Convert HEIC to PNG Online — Lossless & Free
Get perfect quality PNG files from your iPhone photos. All processing happens in your browser — nothing gets uploaded.
How to Convert HEIC to PNG
Converting HEIC to PNG preserves full image quality with no compression artifacts. Here's how to do it in three steps — no software needed.
- 1
Add your HEIC files
Drag and drop your HEIC photos into the converter above, or click to browse your files. You can select multiple images for batch conversion.
- 2
Automatic lossless conversion
Each HEIC file is decoded and re-encoded as a PNG file directly in your browser. PNG uses lossless compression, so your converted images retain every pixel of detail from the original.

Download your PNG files
Click download next to each file, or use 'Download All as ZIP' for batch results. Your PNG files are ready for editing, printing, or archival.
Why Convert HEIC to PNG Instead of JPG?
PNG uses lossless compression, meaning your converted image retains every pixel of detail from the original HEIC file. JPG, by contrast, uses lossy compression that introduces subtle artifacts — fine for sharing, but not ideal when quality matters most.
Choose PNG over JPG when you plan to edit the image further in Photoshop, GIMP, or another editor. Each time you save a JPG, it recompresses and loses a tiny bit more quality. PNG avoids this problem entirely since it never discards image data.
PNG also supports transparency (alpha channels). If your HEIC file contains transparency data — common in screenshots, stickers, or composited images — converting to PNG preserves it. JPG cannot store transparency and fills transparent areas with a solid color, usually white.
The trade-off is file size. A PNG file is typically 3-5x larger than an equivalent JPG. For web use, social media sharing, or email attachments where file size matters, JPG is usually the better choice. For editing, archival, and situations requiring transparency, PNG is superior.
PNG vs JPG — Which Should You Choose?
The choice between PNG and JPG depends on what you plan to do with the converted image.
| Use Case | Best Format | Why |
|---|---|---|
| Further editing in Photoshop/GIMP | PNG | Lossless — no quality degradation on re-save |
| Sharing via email or messaging | JPG | Smaller file size, universal compatibility |
| Uploading to social media | JPG | Platforms recompress anyway, smaller upload |
| Printing photos | PNG or JPG | PNG for highest quality, JPG for convenience |
| Web design / UI elements | PNG | Supports transparency, crisp edges on graphics |
| Archival / long-term storage | PNG | No quality loss over repeated opens and saves |
| Screenshots with text | PNG | Preserves sharp text edges without JPG artifacts |
| Product photography | PNG | Background removal requires transparency support |
As a rule of thumb: use PNG when quality and editability matter most, use JPG when file size and compatibility are the priority. When in doubt, convert to both and compare.
Your Files Stay Private
Every conversion happens locally in your browser using WebAssembly. Your HEIC photos are never uploaded to any server. No account required, no data stored, no tracking of your files.
Close the tab and all processed data is gone. Your photos remain entirely under your control.
Technical Details
This converter decodes HEIC files using libheif compiled to WebAssembly, renders the pixel data to an HTML5 Canvas element, and exports as PNG using the Canvas API. The entire process runs in your browser with no server interaction.
PNG files produced by this converter use maximum compression (deflate level 9) to minimize file size without any quality loss. Color depth from the original HEIC file is preserved at 8-bit per channel (24-bit RGB or 32-bit RGBA with transparency).
EXIF metadata from your original HEIC file — including camera settings, date taken, and location — can optionally be preserved in the PNG output. By default, metadata is preserved.
