The format

About Image and WebP

WebP is the modern image format for the web: smaller than JPG, with the alpha transparency of PNG, supported by every current browser. Converting your mixed image library to WebP is the single biggest performance win most sites and portfolios can make. This universal converter accepts anything — JPG, PNG, HEIC, AVIF, GIF, BMP, TIFF — detects the actual format, and produces clean WebP output. Because everything runs in your browser, there is no upload latency, no file-size quota, and no risk of your private photos sitting on a server.

The questions

Frequently asked

Which input formats are supported?

JPG, PNG, AVIF, GIF, BMP, TIFF, HEIC and HEIF. We detect each file's actual format from its contents, so even mis-named files are converted correctly.

Will transparency be preserved?

Yes, for inputs that have alpha (PNG, HEIC, some TIFF). WebP natively supports transparency, unlike JPG.

Does it support HEIC from iPhones?

Yes. HEIC/HEIF images are decoded via heic2any first, then re-encoded as WebP — all inside your browser.

How much space will I save?

Depends on the input. JPG → WebP: ~25-35% smaller. PNG → WebP: 50-80% smaller. HEIC → WebP: usually a touch larger (HEIC is itself highly efficient).

Is anything uploaded?

No. All decoding and re-encoding happens locally in your browser — no server, no upload wait, no file retention.

Why would I convert to WebP?

Faster-loading websites, better Lighthouse scores, smaller image libraries. Every modern browser supports WebP, so you lose nothing by adopting it on new projects.
