Frequently asked questions

How do I convert HEIC to WebP on Mac?

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.

Why convert HEIC to WebP instead of JPG?

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.

Does converting HEIC to WebP lose quality?

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.

How much smaller are WebP files compared to HEIC?

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.

Can I batch convert my entire iPhone photo library to WebP?

Yes. Export your HEIC photos from Apple Photos, drag the folder into Picmal, and convert them all to WebP at once. Process thousands of photos in minutes.
