To convert HEIC to PNG online, add your iPhone or iPad photos above, press Convert and download the PNG files. PNG is lossless, but files are much larger than HEIC or JPG. Conversion runs in your browser; your photos are never uploaded.
Convert HEIC photos to lossless PNG files for editing and archiving. PNG opens in every program and preserves every pixel of the decoded photo. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online converters, this tool does not upload your images. Your browser decodes each HEIC file, converts it and creates the PNG file on your own device. That keeps private photos private, avoids upload waits and keeps working on a slow connection once the page has loaded. You can convert up to 50 files at a time and download them one by one or together as a ZIP.
Working with HEIC files more often? Our HEIC to JPG Converter Online is another quick option. You may also like the JPG to PNG Converter Online, or browse every tool in the Websolindia image converter collection. Optimised images help page speed, which you can measure with our Website Performance Analyzer.
This table compares the two formats so you can decide whether converting is the right move.
| Feature | HEIC | PNG |
|---|---|---|
| Full name | HEIC (HEIF image with HEVC compression) | PNG (Portable Network Graphics) |
| Origin | iPhone default photo format since iOS 11 (2017) | W3C Recommendation in 1996 |
| Compression | Lossy (lossless modes exist) | Lossless |
| Transparency | Yes | Yes, full alpha (256 levels of transparency) |
| Animation | Image sequences possible | No (animated PNG is a separate extension) |
| Colour depth | 8 and 10 bits; wide colour | Up to 16 bits per channel |
| Typical file size | Much smaller than a comparable JPG | Large for photos, small for flat graphics |
| Best for | Photos taken on iPhone and iPad | Logos, screenshots, graphics and anything needing transparency |
| Browser support | Safari and Apple devices; limited elsewhere | Every browser, app and device |
| File extension | .heic, .heif | .png |
File size: PNG is much larger than HEIC; expect files many times the size for photographs.
This is exactly what happens to your file. Nothing is hidden, and you can verify that nothing is uploaded by watching your browser's network tab while you convert.
| Step | What happens |
|---|---|
| 1. Read the file locally | Your browser reads the file from your device into memory. Nothing is sent to a server. |
| 2. Identify the format | We check the file's first bytes (its signature) instead of trusting the extension, so a PNG renamed to .jpg is still handled correctly. |
| 3. Decode the HEIC to pixels | The image is decoded to raw red, green, blue and alpha pixels using libheif, the open-source HEIF decoder, compiled to WebAssembly and run inside your browser. |
| 4. Resize (optional) | If you set a maximum width, larger images are scaled down with an area-weighted filter. Images are never enlarged, and the proportions are always kept. |
| 5. Keep transparency | Transparency passes straight into the PNG file, because PNG supports it. |
| 6. Encode the PNG | The pixels are written out as PNG using your browser's PNG encoder (lossless). Metadata such as camera details and location is not copied. |
| 7. Report the result | We show the dimensions, the sizes before and after, and the change: (new size − original size) ÷ original size × 100. For example, 500 KB becoming 350 KB is −30%. |
| Setting | Default | Range | What it does |
|---|---|---|---|
| Maximum width | None | 1–20,000 px | Scales larger images down. Never enlarges. |
| What | Formula | Notes |
|---|---|---|
| Size change | (new − original) ÷ original × 100 | Shown for every file. Negative means smaller. |
| Downscale factor | min(1, maximum width ÷ width) | Applied only when you set a maximum width; never above 1. |
Speed depends on your device and the image size. In our Chrome tests on a desktop-class processor, a 6-megapixel photograph took about 2 seconds to convert to WebP or PNG. AVIF is the slowest: about 2.5 seconds on Fast and about 7.5 seconds on Balanced. Phones and older laptops take longer, and images over about 120 megapixels are declined rather than risking a frozen browser.
| Format | Where it opens | Typical use |
|---|---|---|
| HEIC | Safari and Apple devices; limited elsewhere | Photos taken on iPhone and iPad |
| PNG | Every browser, app and device | Logos, screenshots, graphics and anything needing transparency |
| This converter | Current Chrome, Edge, Firefox and Safari. Needs JavaScript and WebAssembly | Private conversion on your own device |
HEIC is among the most efficient photo formats, while PNG stores every pixel without lossy compression. For smaller files use the HEIC to JPG Converter Online.
The conversion adds no loss: PNG stores the decoded pixels exactly. HEIC itself is usually lossy, and that earlier loss remains.
Yes. The HEIC is decoded in your browser and never uploaded.
Wide-colour photos are converted to standard sRGB at 8 bits per channel, so some very saturated colours are slightly toned down.
Yes, when the HEIC has an alpha channel, which is uncommon for camera photos.
JPG, because it is far smaller. Use PNG when you need lossless editing or transparency.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. You can convert up to 50 HEIC files in one go. It is provided by Websolindia.
No. Your HEIC files are read and converted inside your browser, on your own device. They are never sent to Websolindia or anyone else, which is why this converter is safe for private photos and documents.
Yes. The new file is created from the decoded pixels, so camera details, GPS location and other embedded metadata are not copied. If you need to keep metadata, use a desktop editor.
Up to 50 files per batch and 150 MB per file. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari. It also needs WebAssembly, which all of those browsers include.
