HEIC to JPG

The HEIC conversion tax: what converting costs you in storage

Converting a HEIC photo to something older does not just change the container, it inflates the file. We measured it: the same photo as JPG is roughly twice the size, and as PNG it is nearly five times the size. That is the price of compatibility, and it is worth knowing before you convert a library of thousands.

Converting a HEIC photo to JPG roughly doubles its file size, and converting it to PNG makes it about 4.7 times larger.

How to use HEIC to JPG

What the tool does, how to run it, and what to expect from the result.

How to convert HEIC to JPG

Converting HEIC to JPG with this tool takes three steps. Select the HEIC or HEIF photo from your iPhone or computer, the tool decodes it in your browser, and you preview the result. Choose a JPG quality preset, then download the JPG to use anywhere that expects a standard image.

Everything happens client-side in your browser. The HEIC file is never uploaded to a server, so the conversion works even on slow connections and keeps the original photo private on your device. The downloaded JPG is a fresh file, leaving your original HEIC untouched.

  • Select one HEIC or HEIF photo
  • Preview the decoded image in the browser
  • Choose a JPG quality preset
  • Download the converted JPG

Why convert iPhone HEIC photos to JPG

HEIC is Apple's default photo format on iPhone because it saves space at high quality, but many websites, web forms, marketplaces, older apps, and Windows tools still expect JPG. Converting to JPG removes that compatibility friction so a photo uploads and displays the first time.

People searching for HEIC conversion usually have a specific destination in mind: a job application form, an insurance upload, a selling platform, or an email attachment. This page is built for exactly that, turning an iPhone photo into a JPG that just works without installing software.

Tips

Getting a better result out of HEIC to JPG

Specific settings and thresholds, not general advice.

  • Converting HEIC to JPG makes the file BIGGER, not smaller. Our own benchmark measured a quality-matched JPG at about 2x the size of the iPhone HEIC it came from, and a PNG at 4.7x, for no visible quality gain. Convert for compatibility, never to save space.
  • The presets are Balanced (quality 86), Smaller file (76) and Higher fidelity (92). Balanced is the right default: at 92 you are paying a real size premium for a difference almost nobody can see.
  • If you only need the photo to open somewhere, Smaller file at 76 is usually indistinguishable on a phone screen and lands closest to the original HEIC size.
  • Do not convert to PNG unless you actually need lossless. Our benchmark put the PNG at 4.7x the HEIC, which is the worst of both worlds for a photograph: enormous and no better looking.
  • Keep the HEIC. Once you have the JPG for whatever refused the HEIC, the original is still the smaller, higher-quality master, and re-converting from it later is always cleaner than converting the JPG again.
Limits

What HEIC to JPG does not do

The honest boundary, so you do not lose time finding it yourself.

  • It does not make the file smaller. A HEIC is already more efficient than a JPG at the same quality; converting costs size, it does not save it.
  • It does not improve the photo. The conversion is lossy-to-lossy, so it can only lose a little.
  • It does not preserve Live Photo motion, depth data, or the HDR gain map. Those are HEIC container features that a JPG has nowhere to store.
  • It converts one image at a time.

It stores images at roughly half the size of JPEG at the same quality and can hold extras like depth maps and Live Photos — which is why switching to JPEG enlarges a library.GeneraliOSFiles & formatsJPEGJPEG (.jpg) is the most widely supported photo format. It uses lossy compression to shrink photographs dramatically, trading a small amount of detail for much smaller files. It has no transparency and is larger than newer formats like HEIC or WebP at the same quality.General

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is this HEIC to JPG converter free?

Yes. This HEIC to JPG converter is completely free with no sign-up, watermark, or limits on how often you convert.

Does it upload my HEIC photo to a server?

No. The HEIC file is decoded, previewed, and exported to JPG entirely in your browser, so the photo stays private on your device and is never uploaded.

What is the difference between HEIC and HEIF?

HEIF is the underlying image container and HEIC is Apple's HEVC-encoded version of it used on iPhone. This tool handles both and exports a standard JPG.

Can it convert many HEIC files at once?

No. This version is single-image by design to keep the in-browser workflow fast and predictable. Convert one photo at a time.

Does it work on iPhone and Android?

Yes. The converter runs in a mobile or desktop browser, so you can convert a HEIC photo directly on your phone without an app.

Does converting HEIC to JPG make the file smaller?

No, the opposite. Our own benchmark measured a quality-matched JPG at roughly 2x the size of the iPhone HEIC it was converted from, and a PNG at 4.7x, with no visible quality gain. HEIC is simply the more efficient format, and converting away from it is a compatibility decision, not a size one.

Why does my iPhone save photos as HEIC?

Because it stores the same image quality in roughly half the space of a JPG. That efficiency is exactly why converting to JPG makes the file bigger, and why the setting exists at all.

Which quality preset should I use?

Balanced, which is quality 86. Higher fidelity (92) costs a real size premium for a difference almost nobody can see on a photograph, and Smaller file (76) is usually indistinguishable on a phone screen.

Should I convert HEIC to PNG instead?

Only if you genuinely need lossless. Our benchmark put the PNG at 4.7x the size of the HEIC, which for a photograph is the worst of both worlds: an enormous file that looks no better.

Does the JPG keep the Live Photo or the depth data?

No. Live Photo motion, depth maps and the HDR gain map are HEIC container features, and a JPG has nowhere to store them. Keep the original HEIC if any of that matters.
