Most upload forms and CMS platforms now prefer WebP over JPG because it renders the same photo in a noticeably smaller file. Filemorph converts a JPG to WebP on your iPhone in a tap, with no upload and no size limit.
Image-heavy websites load faster when photos ship as WebP instead of JPG, and plenty of CMS platforms, ad networks and upload forms now ask for it outright. If you shoot on an iPhone and need a batch of product or blog photos ready for the web, converting on the device that took them saves a round trip through a laptop.
Filemorph re-encodes the JPG using Apple's ImageIO WebP encoder, typically landing 25 to 35% smaller than the source JPG at a comparable visual quality. The conversion is lossy, matching how WebP is normally used for photos on the web, and the output keeps the original color profile and orientation.
In the app: Convert → To WebP.
WebP was built for the web: it compresses photos smaller than JPG at the same visual quality, which means faster page loads and lower bandwidth bills. Use it for website images, product photos and anything you are uploading to a modern CMS; keep JPG for platforms that still reject WebP, like some email clients.

Typically 25 to 35% smaller at a visual quality most people cannot tell apart from the original JPG. Busy, detailed photos compress less than smooth ones.
Every modern browser and most current apps support WebP. A few older tools and some email clients still expect JPG or PNG, so keep the original if you are unsure where the file is going.
