Format comparison
HEIC (High Efficiency Image Container) is a high-efficiency photo format commonly used on iPhone and iPad. It often produces smaller files, but compatibility varies across apps and platforms.
Pros
- ✓ Efficient compression for photos
- ✓ HEIF container features (metadata, sequences)
- ✓ Common default on Apple devices
Cons
- ✗ Compatibility can be limited in some apps/browsers
- ✗ May require extra codecs on some platforms (e.g., Windows)
PNG (Portable Network Graphics) uses lossless compression and supports transparency. Ideal for logos and screenshots.
Pros
- ✓ Lossless compression
- ✓ Alpha transparency
- ✓ Great for sharp edges
Cons
- ✗ Larger file sizes
- ✗ Inefficient for photos
When to Convert HEIC to PNG
Convert HEIC to PNG when you want a lossless format for editing—adding text, compositing, and repeated saves.

Technical details
HEIC/HEIF is commonly used for photos on iPhone and iPad. It can keep file sizes smaller, but compatibility varies across Windows, browsers, and editing tools.
Good for
- On-device photo storage: Efficient photo saving- Keeping metadata: Managing capture info alongside the image
Notes
- Compatibility: You may need JPEG/PNG/WebP for sharing and uploads- Environment differences: Decoding and conversion behavior depends on browser/platform support

PNG Technical Specifications
Technical details
PNG is a lossless raster format that preserves pixel data exactly. It supports alpha transparency, which makes it a common choice for logos and UI assets.
Good for
- Logos/icons: Assets that need transparency- Screenshots: Crisp text and line art
Notes
- Photos: Files can be large (WebP/JPEG may be a better fit)- Quality setting: Since PNG is lossless, “quality” controls may have little or no effect
Reference: W3C: PNG 3rd Edition
How to Use
Add files
Drop or click to select your HEIC files (multiple supported)
Confirm output
Default is PNG. You can change to another supported output format if needed.
Adjust options
Set quality, resize, and metadata options only if you need them.
Convert & download
Download each file, or download everything as a ZIP for batch outputs.
FAQ
Will the file get larger converting HEIC to PNG?
Yes. PNG uses lossless compression, so files are typically 2–5× larger than HEIC. It's best suited for editing where quality preservation matters.
Should I convert to PNG or JPEG?
Choose PNG (lossless) if you'll keep editing, JPEG(smaller) if you're sharing or posting.
Will the output have a transparent background?
HEIC photos typically don't contain transparency data, so the result stays opaque.PNG supports transparency, but only if the source has it.
Will converting reduce image quality?
It depends on the output format. PNG is lossless, so quality stays the same. Lossy formats like JPEG/WebP/AVIF/JXL can change file size and appearance depending on the quality setting. Always verify with the final output before publishing.
Can I keep Exif metadata?
When "Keep Exif/Metadata" is ON, we try to carry over things like capture time, camera info, and GPS where possible. Some tags may be dropped depending on the input, output format, and browser environment. Turn it OFF if you want to remove location data before sharing.
Can I convert multiple files at once?
Yes. You can select multiple files, convert them in one run, and download each file individually. For multiple outputs, you can also download everything as a ZIP. For very large batches, splitting into smaller runs is more stable.
Are my images uploaded to a server?
No. Conversion runs locally in your browser, and your images are not sent to an external server.
What if conversion fails or is slow?
Some formats (like HEIC/HEIF) depend on browser support. If it fails, try another browser, reduce the number of files, or resize before converting.
