PNG stands for portable network graphics. It is the raster graphics format associated with the .png filename extension. Unlike GIF format, the limitation of 256 colors does not hold with the PNG format. In fact this among other reasons was the motivation behind development of the PNG format to improve upon the GIF format. The PNG format however uses a single image format and thus does not support animations. Because the format was engineered to ease the distribution of graphic files across computer networks it is also not well suited for professional graphics.
HEIC (High-Efficiency Image Container) file format stores images and image sequences. This file format was developed by the Moving Picture Experts Group (MPEG) and it uses High-Efficiency Video Coding (HEVC) compression. HEIC files are known for storing high-quality images with a smaller file size as compared to other image formats, for example, JPEG.
FreeFileConvert uses tuned encoding for PNG to HEIC conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PNG files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized HEIC results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent HEIC audio with dependable progress tracking.
The PNG formation become a published ISO standard in 2004 as ISO/IEC 15948, although it was formally accepted for use by the internet engineering steering group in 1996. The PNG format has broad support for various color palettes including 24 bit RGB, 32 RGBA, and grayscale with optional support for transparency. The lossless data compression method used by PNG is DEFLATE.
The HEIC (High-Efficiency Image Container) file format is a complex image container format based on the HEVC (High-Efficiency Video Coding) compression. HEIC format's capabilities make it a versatile format for storing high-quality images, however, its adoption depends on compatibility with various software and platforms. Users may need to convert the files to more universally supported formats like PNG when sharing or viewing images on devices.
Upload your image file in the PNG format from your device, Dropbox, or Google Drive.
Select HEIC as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
