When it comes to optimizing images for the web, maintaining quality while reducing file size is crucial. Lossless compression is a method that reduces the size of an image file without sacrificing its original quality. This technique is particularly important for photographers, designers, and anyone who needs to preserve image detail while optimizing file storage or load times. In this article, we’ll explore the best online image converters for lossless compression and provide tips on how to use them effectively.

What is Lossless Compression?

Lossless compression is a process that reduces the file size of an image without removing any data.
