How to Convert HEIC to PNG Online (Free & Lossless)
PNG is the format you want when quality matters: screenshots, design assets, archive copies, or any image you plan to edit later. Apple's HEIC saves space on your iPhone, but most editors and tools still expect PNG. This guide shows you the fastest way to convert HEIC to PNG online — without uploading anything, without losing a single pixel, and without paying.
Why convert HEIC to PNG instead of JPG?
JPG always re-compresses your photo, which slowly degrades quality every time you save it. PNG is lossless — every pixel decoded from the HEIC file is preserved exactly. That makes PNG the right choice when you want to crop, edit, retouch, or archive an iPhone photo without quality loss. The trade-off is file size: a 2 MB HEIC will typically become a 6–10 MB PNG, because lossless compression simply can't shrink photographic data as aggressively.
Convert HEIC to PNG in 3 steps
1) Open heictoall.net in any modern browser. 2) Drag and drop one or more .heic files onto the converter — or tap to pick them from your iPhone. 3) Choose PNG as the output and download. That's it. The whole job runs locally in your browser using WebAssembly, so your photos never travel to a server. For batches, all PNGs are bundled into a single ZIP archive.
Is online HEIC to PNG conversion safe?
Most so-called "online" converters upload your photos to their servers, keep them for hours or days, and may train AI models on them. heictoall.net is different: everything happens client-side, in your own browser. No file ever leaves your device. There's no account required for the free tier, no email harvesting, and the source code paths that handle your files are transparent. If you're processing personal photos, IDs, medical scans, or anything sensitive, in-browser conversion is the only safe option.
PNG vs HEIC: when to use which
Keep the original HEIC when you only need to view photos on Apple devices and want to save iCloud space. Convert to PNG when you need to edit, print at high quality, paste into Word or Google Docs, archive originals, or hand off to a designer. Convert to JPG when you only need a small, shareable copy. WebP is a good middle ground for the web. You can always convert HEIC to PNG later — but converting JPG back to PNG won't recover lost quality.

FAQ
Is PNG really lossless from HEIC?
Yes. The decoder reads the full pixel data from the HEIC container and re-encodes it as PNG without any quality loss.
Why is my PNG so much bigger than the HEIC?
HEIC uses HEVC compression (very efficient, slightly lossy). PNG uses lossless compression, so photographic data typically grows 3–5×.
Can I convert HEIC to PNG on my iPhone?
Yes. Open Safari or Chrome on iOS, go to heictoall.net, and pick the HEIC files from your camera roll. Everything runs locally on your phone.
Does it support Live Photos?
The still image is extracted and converted to PNG. The motion video component cannot be preserved in a PNG file.
Is there a file size limit?
Practical limits depend on your device's RAM, not on us. Most phones handle 50+ MB HEIC files without issue.
