HEIC to PNG converter

PNG is the format to choose when an iPhone photo has to survive repeated editing, or when a tool specifically demands a PNG. This converter decodes your HEIC files and re-saves them as lossless PNGs entirely on your own device — nothing is uploaded, and after a one-time decoder download it even works offline.

  • No upload — files stay on your device
  • Works offline once loaded
  • Free forever, no signup, no watermark

From a free tool to your own software

Software for image-heavy websites and online stores

Online stores, publishers and listing sites receive images in every format, from iPhone HEIC files to oversized PNG exports, and someone ends up converting and compressing them batch by batch. When that step gets skipped, pages load slowly and photos look inconsistent. An image pipeline inside your own system converts, compresses and sizes every upload automatically.

  • Automated image pipelines

    Uploads are converted to WebP or AVIF, compressed and generated in every size your templates need, with the original kept safely for later use.

  • Product catalogue back offices

    Your team uploads supplier photos in any format and gets consistent, compressed catalogue images ready for your own store and marketplace listings.

  • Field photo capture apps

    Mobile apps for inspectors, sales reps or delivery staff that convert HEIC photos and shrink them on the phone, so uploads still go through on weak networks.

  • Website speed rebuilds

    We rework slow sites so images are served in modern formats at the right size for each screen, which helps page speed and the experience on mobile data.

Who we build this for: E-commerce brands, publishers, property and listing portals, and any team uploading large volumes of photos.

This tool runs entirely in your browser. The team that built it designs custom software for businesses and runs DigiSign, our own signage platform, in production.

How to use this tool

  1. Add your HEIC photos

    Drop up to 25 iPhone photos onto the box or tap to choose them — they are read directly on your device, never uploaded.

  2. Let the decoder load once

    The first photo downloads the HEIC decoder (about 1 MB) a single time; every conversion after that runs locally in about a second.

  3. Download your PNGs

    Save the converted files one by one or all together. Expect them to be noticeably larger than the originals — that is the price of a lossless format.

Questions people ask

When should I pick PNG instead of JPG for an iPhone photo?

Pick PNG when the image will be edited and re-saved repeatedly (PNG never degrades), or when software insists on a PNG. For sharing, emailing and uploading, JPG is the better choice — it is far smaller and every service accepts it.

Why is the PNG so much bigger than my HEIC file?

HEIC is the most space-efficient photo format in common use and PNG is lossless, so a 2 MB HEIC photo can easily become a 20 MB PNG. Nothing is wrong — that is what storing every pixel exactly costs. If the size surprises you, the HEIC to JPG converter gives files close to the original size.

Does the conversion happen on my device?

Yes, entirely. The photo is decoded with the open-source libheif library running as WebAssembly in your browser and re-encoded to PNG by the browser itself. There is no upload endpoint on this site — the first conversion just downloads the decoder once (about 1 MB), then everything works offline.

Will I lose quality converting HEIC to PNG?

No — PNG is lossless, so every pixel the HEIC decoder produces is stored exactly. What you cannot get back is any detail the iPhone discarded when it first compressed the photo, but nothing further is lost in this conversion.

Why do Windows and my editing software refuse HEIC?

HEIC uses the HEVC video codec, which carries patent licensing costs, so Microsoft and many software vendors never bundled a decoder. Converting to PNG (or JPG) turns the photo into a format every program has read for decades.
