Compare HEIC Photos Online
Your iPhone shoots HEIC, your browser can't open it — this tool converts and compares in one step, locally.
100% free · No sign-up · Runs in your browser
Compare HEIC photos now →iPhones save photos as HEIC by default, but Chrome, Firefox and Edge can't display the format — so comparing two iPhone shots on a PC usually means converting them with a separate app first. This tool removes that step: drop HEIC files straight into the grid and they're decoded automatically.
The conversion happens inside your browser using WebAssembly — your photos are never uploaded to a server. Once loaded, every comparison feature works as usual: side-by-side zones with synchronized zoom, pixel diff, curtain slider and A/B flash.
It's the quick way to pick the keeper from a burst of iPhone shots, or to compare an edited export against the original HEIC.
How to use
- 1Open the tool and drop your .heic files into the zones — no pre-conversion needed.
- 2Wait a moment while each photo is decoded locally (the first file loads the converter).
- 3Compare with synced zoom, pixel diff or A/B flash, like any other image.
Why use this tool
HEIC works in every browser
Chrome, Firefox, Edge, Safari — decoding is handled by the tool, not the browser.
Private, local conversion
HEIC decoding runs in your browser via WebAssembly. Photos never leave your device.
Mix formats freely
Compare a HEIC against a JPEG export, a PNG screenshot — any combination.
Full comparison toolkit
Synced zoom, pixel diff with threshold, curtain slider and A/B flash all work on decoded HEIC photos.
Frequently Asked Questions
Do I need to convert HEIC to JPEG first?
No — that's the point. Drop the .heic file in and the tool converts it automatically before displaying.
Are my photos uploaded for conversion?
No. The converter is a WebAssembly library that runs entirely in your browser; nothing is sent to a server.
Why does the first HEIC take a moment to load?
The converter library (~1 MB) is downloaded on first use only, then decoding is quick. Non-HEIC images are unaffected.
Does Live Photo or HEIC video work?
Only still HEIC/HEIF images are supported. Live Photo motion parts and videos are not.
