How to batch convert HEIC photos to JPG in Chrome

To batch convert HEIC photos to JPG, choose the output format, try a small sample, and then add the rest of your files in manageable groups. Download the converted images and compare them with the originals before clearing your source folder.

A batch is convenient, but a completed download is only part of the job. You still need to know whether every intended photo converted and whether the copies work in the app where you will use them.

Prepare the files and a sample

Put the original HEIC or HEIF photos in a source folder and choose a separate place for the JPG copies. Count the files you intend to convert. If the folder also contains videos or other formats, leave those out of the HEIC batch.

Pick a few representative photos for the first run: a portrait, a detailed scene and any image whose orientation or capture date matters. These are suggested checks, not a claim about a completed product test.

Open Convert HEIC to JPG in Chrome. Review JPG and the quality setting before adding the sample. The store description says adding files can start conversion automatically.

Convert the collection in groups

1. Save and inspect the sample JPG files.
2. Add the next group with Add files, or drag the supported photos into the extension.
3. Let the group finish and note any unsuccessful conversions.
4. Download the successful results separately or collect them in a ZIP.
5. Continue with the remaining groups, keeping a note of which originals each group contains.

The product page specifies up to 200 supported files per batch and 100 MB per file. Those are product limits, not a promise that every computer will process the largest possible group comfortably. If a large batch stalls, try fewer files before repeating the whole collection.

Check the downloaded files against the originals

Extract a ZIP before using its images in another app. Compare the downloaded file count with the number of successful conversions, then compare that count with your original selection.

A ZIP of successful results may leave out a file that failed. A matching count is useful, but also check the filenames so an accidental duplicate does not hide a missing photo.

Check	What to do if it differs
Number of intended photos and saved JPGs	Identify the missing originals and retry them separately
Orientation and visible detail	Compare the copy with its HEIC original before changing settings
Capture date or location information	Inspect the converted file's metadata; keep the original when that information matters
Acceptance by the destination app	Try one saved JPG there before uploading the entire collection

For a single rejected upload, use the HEIC upload troubleshooting guide. This batch workflow focuses on completeness across a collection.

Keep quality and metadata separate

JPG uses lossy compression. A high quality setting can reduce visible compression damage, but it does not make the conversion lossless. Inspect detail at a useful zoom level rather than judging only the small preview.

The product page warns that EXIF information may not transfer completely and that conversion produces a standard still image. Do not use the JPG batch as your only archive of Live Photos or other HEIC-specific content.

For a format decision, see JPG or PNG for HEIC conversion. Whichever output you choose, keep the originals until you have checked the collection and the destination app.
