HEIC to JPG in Bulk: Where Free Batches Stop

What limits a HEIC to JPG batch

Each photo sent to a hosted tool is an upload, so the number of photos a tool accepts at once decides how far a job gets. The limit shows up with a folder of photos, not with a single file, and a tool that does not print its number gives no warning before it stops.

heictojpg.com states its number in the page title: up to 200 photos, free. Anyone who learns that figure only partway through a folder has to split the rest by hand and upload again. A converter that decodes the files on your own machine has no upload to ration at all.

For what the format itself is and how it compares with JPG, see What is a HEIC file? How it compares with JPG. The same page covers why iPhone photos arrive in HEIC at all.

Free HEIC to JPG converters compared by batch cap

Only heictojpg prints a photo count on its free page, while Convertio states none and the sakuttoAI converter sets none. The comparison covers heictojpg, Convertio and the sakuttoAI tool.

How many photos each route takes in one go

Tool	Photos per batch	Files kept afterward
heictojpg (free web)	Up to 200	Not stated
Convertio	Not stated	Originals deleted at once, JPGs within 24 hours
sakuttoAI	No cap	Nothing leaves the browser

A blank in the second column is a missing number, not proof that no limit exists. Convertio's page leaves the question open, so sending a large folder there is a test rather than a plan.

heictojpg caps the free web batch at 200

The page title promises up to 200 photos, and a line further down the same page offers the desktop product for bigger jobs. That line advertises batch conversion and compression of 500+ photos at once in a desktop program you download.

For a folder under 200 photos, the free web page is enough. Past that count, the download is the next thing the page offers.

Convertio deletes originals at once but states no batch count

Convertio names two deletion windows: uploaded HEIC photos are deleted immediately after conversion, and JPG results are purged from servers within 24 hours. The originals are the files that hold the private content, and those are the ones the page says it removes right away.

The same page says basic conversions are completely free. It prints no photo count per job, so the size of a batch it will accept is unknown until the upload hits it.

Convert HEIC files in the browser with no batch cap

The sakuttoAI tool decodes every photo on your own machine and returns one ZIP, so nothing is uploaded and the tool sets no photo count of its own. The limit that remains is the memory of the device, which depends on the computer and not on a pricing page.

A photo that never leaves the machine also needs no deletion policy. That settles the privacy question for a folder of family pictures in advance.

The tool needs a free account, and a free account gets 3 tasks a day across all file tools (as of October 2026). Check the current allowance on the tool page before planning a very large job. To turn a whole folder of iPhone photos into JPGs in one ZIP without uploading them, try the free HEIC to JPG converter.

Which route fits a bulk HEIC to JPG job?

The photo count and the kind of photos together point to one tool. A folder under 200 pictures with no private content fits any of the three, and the list shows where each case goes.

• Under 200 photos and nothing private: heictojpg's free web page or Convertio.
• Over 200 photos: the sakuttoAI converter, in one run. The heictojpg free page stops at 200, and Convertio prints no number to plan around.
• Private photos at any count: the sakuttoAI converter, since no photo is uploaded.

Splitting 800 photos into runs of 200 makes 4 uploads, 4 waits and a folder split by hand. A tool with no per-batch number handles the same 800 photos as 1 job.

Summary: count the photos first, then decide where they go

The two facts that decide a bulk HEIC to JPG job are how many photos a tool takes at once and whether the files leave your machine. The free web page at heictojpg takes up to 200 photos, Convertio states no count, and the sakuttoAI converter sets none and uploads nothing. Vendor limits can change, so confirm the current page of a hosted tool before starting a large folder.
