iPhones save photos as HEIC, and Windows often can't open them without extra codecs — leaving you with files you can't view, edit or upload. The good news: you can convert HEIC to JPG on Windows without installing any software at all, right in your browser.
Why Windows struggles with HEIC
HEIC is Apple's space-saving format. Windows can sometimes open it if you install Microsoft's HEIF/HEVC codecs, but those aren't there by default — so a HEIC file shows a blank thumbnail or an "unsupported format" error. Converting to JPG removes the problem entirely, because JPG opens on every PC.
Convert HEIC to JPG in your browser
Open HEIC to JPG in any browser on your Windows PC, drag in your .heic photos (you can do several at once), and download standard JPGs. There's nothing to install, no account, and nothing is uploaded — the conversion happens locally on your machine.
Need a PDF instead?
If you photographed documents on an iPhone and need to upload them, convert straight to PDF with HEIC to PDF — it combines several HEIC photos into one document. For other formats, the image converter handles PNG, JPG and WebP.
Stop the problem at the source
To avoid HEIC files in future, change the iPhone setting: Settings → Camera → Formats → Most Compatible. New photos will then save as JPG, which open on Windows natively. Existing HEIC photos still need converting once.
