Batch Convert HEIC to JPG
Drop in a whole folder of iPhone photos and take back one .zip. No cap on how many, no account, and nothing is uploaded to a server.
Your photos are converted on your own device and never leave it - nothing is uploaded to a server.
Works with files up to ~50 MB each. WebP export isn't available in Safari - the browser itself doesn't support saving it.
How the batch works
Select the whole lot
Drag a folder's contents in, or click Choose files and use Ctrl+A / Cmd+A in the picker. Filenames are preserved, so the order survives.
Let it run
Photos are converted one after another on your own machine. Leave the tab open and watch the list fill in.
Take one .zip
Hit Download all and the entire batch comes back as a single archive - no clicking through hundreds of saves.
Why Windows still can't do this by itself
As of August 2026 there is no built-in way to convert a folder of HEIC photos to JPG on Windows. The Photos app offers "Save as" one file at a time, and that is true even after you have paid $0.99 for the HEVC Video Extensions that let Windows display HEIC at all. The request asking Microsoft's own PowerToys team to add batch HEIC conversion - issue #35796 - has been open and unassigned since November 2024.
macOS is the exception: Finder's Quick Actions convert a whole selection natively. If you are on a Mac you may not need this page at all. On Windows, Android or Linux, batch conversion means either a desktop app or a converter like this one. The Windows guide compares every workaround.
Where the limits actually are
Most online HEIC converters put a number on how many files you may convert. That number is not a technical limit - it is a cost control. Those tools upload your photos and convert them on their servers, so every batch costs them bandwidth and CPU, and the cap is how they keep that bill down. heictojpg.com, the largest of them, allows up to 200 photos per batch and points you at a signup for more (checked August 2026).
A converter that runs inside your browser has no such bill, so it sets no such cap. What it does have is your device's memory. In practice that means a laptop or desktop copes with several hundred photos in one pass, while a phone is more comfortable with a few dozen at a time. If a very large batch stalls, split it and run it twice - the tool is free either way, so there is nothing to gain by pushing one enormous batch through.
| Method | Batch limit | Cost | Uploads your photos |
|---|---|---|---|
| Windows Photos app | 1 file at a time | Free (needs $0.99 codec to view) | No |
| Microsoft PowerToys | Not supported | Free | No |
| heictojpg.com | 200 per batch | Free, signup for more | Yes |
| macOS Finder Quick Actions | Whole selection | Free | No - needs a Mac |
| PhotoAnvil (this page) | Your device's memory | Free | No |
One thing worth saying plainly: converting never touches your originals. Every HEIC you drop in stays exactly where it was, and the JPGs are new files - so a bulk conversion is not a decision you have to be nervous about. If you are weighing up which version to keep long-term, HEIC vs JPG goes through it, and HEIC to PNG covers the lossless option.
Frequently asked questions
How many HEIC files can I convert at once?
There is no limit set by this tool, because there is no server deciding what you are allowed to send. The real ceiling is your own device's memory: a desktop or laptop browser handles several hundred photos in one go, while a phone is happier in batches of a few dozen. If a very large batch stalls, split it in half and run it twice.
Can Windows batch convert HEIC to JPG on its own?
No. The Windows Photos app can only "Save as" one file at a time, even after you buy the $0.99 HEVC Video Extensions. A feature request asking Microsoft's PowerToys team to add batch HEIC conversion has been open and unassigned since November 2024.
Why do other online HEIC converters limit how many files I can upload?
Because they convert on their own servers, so every photo you convert costs them bandwidth and processing. Caps and account prompts are how that cost is controlled - heictojpg.com, for example, allows up to 200 photos per batch and asks you to sign up for more. A converter that runs in your browser has no such cost, so it has no such cap.
Do I get all the converted photos in one download?
Yes. Each photo gets its own download link, and there is a "Download all" button that packages the whole batch into a single .zip file, so you are not clicking through hundreds of individual saves.
Do my filenames stay the same?
Yes. Each converted file keeps its original name with the extension swapped, so IMG_4021.HEIC becomes IMG_4021.jpg. That matters in bulk, because it keeps your photos in the same order as the originals.
Are my photos uploaded when I convert a large batch?
No, and that does not change with batch size. Every photo is decoded and re-encoded by your own browser, on your own device. Nothing is sent to a server at any point, which is also why the size of the batch costs nobody anything.
Will a big batch slow my computer down?
It will use your processor while it runs, in the same way any photo software would. Converting is done file by file, so you can leave the tab working and come back to it. Keep the tab open until the batch finishes - closing it stops the job, since the work is happening locally rather than on a server.
