# HEIC to WebP converter

> WebP is the practical middle ground: nearly as small as HEIC, and it opens everywhere HEIC does not. If the destination is a website, this is usually the conversion you want.

## Why WebP rather than JPG

If you are putting images on a website, JPG is leaving performance on the table. WebP's lossy mode
 typically produces files 25–35% smaller than a JPG of matching visual quality, and it is supported in
 every browser that has shipped since 2020 — Chrome, Edge, Firefox, Safari 14+ and every current mobile
 browser. That is broad enough that most sites now serve WebP as the default rather than the fallback.

Coming from HEIC, WebP is the natural landing spot. Both are modern block-based codecs, so the
 re-encode preserves quality more gracefully than a jump back to a 1992 format.

| Target | Size of a 12 MP photo | Support | Best used for |
|---|---|---|---|
| HEIC (source) | 1.6 MB | Apple only, in practice | Phone storage |
| AVIF | ~1.1 MB | 2021 browsers onward | Sites that can serve fallbacks |
| WebP | ~1.9 MB | 2020 browsers onward | General web use |
| JPG | ~3.4 MB | Everything, forever | Email, printing, uploads |

## Choosing a quality setting

The slider maps to WebP's quality parameter. Some rules of thumb from testing photographic content:

 - **90–100** — visually lossless, but the files stop being competitive with JPG. Rarely worth it.

 - **80–85** — the sweet spot for photographs on the web. This is the default here.

 - **70–79** — fine for thumbnails, gallery grids and anything displayed small.

 - **Below 70** — visible softening in skies, skin and out-of-focus areas. Avoid for hero images.

WebP degrades differently from JPG: instead of the blocky 8×8 artefacts JPG produces, you get a
 smoothing or waxy quality in fine texture. It is less ugly at low bitrates, but it is also easier to
 miss until you look closely.

 **Serving WebP properly.** Do not just swap the file extension in your `<img>`
 tags. Use a `<picture>` element with a WebP source and a JPG fallback, or let your
 CDN negotiate the format. That way ancient browsers and some email clients still get an image
 instead of a broken icon.

## Resize while you convert

Format alone will not save a page that is serving 4032 px photos into a 800 px slot. Cap the longest
 edge with the Size dropdown as you convert — 1600 px covers most full-width use, 2400 px is generous
 for retina displays, and 800 px is right for thumbnails. Combining a resize with WebP at quality 82
 routinely takes a 1.6 MB HEIC down to under 150 KB.

## Frequently asked questions

**Is WebP better than JPG?**

For file size at equivalent quality, clearly yes, typically 25–35% smaller. For universal compatibility, JPG still wins, since a handful of older email clients, print services and desktop applications do not read WebP.

**Do all browsers support WebP?**

Every browser released since 2020 does, including Safari from version 14. The remaining gaps are outside the browser: some email clients, older photo software and a few upload forms still reject it.

**Should I use WebP or AVIF?**

AVIF produces smaller files and is the better format on paper. WebP has slightly broader support and encodes far faster. For a site with a proper picture element and fallbacks, AVIF first is sensible; for a single format everywhere, WebP is the safer pick.

**Can WebP store transparency?**

Yes, both in its lossless and lossy modes, which is one of its advantages over JPG. Transparency in the source HEIC is carried through by the converter above.
