Frequently asked questions
Does converting JPG to PNG improve quality?
No. A JPG has already lost some detail, and PNG cannot bring it back. What PNG does is stop any further loss when you edit and re-save, and it supports transparency for later editing.
Why is the PNG so much larger?
PNG stores every pixel without lossy compression, so photographs produce large files. Use JPG or WebP if file size matters more than editing flexibility.
Will the PNG have a transparent background?
No. JPG has no transparency, so the PNG is fully opaque. You can add transparency later in an image editor.
Are my images uploaded?
No. Conversion happens in your browser and your images never leave your device.
