Turn your JPG images into HEIC right in the browser — this tool will shrink each file and hand it back in seconds, with nothing uploaded to any server. JPEG is the universal lossy photo format, tuned to shrink photographs by discarding detail the eye barely notices. HEIC is Apple's high-efficiency format, storing iPhone photos at roughly half the size of JPEG with better quality. HEIC adds an alpha channel, so you gain transparency support that JPG never had. Free, private, unlimited, and watermark-free.

Add your JPG files
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.

Why convert JPG to HEIC?
The main reason is iPhone photos, where it saves storage dramatically over JPEG. JPG excels at photographs and camera images, but when you need transparency, HEIC is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
Converting into HEIC re-encodes the image, and because HEIC is lossy you control the trade-off with the quality setting. At high quality the difference is invisible.
A note on file size

Tips & Things to Know
Check the file size after converting
Expect the HEIC file to be noticeably smaller than your JPG. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Add transparency support
Because HEIC supports an alpha channel, the result can hold transparency even though JPG itself is always fully opaque. Areas stay on whatever background the JPG shows.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your JPG files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
Tune the quality if you need to
For HEIC you can trade a little detail for a smaller file using the quality slider. At around 90% the difference is invisible to the eye, while the file can be much smaller — useful for web images and email attachments.
