directly into the system.

Once installed, Windows Explorer can preview HEIC files natively, and you can convert them to JPG via right-click. It’s less about bulk workflows and more about making HEIC feel “normal” on Windows.
Why we like it:
From Sindre Sorhus—known for building focused, high-quality utilities—this HEIC converter is as minimal as it gets.
Drag files in, get JPGs out. That’s it.
There are no extra features, but that’s exactly the point. It feels like a native macOS utility rather than a third-party app.

Why we like it:
If you don’t want to install anything, Pufomi Image Tools offers a browser-based HEIC to JPG converter.
It’s convenient for one-off tasks, especially on shared or restricted machines. But like most online tools, it comes with the usual trade-offs around upload speed and privacy.

Why we like it:
Movavi Video Converter is primarily known for video conversion on macOS and Windows, but it also handles image formats—including HEIC.
It’s not free, but if you already use it (or need a more complete media toolkit), it can replace multiple single-purpose tools.

Apple devices fully support HEIC by default, so everything “just works”. Outside that ecosystem (especially on Windows or older apps), HEIC support isn’t always built in. That’s why Photos may not open, thumbnails don’t appear, and you get format errors. It’s not the file—it’s the lack of support on the receiving device.
These terms are closely related but not interchangeable: HEIF is the container format (like a package), HEIC is Apple’s implementation for images (HEIF + HEVC compression), and HEVC (H.265) is the compression technology inside. A simple way to think about it: HEIF is the format, HEIC is the file you see, and HEVC is how it’s compressed.
Yes—for basic conversions, macOS already has you covered. You can use Preview → open HEIC → File > Export → choose JPEG; Photos app → export images as JPEG, or Quick Actions (Finder) → right-click → Convert Image. These built-in tools are reliable for occasional use. However, they’re limited—there’s no fine control over JPEG quality, no clear option for preserving/removing EXIF metadata, and less efficient for large batch workflows.
Yes—but not always out of the box. Windows typically requires Microsoft HEIF Image Extensions to recognize HEIC files. In many cases, it also needs the HEVC Video Extensions to properly decode and display them. Once installed, you can open HEIC files in the Photos app, and see thumbnails in File Explorer. However, this only solves viewing, not conversion—you’ll still need a dedicated tool for batch processing or quality control.
JPEG is a lossy format, so some compression is unavoidable—but you can minimize quality loss by using high-quality settings (90–100%), avoid repeated conversions, and try to preserve metadata (EXIF) if needed. Tools like iMazing Converter give you control over these settings, which helps maintain visual quality.
Yes—most desktop tools support batch conversion. Apps like iMazing and WALTR let you drag and drop entire folders, and convert dozens or hundreds of images at once. This is much faster than converting images one by one using built-in tools.
They can be—but there are trade-offs. Most reputable tools delete files after processing, but you’re still uploading images to a remote server. That means slower performance for large files and potential privacy concerns. For sensitive or large batches, offline tools are the safer and faster choice.
HEIC is a better format in many ways—but until compatibility fully catches up, conversion is still part of the workflow.
The good news is that this is no longer a painful task. Tools like iMazing and WALTR reduce it to a simple drag-and-drop step, whether you’re handling a single image or an entire photo library.
If we had to suggest a starting point, try iMazing HEIC Converter.
If you care more about workflow feel or batch handling, WALTR is a close second.
And if you need an all-in-one media conversion solution, Movavi Converter is the premium option.
Either way, the goal is the same—make HEIC invisible and keep your photos moving.
