FAQ
Image converter questions
Can I convert PNG to JPG?
Yes. Upload the PNG, select JPG and choose a background colour. Transparent areas will be flattened because JPG does not support transparency.
Can I convert JPG to PNG?
Yes. The image can be saved as PNG, but converting JPG to PNG will not restore quality already lost through JPG compression.
Will converting an image reduce its file size?
Not always. WebP and lower JPG quality may reduce size, while PNG files can be larger.
Are my images uploaded?
No. Conversion happens locally inside the browser.
Does JPG support transparent backgrounds?
No. Transparent areas must be replaced with a solid background colour.
Does the converter resize my image?
No. The converter should preserve the original pixel dimensions.
Which format should I use?
Use JPG for photographs, PNG for transparency and lossless graphics, and WebP for efficient web images.
