HEIC to JPG Converter
iPhones save photos as HEIC, a format many websites, forms and older programs cannot open. This tool converts HEIC and HEIF photos to JPG or PNG inside your browser, one or many at a time, and the photos stay on your device. Built for New Zealand users, with nothing sent to a server.

How do I convert a HEIC photo to JPG?
Choose the HEIC photos, pick JPG or PNG and a quality, and download each converted file. The conversion runs in your browser using an open-source decoder, so the photos are not uploaded. JPG at 90% quality keeps the photo looking the same while working everywhere, while PNG is lossless but much larger.
Why HEIC photos will not open
HEIC is a modern format that uses video compression (HEVC) to keep photos small. Apple devices read it natively, but many other systems need extra software or a licence to open it. Websites that accept uploads often limit files to JPG and PNG, which is why a photo from an iPhone is sometimes rejected.
Converting to JPG fixes that for almost any use.
Settings on the iPhone
If you would rather your iPhone saved JPG in the first place, change Camera formats to Most Compatible in Settings. Photos then use more space but need no conversion. Sharing a photo through some apps and the Mail app can also convert it automatically, depending on the options chosen.
To resize or compress the converted photo, use the compress image tool.
How this is calculated
The rule, step by step, so you can check any figure by hand.
the HEIC file is decoded to raw pixels by the open-source decoderthe pixels are re-encoded as JPG at your quality setting, or as PNGPNG is lossless; JPG throws away detail the eye is least likely to noticeeach converted photo has its own download link
HEIC (High Efficiency Image Format) stores a photo at roughly half the size of a JPG of similar quality, which is why iPhones use it. The cost is compatibility: many websites, older versions of Windows, some printers and many forms accept only JPG or PNG.
Converting is a decode and re-encode. JPG at 90% looks the same to most eyes, but each re-save loses a little, so keep the original HEIC as the master. The converter does not carry over every piece of metadata, such as depth maps and Live Photo video, and the colour handling of wide-gamut photos may differ slightly.
A worked example
A 12-megapixel iPhone photo of about 2 MB as HEIC, converted to JPG at 90%.
- Original (HEIC)about 2 MB
- Converted (JPG, 90%)often 3 to 5 MB
- Pixelsunchanged
- Upload to the webno

Privacy
Your photos are decoded by your browser and never sent to a server, which matters for personal photos and for images of other people covered by the Privacy Act 2020. You can disconnect from the internet after the page loads and the converter will still work.
What it leaves out
Live Photo video, depth data and some metadata are not carried over, and a very large batch can use a lot of memory on a phone. HEIC files with several images give one output file for each image.
What this calculator does not do
- HEIC and HEIF photos only
- Up to 40 photos at a time
- Live Photo video and depth data not kept
- Memory use can be high for very large photos
Common questions
Is my photo uploaded?
No. It is converted in your browser.
Is the quality the same as the original?
JPG at 90% looks very close to the original; PNG is lossless.
Can I convert many photos at once?
Yes, up to 40.
Why is the JPG bigger than the HEIC?
HEIC compresses more efficiently, so the same picture needs more space as a JPG.
Does it keep the date and location?
Some metadata may not carry over, so check before you rely on it.
