WebP preserves transparent pixels. Maximum quality minimizes further loss, but browser encoders do not guarantee mathematically lossless WebP.

About HEIC to WebP

If an iPhone photo is destined for a web page, WebP is the sensible landing point and going via JPG is a detour that costs quality. Both HEIC and WebP are modern lossy formats built on video-codec techniques, so converting between them is one generation of loss rather than the two you incur by making a JPG first and converting that. WebP also keeps the file substantially smaller than JPG at comparable quality, which is the entire reason to bother when the image will be downloaded by visitors. The catch is reach: WebP is decoded by every current browser but is not a general interchange format, so it is the right answer for a website and the wrong one for sending a photo to someone who will open it in whatever their computer came with.

Shape and export choices

The HEIC is decoded by a WebAssembly decoder, fetched only when a file is chosen so the page stays light for everyone else.
The container is HEIF and the compression is HEVC, neither of which browsers read natively. The decoder resolves both and returns pixels.
The phone's orientation flag is applied while decoding, so a photo shot in landscape is not delivered on its side.
Pixels are re-encoded as lossy WebP at a high quality setting, at the original dimensions. Nothing is resized.
Camera metadata, including any GPS coordinates, is left behind rather than written into the output.

Good fits for HEIC to WebP

Photos from a phone going onto a website

Convert directly to WebP rather than exporting JPG first. Resize to the display width before converting and the two savings compound.

A gallery where page weight matters

WebP across a set of images noticeably reduces total transfer. Serve a JPG fallback through a picture element if any of your traffic is on very old clients.

Check the image before download

This is lossy to lossy, so a second generation of compression is applied. It is still one fewer than converting to JPG and then to WebP, which is the common alternative.
The saving over JPG is real but modest on photographs, typically a fifth to a third. Resizing the image to the width it will actually display saves far more than the format change does.
WebP is a delivery format. Some desktop software and a few upload portals still refuse it, so use JPG when you do not control the destination.
Live Photos contribute their still frame only; the paired video is a separate file and is not read.
There is no way back to HEIC in a browser, so keep the original if it is your only copy.

Questions about HEIC to WebP

Why not convert to JPG and then to WebP?

Because that is two rounds of lossy compression instead of one. Going straight to WebP keeps more of the original detail at the same file size.

How much smaller is WebP than JPG?

Usually twenty to thirty-five percent at comparable quality on photographs. The exact figure depends on the image, and both byte counts are shown.

Will everyone be able to open it?

Every current browser will. Some desktop applications and upload forms still will not, so choose JPG when the file is being handed to a person rather than served by a site.

Is the photo resized?

No. The conversion changes the encoding only. Use the resize tool first if the image is larger than it needs to be.

Does the file leave this device?

No. Decoding and encoding both happen in this tab, and no request carries the photo anywhere.
