Batch convert a whole folder of HEIC photos
Drag a folder onto the tray, or select every file at once. Each photo is converted in turn on your device and you get one ZIP at the end. There is no cap on the number of files.

Drag the line to compare the original with the JPEG at the quality you chose. The loupe shows a 3× crop under your pointer.
How to batch convert
- Open the folder of HEIC photos on your computer.
- Drag the folder itself, or select all the files, onto the tray above.
- Wait for each thumbnail to develop. The ledger shows how many are done.
- Click the amber download button; with more than one file it reads Download N JPEGs as ZIP.
How long it takes
It depends on your device, not on an internet connection. On the PC this site was built on, a 12-megapixel photo took about 0.7 seconds and a batch of 120 small files took 25 seconds; your times will differ. The first file also waits for the decoder to load, about 1.5 MB, once. Very large batches are limited by your browser's memory: if you hit trouble, do them in two rounds.
Changing the quality after the fact
Move the quality slider, then click Apply quality to all. Every file is re-converted from the original HEIC, so there is no double compression.
