Convert Apple HEIC photos into lossless PNG images, right in your browser. Nothing is uploaded.
HEIC is the default photo format on modern iPhones and iPads, prized by Apple for fitting high quality into a small file. The catch is that many places outside Apple's world cannot read it, from Windows machines to older editors and upload forms. Converting to PNG turns those photos into a lossless, widely supported image that opens almost everywhere and never re-compresses the picture.
To use it, load one or more HEIC files from your device and each is decoded and saved as a PNG you can download. The original HEIC is untouched, so you keep both if you like. Because PNG is lossless, the converted image holds every pixel of detail the decoder produced, with no quality traded away in the save.
The trade-off to understand is size. PNG never throws detail away, which is great for fidelity but means a photograph saved as PNG can be several times larger than the same shot as JPG. For graphics, screenshots, or images you plan to edit further, that lossless quality is worth it. For a plain photo you just want to share, JPG will be far lighter.
Pick PNG over JPG when you need an exact, lossless copy or when transparency matters, such as an image you will layer in a design tool. If the goal is simply to open an iPhone photo on a Windows PC or upload it somewhere, and file size is a concern, JPG is usually the smarter target. Choose based on whether fidelity or lightness matters more.
Common uses include bringing iPhone photos into design software that expects PNG, keeping a lossless master before editing, converting a screenshot-style HEIC where crisp edges matter, and handing images to a system that only accepts PNG or JPG.
Everything runs locally in your browser through the device's own decoder, so no photo is ever uploaded. There is no account and no charge, and the only real limit is your device's memory, which surfaces only with very large files or big batches. Personal images stay entirely on your machine.
PNG is lossless, so it preserves every pixel and supports transparency, which suits editing and graphics work. JPG is smaller but discards a little detail each save and has no transparency. For ordinary sharing JPG is lighter, but for a faithful master PNG is better.
HEIC uses modern compression that packs photos into small files, while PNG stores everything losslessly, which takes far more space for a detailed photograph. The larger size is the cost of keeping every pixel. If size matters more than fidelity, convert to JPG instead.
PNG fully supports transparency, but a normal HEIC photo has none to begin with, so the result is a solid rectangular image. Transparency only appears if the source image already had it. The format is capable of it either way.
Most EXIF metadata, including GPS coordinates, is generally not preserved in the converted PNG. That protects your location when you share the image. Keep the original HEIC if you need those details later.
Yes, you can load several at once and download each converted PNG. Because PNGs are large and the work is local, a big batch uses more memory, so very large sets may be slower on older devices. Most computers handle a full album comfortably.
No, PNG is lossless, so no detail is thrown away in the save itself. The result matches what the HEIC decoder produced. Any earlier compression in the original HEIC is simply carried through, not worsened.
