Compress an image on iPhone
iPhone camera photos can exceed 10 MB straight from the camera roll. If you need a smaller file for email, a form upload, or sharing in a group chat, a quality adjustment in the browser is the fastest fix — no app required.

How to compress a photo in Safari on iPhone
Open this page in Safari, tap the image picker and choose a photo from your camera roll, set the quality and tap Compress. The result downloads straight to your Files app.
Will the compressed file look noticeably different?
At Quality 80 a typical camera photo compresses to 20-30 % of its original size with no visible difference on a phone screen. Drop to 70 for even smaller files when appearance is less critical.
