JPG to HEIC Converter — Free Online
Processed on our servers — auto-deleted within 1 hour, never used for anything else.
iPhone and newer Apple devices save photos as HEIC because it stores the same image in roughly half the space of JPG. Convert your JPG shots to HEIC here to save storage or match an upload requirement — our servers handle the HEIC encoding that browsers cannot do yet, then delete both files right after processing — or let them auto-delete within the hour.

Save the HEIC file with one click. Delete upload and output right after processing, or let them auto-delete within the hour.
About this tool
Converting JPG to HEIC
A JPG file jpg trades detail for small files with lossy compression, and carries no transparency. HEIC heic is the iphone's native photo format — roughly half the size of jpg at equal quality, with limited support outside apple ecosystems.. Converting moves your image from the first set of trade-offs to the second: file size shifts with the format's compression style, transparency survives where supported, and pixel data is re-mapped to the target format exactly.
What to check after converting
Open the result and check the two things conversion can change: transparency and size. Transparency is carried over exactly where the target format supports it. HEIC compresses lossily, so this conversion re-encodes your image — reasonable settings keep the difference invisible, extreme ones do not. Remember the source was already lossy: converting to HEIC preserves what arrived, it cannot restore what earlier compression discarded. Your original file stays untouched on your device either way, and the download is a brand-new file.
Frequently asked questions
Will converting to HEIC improve the quality?
No conversion improves quality that compression already removed — moving JPG to HEIC preserves what arrived and stops further loss, but the artifacts baked into the source stay baked in. The gains are about features: transparency, compatibility, or editing headroom.
Is my image uploaded anywhere?
No — the conversion runs entirely in your browser. The image is processed on your device and never sent to any server, which you can verify by disconnecting after the page loads.
Why convert JPG to HEIC instead of the other way around?
The direction follows what the destination needs: Apple device storage efficiency versus photos and web uploads. Converting back is always available — but each lossy hop re-encodes the image, so keep the highest-quality format as your working copy and convert toward the destination.
Why does this conversion run on a server?
Browsers cannot encode HEIC natively — the encoding happens on our servers instead. Both files are deleted automatically within one hour, or delete them yourself with one click right after the conversion.
