Preview before you convert

Private HEIC Viewer

Add HEIC or HEIF files to see local previews, confirm each photo is readable, and download a compatible copy when needed.

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.

Check HEIC photos without sending them to a server

The preview cards above are created from files selected on this device. Use them to identify photos, check orientation, and spot incomplete transfers before exporting.

  • Add a small batch first when you are reviewing a large photo library.
  • A preview does not replace the original file; keep the HEIC source as your archive.
  • If a photo cannot be decoded, transfer the original from the iPhone again rather than relying on a thumbnail.

Viewer or converter: which do you need?

Use the viewer when you only need to identify a photo or confirm that a transfer completed. Download a JPG copy when another person, website, or desktop program must open the image.

HEIC viewing support varies by operating system and installed software. A browser-based preview is useful on shared or managed computers where installing a codec is not practical.

What the preview can and cannot verify

The preview confirms that the browser decoder can read the image data. It does not verify every item of embedded metadata, edits stored by Apple Photos, or auxiliary image data such as depth information.

  • Compare important images with the original in Apple Photos before deleting anything.
  • Use the converted copy for sharing and retain the source file for future editing.

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.
