Turn heavy PNGs into light JPGs. For photographic images that don't need transparency, the size drop is usually dramatic.
How to use it
- Drop in your PNG files. A whole batch is fine.
- JPG is pre-selected. The recommended quality is right for most uses.
- Check the new sizes and save.
Your files are never uploaded
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
Frequently asked questions
- What happens to transparent areas?
- JPG cannot hold transparency, so they are filled with white. If your image needs it — logos, icons — keep it as PNG.
- How much smaller will it get?
- A PNG holding a photograph usually shrinks a lot. Simple flat-colour graphics compress well as PNG already, so the gap there is smaller.
- Is it free?
- Yes. No account, no payment, no usage limit.
- Are my files uploaded?
- No. Everything happens inside your browser. A page that is already open keeps working even if you go offline.
- How many images at once?
- There is no count limit. Speed depends on your own device, because your computer does the work rather than a server.
