Reduce PNG Size to 51 Kb with pdfFiller
What is a PNG file?
PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. It is widely used for web images due to its ability to maintain high quality while providing transparency options. Unlike JPEG files, PNG files do not lose any data during compression, making them ideal for images with text or sharp edges.
Why is reducing PNG size to 51 Kb essential for document management?
Reducing PNG file sizes is crucial for effective document management. Smaller files facilitate quicker uploads and downloads, optimizing storage space and enhancing collaboration. A file capped at 51 Kb is more manageable for email attachments and ensures faster loading times on websites, which is vital for maintaining user engagement.
