Choose PNG when you need a lossless copy, a transparent background, or crisp text, screenshots, and graphics. For ordinary photos you want to share or upload, HEIC to JPG gives a much smaller file.
PNG is lossless and uncompressed compared with HEIC, so the same photo takes more space. That is the trade-off for perfect quality. If size matters, use JPG instead.
Yes. HEIC is decoded in your browser with a WebAssembly HEIF decoder, so Chrome, Edge, and Firefox on Windows can convert it — no codec pack and no upload.
No. Conversion runs entirely on your device; your original photo never leaves the browser.
PNG supports transparency, but standard iPhone HEIC photos are fully opaque, so there is no transparency to preserve. PNG is most useful here for its lossless quality.
PNG is useful when you need a lossless image for editing, screenshots, design workflows, or apps that reject HEIC but also recompress JPG. This converter reads your HEIC or HEIF photo in the browser and exports a PNG file without uploading the original image.
If you only need the smallest universal photo format, HEIC to JPG is usually the better choice. PNG is lossless, but it can be much larger than both HEIC and JPG, especially for real-world camera photos.
HEIC decoding depends on your browser and operating system. Safari and Apple devices usually handle HEIC best; some Windows and Chrome setups need HEIF/HEVC support before a HEIC file can be decoded. For the technical background, read the HEIC / HEIF format guide.
