FAQ
Frequently asked questions
Is my image uploaded anywhere when I convert it?
No. Conversion happens locally using the Canvas API in your browser. The image never leaves your device.
Why convert JPG to PNG?
PNG is lossless and supports transparency, which is useful when you need to further edit the image without compounding compression artifacts — even though the JPG source itself has no transparency to preserve.
Will the file size increase?
Usually yes. PNG is lossless, so it's typically larger than an equivalent JPG, especially for photos.
Is there any quality loss in this conversion?
No additional loss is introduced by the conversion itself, though any compression already present in the original JPG can't be undone.
