Group files first
Put the HEIC files for one task in a dedicated folder so you do not mix originals from different projects.

How to batch convert HEIC files to JPG
Batch conversion is useful when you have a folder of iPhone photos from an event, a product shoot, a shared album, or an iCloud export and need JPG copies together.
Best workflow for multiple HEIC photos
- Put the HEIC files you want to convert in one folder first.
- Select all needed .heic or .heif files in the converter.
- Use JPG quality around 90% for a good everyday balance.
- Wait for every row to show Converted.
- Use Download all as ZIP to keep the JPG copies together.
Prepare a batch before you upload
Remove obvious duplicates
Delete burst shots or accidental screenshots before conversion if you do not need them as JPG.
Check destination rules
Look for accepted file types, maximum file size, image dimensions, and upload count limits.
Test one file
Convert one representative image first when the destination has strict quality or size requirements.
When to split a large batch
Browser-based conversion uses your device memory. If you have a very large folder, split it into smaller groups instead of selecting hundreds of high-resolution files at once. This keeps the page more responsive and makes it easier to retry only the files that need it.
| Batch size | Recommended approach | Why |
|---|---|---|
| 1-10 photos | Convert together in one batch. | Easy to review and download individually or as ZIP. |
| 10-50 photos | Convert together if your browser remains responsive. | Works well for event sets, product photos, and shared folders. |
| 50+ large photos | Split into smaller groups. | Large iPhone photos can put pressure on browser memory and downloads. |
| Mixed source folders | Sort by task before converting. | It is easier to retry, rename, and upload clean groups. |
Keep filenames organized
Converted files keep the original base name and replace the HEIC or HEIF extension with the selected output extension. For example, IMG_1234.HEIC becomes IMG_1234.jpg. If you download a ZIP, the converted files stay together in one archive.
Quality settings for batches
Everyday sharing
Use 85-90% when the JPGs are for email, messages, forms, and general uploads.
Listings and portfolios
Use 90-95% when images need to look sharp on marketplaces or client previews.
Archive copies
Use 95-100% and keep the original HEIC files as the long-term source.
Strict upload limits
Lower quality gradually and test one image first if small text or faces matter.
Troubleshooting batch conversion
| Problem | Likely cause | What to do |
|---|---|---|
| One file fails while others convert. | The file may be damaged, incomplete, or a different format with a HEIC-like name. | Retry that file alone and keep the original for another export attempt. |
| The page feels slow. | The selected batch is too large for the current browser session. | Clear the page, split the folder, and convert smaller groups. |
| ZIP download takes time. | The browser is packaging many output files into one archive. | Wait for the ZIP to finish, or download smaller groups if the batch is very large. |
| Uploaded JPGs are rejected. | The destination may have file-size, dimension, or naming restrictions. | Check the portal rules and adjust quality or filenames before retrying. |
Batch conversion checklist
- Keep the HEIC originals until your upload, client, or recipient accepts the JPG files.
- Use consistent quality across one batch so image appearance and file size are predictable.
- Download as ZIP when you need to move the converted photos to another computer.
- Convert another batch only after the current batch finishes and downloads correctly.
