What happens to PNG transparency when converted to JPEG?

Because JPEG does not support alpha transparency, transparent areas are rendered on a solid white background.

Can I convert HEIC photos from an iPhone?

Only if your browser can open HEIC files, which Safari on Mac and iOS can. In other browsers, export the photo as JPG from your phone first.

Will converting change my image size in pixels?

No. Only the file format changes; width and height stay the same.

Which format gives the smallest file?

Usually WebP, then JPG. PNG is the largest for photos but best for sharp graphics and text.

Is my image uploaded?

No. Conversion happens in your browser.

Which format to choose

JPG is the most compatible format for photos and gives small files, but it does not support transparency. PNG is lossless and supports transparency, which suits logos, screenshots, and graphics with text. WebP supports both transparency and strong compression, and works in every modern browser.

Converting a photo from PNG to JPG or WebP usually makes it much smaller. Converting a JPG to PNG makes the file bigger without improving quality, because detail lost in the original JPG cannot be recovered.

Transparency and colors

When a transparent PNG or WebP is converted to JPG, transparent areas become white, since JPG cannot store transparency. Keep PNG or WebP if the image sits on a colored background.

Animated GIF and WebP files are converted using their first frame only.
