Frequently asked questions
Which conversion should I choose for a smaller file?
WebP usually gives the smallest files at the same visual quality, followed by JPG. Use PNG only when you need lossless quality or transparency.
Will transparency be preserved?
PNG and WebP keep transparency. JPG does not support transparency, so transparent areas are filled with white when converting to JPG.
Is there a limit on how many images I can convert?
No fixed limit — conversion runs on your own device, so you can batch-convert dozens of images at once for free.
Do you keep a copy of my images?
No. The site is a static page; conversion happens with the HTML5 canvas API in your browser and no image data is ever transmitted.
