The canvas is filled with the chosen color, the PNG is drawn on top, and the browser encodes JPEG. Non-PNG files are refused so WebP or JPEG is not silently re-encoded here.
Errores habituales
- A JPEG was selected Use this page for PNG only. Use WebP to JPG or Image Compressor for other formats.
- Halos appear around edges Those pixels were partly transparent. Pick a background closer to the surrounding color.
- The file grew JPEG quality is high by default. Lower quality in a compressor if you need a smaller file.
Limitaciones
Animated PNG is not preserved as animation. Color profiles are not copied as a separate workflow. The 15 MB and 8000 pixel limits apply.
Privacidad
The file stays in your browser. PepsTools does not upload it, store it, or send it to another service. Clear the tool or leave the page to drop it from memory.
Preguntas
