Convert iPhone HEIC photos to JPG in bulk

Convert iPhone HEIC photos to JPG in bulk, fully offline — drop the folder on 1FileTool's Convert tool and get matching .jpg files in your output folder. The sample ZIP has eight real HEIC files you can practice on.

What you'll need

• 1FileTool installed — the HEIC decoder is built in, so this works without internet
• The sample HEICs below, or your own .heic photos from an iPhone

Good news on this one: a conversion can't overwrite its source — a JPEG can't "replace" a .heic, so 1FileTool always writes new files. Your originals stay exactly where they are.

Steps

1. Open Convert under Image Tools

Open Image Tools › Convert ("Convert one or more images"). The drop zone accepts "JPG, PNG, WebP, HEIC, BMP, GIF, TIFF" — HEIC is input-only, which is exactly what this job needs.

2. Drop the HEIC folder

Drag all eight IMG_400x.HEIC files onto the zone. They appear as rows; the run button reads Run on 8 images.

3. Set Output format to JPEG

In the options card, set Output format to JPEG (the default). PNG and WebP work too if you need them instead.

4. Pick where the JPGs land

Conversions always write new files — the Replace source switch can't apply across formats. The JPGs land in your output folder (~/Documents/1FileTool by default); click Change in the output row if you'd rather send this run somewhere else.

5. Run and collect the JPGs

Press Run on 8 images. Each row gets a done check as it converts; EXIF orientation is baked into the pixels, so rotated shots come out the right way up. Reveal in Finder opens the folder with IMG_4001.jpg … IMG_4008.jpg.

The result

Eight HEIC files in, eight JPGs out — same dimensions, same rotation, universally openable. There is no quality slider on Convert (it encodes JPEG at a fixed high quality); if you also want smaller files, run the results through Image Tools › Compress.

One honest limit: the conversion is one-way. 1FileTool reads HEIC but cannot write it — there is no HEIC option in the Output format picker.

If it didn't work

• A HEIC row was skipped: the decoder could not read it (some apps write unusual HEIF variants). Convert it on the iPhone itself or re-export as JPEG from the source.
• You can't find the JPGs: check ~/Documents/1FileTool — converters always write new files there (or to the folder set with Change); the HEICs are never touched.
• The JPG looks bigger than the HEIC: normal — HEIC compresses more aggressively than JPEG, so converted files usually grow a little.
• Daily limit: 8 files per calendar day on the free plan — this exact tutorial uses one full day of free runs; Pro removes the cap.

Try next

Stripping the location data off photos is the same drop-and-run shape — try Remove GPS and camera data on the converted JPGs.
