Perkforge
How it works
Choose or drop a PNG, set the output quality and convert it locally. Compare both file sizes before downloading. Nothing is uploaded and no account is required.
Useful to know
WebP supports transparency. Lower quality produces smaller files but may introduce visible compression, especially around sharp edges and text.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
