Convert HEIC to WebP — Free, Fast & Private
For photos headed to a website, HEIC to WebP is one encode instead of two. Everything runs in your browser — nothing is uploaded.
Skip the JPEG middle step
Going HEIC to JPG to WebP runs the picture through two lossy encoders. Converting straight to WebP uses one. For email, print or forms that demand JPEG, use HEIC to JPG; for lossless output, HEIC to PNG; for the smallest file where you control the fallback, HEIC to AVIF. Other sources follow the same route through the WebP converter.
What an iPhone HEIC holds
A HEIC can contain the main photo, a Portrait depth map, HDR gain data and, for Live Photos, a video track. The WebP contains the photo only, and the output is 8-bit.
Location removed, orientation kept
EXIF such as GPS, timestamps and device model is not written to the WebP. The rotation is applied to the pixels first, so photos taken sideways stay upright.
Check the WebP against the HEIC before you save
The result card shows the HEIC size, the WebP size and the output dimensions, with a before and after slider. The WebP can be smaller or larger than the HEIC depending on the photo and the preset; the card shows the actual change. Batches download as a ZIP.
Choosing Smart or Gentle
Smart is the default and favours a small file. Gentle uses a higher quality for photos you plan to edit or print. The measured table below uses real HEIC photographs.
If HEIC will not open
Why HEIC will not open on Windows covers the causes. MiniPx decodes HEIC itself, so no codec install is needed.

Measured 2026-10-07 in Chromium 145.0.7632.6 by running this page's converter with its default setting (WebP) on each file. The photos and scans are CC0 or public-domain files from Wikimedia Commons; the HEICs are made by pillow-heif (libheif with the x265 encoder) at quality 50 from the named file, not shot on an iPhone. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).
