How to compress images online without losing quality | Img2Web
Reduce JPG, PNG and WebP file sizes by balancing visual quality, resolution and format.
What compression actually changes
Compression reduces the data needed to represent an image. A good result makes the file smaller without visible blocks, blur or lost detail.
Quality, dimensions and format work together. Resize an oversized photo before compressing it.
A practical workflow
Keep only the dimensions needed for the final use and begin with quality between 75% and 85%. Compare the result at full size.
Use JPG or WebP for photographs.
Use PNG when transparency or crisp edges matter.
Avoid repeatedly compressing the same output.
How to check quality
Inspect faces, small text, gradients and detailed areas. Raise quality slightly if you notice halos or patches.
