HEIC

HEIC is a modern image format that offers superior compression techniques compared to JPEG, allowing for high-quality images at smaller file sizes. This innovative format supports features like multiple images in a single file and advanced audio-visual capabilities, making it ideal for photography and mobile applications. Utilize HEIC for efficient storage without compromising image quality.

PGM

The Portable Gray Map (PGM) format is a simple, portable image file that represents grayscale images. It is part of the Netpbm format family, suitable for easy manipulation and conversion. PGM files store pixel intensity values in plain text or binary, ensuring broad compatibility across various platforms and applications. Ideal for graphic designers and developers looking for a straightforward approach to grayscale image processing.
