FAQ

Are my images uploaded?
No. Conversion uses the Canvas API entirely in your browser.
Which formats are supported?
Input: common image formats (JPG, PNG, WebP, GIF). Output: JPG, PNG, or WebP.
When should I use WebP?
WebP often produces smaller files than JPG or PNG at similar quality — ideal for websites and apps.
Will transparency be preserved?
PNG and WebP support transparency. Converting to JPG fills transparent areas with white.
Need to reduce file size instead?
Use the Image Compressor tool to resize and lower quality without changing format.
