Questions people ask
How do I convert WebP to JPG?
Choose the WebP files, pick JPG under “Convert to”, and tap Convert. Many sites save images as WebP, but forms and older apps often accept only JPG.
Are my images uploaded?
No. Conversion uses your browser’s built-in canvas, on your own device. Nothing is sent anywhere.
Which format should I use?
JPG for photos and form uploads, PNG for screenshots, logos and anything with sharp text or transparency, WebP for websites where you want the smallest files.
Why did my PNG get a white background?
JPG does not support transparency, so transparent areas are filled with white. Convert to PNG or WebP to keep transparency.
Can I convert HEIC photos from an iPhone?
Only in Safari, which can open HEIC. Other browsers cannot read HEIC. On an iPhone you can also set Settings → Camera → Formats → Most Compatible so new photos are saved as JPG.
