JPG vs WebP
JPG. JPG (JPEG) uses lossy compression tuned for photographs. Files are small, but it has no transparency and quality drops slightly each time a JPG is re-saved.

Frequently asked questions
Is WebP better than JPG?
For the web, usually yes: smaller files at equal quality, plus optional transparency. JPG is still more universally supported outside browsers.
My WebP is larger than the JPG. Why?
If the JPG was already heavily compressed, re-encoding at a high quality setting can increase size. Lower the quality slider and compare.
Are my files uploaded?
No. This tool reads and processes files directly in your web browser. Nothing is sent to Expensico's servers, and the data is discarded when you close or reload the page.
