Are my photos stored on any server?

No. The HEIC decoding and the JPG writing happen in your browser’s memory.

Why does the first photo take a bit longer?

When the browser cannot open HEIC on its own, the app loads its own decoder.

JPG uses lossy compression. At 90% quality the difference is usually imperceptible; raise it to 100% if you want the maximum.

Select the HEIC or HEIF photos (up to 50 at a time) or drag them onto the dashed area.
Adjust the Quality if you like (90% is enough for most photos).
Click Convert all. Large photos may take a few seconds each.
Download them one by one or use Download ZIP to get them all at once.

Company and government portals often reject HEIC; JPG gets through any of them.

Without installing a video extension or extra program, you convert and open them on the computer right away.

It avoids the “I can’t open this photo” when sending an album to family or clients.

You can convert several photos at once: the app downloads everything in a ZIP.
After converting, the file comes out without the original photo’s data (date, camera and location), which also helps you share with more privacy.
If you need transparency or lossless quality, convert to PNG instead of JPG.

Photos above 40 megapixels or with more than 16,384 pixels per side are rejected.
Original color profiles and HDR are not preserved in the JPG.
Each queue accepts up to 50 photos and 200 MB; beyond that, convert in batches.
