HEIC TO PNG
From HEIC/HEIF to a lossless PNG file
The local libheif library decodes the image; PNG then stores the pixels losslessly.
Confirm PNG
PNG is preset as the output format and does not need a quality slider.
Save the PNG
Download results individually or collect multiple files in a ZIP archive.
FORMAT KNOWLEDGE
What happens when HEIC/HEIF becomes PNG?
LokalPix loads libheif locally and decodes the image in your browser. The result is then stored losslessly as PNG.
HEIC/HEIF
iPhone default format since iOS 11
HEIC uses the HEVC video codec for still images and achieves smaller files than JPG at comparable quality. HEIF is the container standard; HEIC is the Apple-specific variant.
PNG
Lossless output with broad compatibility
PNG stores the decoded pixels without further loss and is supported almost everywhere — in image editors, documents, and upload forms.
IMPORTANT
No quality recovery
PNG cannot recover detail removed by HEVC compression. Conversion only changes the file format of the existing pixels.
FORMAT IN DEPTH
HEIC/HEIF and PNG compared
Technical background on decoding and format choice.
How HEIC/HEIF encodes
HEIC uses the HEVC codec (H.265) for still images. The HEIF container can store multiple images, depth data, and metadata in one file. Lossy compression achieves smaller files than JPEG.
How LokalPix decodes
LokalPix downloads libheif as a WebAssembly bundle locally. The HEIC image is decoded entirely in your browser; no pixel content leaves your device.
Why PNG is useful
PNG is more broadly compatible than HEIC and is accepted by most applications and upload forms. It preserves all visible image content losslessly.
What is lost?
Earlier HEVC losses remain; PNG cannot repair them. HEIC-specific metadata, depth data, and embedded previews are not transferred by default.
FREQUENT QUESTIONS
Questions about HEIC and HEIF to PNG
Answers about quality, privacy, and format limitations.
Is HEIC decoded locally in the browser?
Yes. LokalPix downloads libheif locally and decodes the image exclusively in your browser. There is no image upload.
Does PNG improve the quality of the HEIC image?
No. PNG stores the pixels decoded from the HEIC losslessly, but it cannot recover detail removed by HEVC compression.
Why is the PNG file larger?
PNG is lossless and is usually larger than HEIC for photographs. Larger does not automatically mean more image detail.
Are resolution and aspect ratio preserved?
Yes. LokalPix does not intentionally change the pixel dimensions during this conversion.
Are metadata preserved?
Metadata are removed by default. HEIC-specific EXIF and XMP data are not transferred to the PNG file.
Can I convert several HEIC files?
Yes. Up to 20 files can be processed in one batch and downloaded individually or together as a ZIP archive.
PRIVACY BUILT IN
