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.
Why convert HEIC to WebP instead of JPG?
WebP files are 25-35% smaller than JPG at the same quality. 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?
Not by much. HEIC is already an efficient format, so photos come out a little smaller or about the same: 8-16% smaller in the examples on this page. The reason to convert is browser support. Most browsers can't show HEIC, while WebP works in all of them.
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.
