Convert a folder in manageable batches

Batch HEIC Converter

Add multiple iPhone photos, monitor each file in the queue, and download image results together as a ZIP or combine them into a PDF.

Photo conversion stays on your device. Speed and batch capacity depend on the files, browser and available memory.

Privacy First

All decoding runs in your browser with no uploads, no account, and no cloud queue.

Smart Queue

At most three files are processed at once. Large images can still exceed your browser's available memory.

Built for Compatibility

Export to JPG, PNG, WebP, or combine scans into one multi-page PDF.

Plan a reliable batch conversion

Large photo sets use significant memory. The converter limits concurrent work, reports each file separately, and lets successful files finish even if one source is unreadable.

  • Choose the output format before adding a new batch.
  • Split very large libraries into smaller groups and verify each download before continuing.
  • For PDF output, add files in the order the pages should appear.

JPG, PNG, WebP, or PDF for a batch?

Choose JPG for a broadly compatible photo folder, PNG when repeated editing matters more than file size, and WebP for images destined for a modern website. Choose PDF only when the photos belong in one ordered document.

Changing formats does not improve the detail in the source. It changes compatibility, compression, and how the resulting files are packaged.

How to handle a failed file inside a batch

A single failure often indicates a partial cloud download, damaged transfer, or unsupported HEIC feature. Finish the successful files, then retry the failed image by itself after exporting a fresh original.

  • Do not rename another file format to .heic; changing an extension does not change its contents.
  • Avoid closing the tab until the ZIP or PDF download has completed.

Check the output, not just the download

Each completed preview now reports dimensions, input/output bytes and measured conversion time. Download the local conversion report to compare files without sending the report to this site. PDF timing covers image preparation, not final document assembly. Use the conversion verification checklist for metadata, quality and browser limitations.

Frequently Asked Questions

Is this HEIC conversion private?
Yes. Conversion happens on your device inside your browser. Your images are not uploaded to a server as part of the conversion process.
Do you store my photos or keep a copy?
No. The app reads your selected files, generates converted downloads, and shows previews using temporary browser URLs. When you refresh or clear the queue, those previews are released.
Can I combine multiple HEIC photos into one PDF?
Yes. Choose PDF as the output format, add your images, then click Download Multi-Page PDF once they are ready.
Will converting HEIC to JPG reduce quality?
JPG uses lossy compression. For most everyday photos it looks great, but if you need maximum fidelity choose PNG (larger files) or keep the original HEIC as your archive.
Why did a file fail to convert?
Some files are corrupted, partially downloaded, or use features certain decoders do not support. Try again with a single file, export the original photo again from your device, or convert to a different output format.

Tips to Avoid HEIC Issues (iPhone & Windows)

If you want to stop creating HEIC files going forward, iPhone has a camera setting for that. Open Settings > Camera > Formats, then select Most Compatible to save new photos as JPG. If you already have a library of HEIC images, converting them to JPG or PNG is the fastest way to make them usable in older desktop apps, email attachments, and upload forms.
