Frequently asked questions
- Does this tool upload my image?
- No. File validation, image decoding, compression, and download preparation all happen locally in your browser.
- Which image types can I compress?
- This tool accepts PNG, JPEG, and WebP files with valid image data, then creates a WebP output file.
- Why can the output be larger than the source?
- A source image may already be efficiently compressed, or WebP encoding at the selected quality may need more bytes. The size comparison reports this honestly.
