Your iPhone saves photos as HEIC, but your website needs them in a web-optimized format. WebP files are 30-50% smaller than JPG with the same visual quality, and they support transparency. Converting HEIC directly to WebP skips the JPG middleman and gives you the best format for web performance.
| File type | HEIC | WebP | Note |
|---|---|---|---|
| iPhone 15 Pro photo (48MP) | 5.2 MB | 4.8 MB | 8% smaller |
| iPhone 14 photo (12MP) | 2.4 MB | 2.1 MB | 12% smaller |
| iPhone screenshot | 0.8 MB | 0.3 MB | 62% smaller |
| Landscape photo (12MP) | 3.1 MB | 2.6 MB | 16% smaller |
Skip the HEIC → JPG → WebP chain. Convert directly from HEIC to WebP for the fastest possible website images with excellent quality.
iPhone product shots in HEIC can go straight to WebP for your Shopify, WooCommerce, or custom store. Smaller images mean faster product pages.
Photographers and creators can batch convert iPhone galleries to WebP for online portfolios that load fast and look sharp.
Content creators who shoot on iPhone can convert HEIC to WebP for web-based content management systems and headless CMS platforms.

Open Picmal, drag your HEIC files or folders into the window, select WebP as the output format, adjust quality if needed, and click Convert. Picmal handles everything locally.
WebP files are 25-35% smaller than JPG at the same quality, and WebP supports transparency. If your images are destined for the web, WebP gives you better performance than JPG. Only use JPG if you need compatibility with very old systems.
WebP uses lossy compression by default, so there's some quality trade-off for smaller files. At 85-95% quality, the difference from the original HEIC is invisible. Picmal also supports lossless WebP if you need zero quality loss.
WebP and HEIC have similar compression efficiency, so file sizes are comparable. The advantage of WebP is browser compatibility — HEIC isn't supported by any web browser, while WebP works everywhere.
