iPhones save photos as HEIC by default — a format most websites and Windows apps still don't accept. Here's the fastest browser-based fix.
If a website rejects your photo upload with no clear reason, or a HEIC file just shows as a blank icon on someone else's computer, the format is almost always the culprit. Converting to JPG trades a bit of file size for near-universal compatibility.
Open Squeezr and drop in your .HEIC file.
Set Output format to JPG.
Leave quality around 80–85% for a good balance of size and sharpness.
Click Squeeze all and download — the file downloads with a .jpg extension, ready to use anywhere.
Skip the manual math — open Squeezr with this preset already dialed in.
Open Squeezr with JPG preset →HEIC uses a modern, more efficient compression method than JPG, which is why Apple made it the default — but JPG (from 1992) is still the format nearly every system, browser and platform on earth supports out of the box. Since Squeezr's converter runs in your browser rather than on a server, this works entirely offline-capable and privately — no photo of yours is ever transmitted anywhere.
Squeezr accepts multiple files at once — drop in your whole batch of HEIC photos, set the format to JPG, and hit Squeeze all. Each one converts independently, and you can download them all together as a single .zip instead of one at a time.
