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.
How to Use This HEIC Converter
This tool converts iPhone HEIC (and HEIF) photos into more compatible formats like JPG, PNG, WebP, or a single multi-page PDF. The conversion runs locally in your browser, so you can process private images without uploading them to a server.
- Add photos: Drag and drop your files into the drop zone above, or click Add Photos.
- Choose an output format: Pick JPG (or switch to another option) before you start a new batch.
- Download: When your queue shows Ready, use Download All. Image outputs download as a ZIP, and PDF output downloads as one multi-page PDF.
What Is a HEIC File?
HEIC is the file extension Apple uses for photos saved in the High Efficiency Image File Format (HEIF). It is designed to keep image quality high while using less storage than older formats. That is why iPhone photos often look great but arrive as files that some computers, apps, and websites do not recognize.
Why HEIC Photos Do Not Open Everywhere
HEIC support depends on the device and the software you are using. Some Windows PCs need additional codecs, some Android apps only accept JPG or PNG, and many web portals (including document and listing sites) reject HEIC uploads entirely. Converting to a universal format like JPG (or to PNG for lossless workflows) avoids the "file type not supported" dead end.
HEIC vs JPG vs PNG vs WebP (Quick Reference)
If you are unsure which format to choose, use this quick guide. A good rule of thumb is: pick JPG for compatibility, PNG for lossless exports and transparency, WebP for smaller web images, and PDFwhen you need a single file for receipts, scans, or multi-photo submissions.
| Format | Best for | Pros | Tradeoffs |
|---|---|---|---|
| HEIC | iPhone storage | Small files, modern compression | Not accepted by many apps and websites |
| JPG | Maximum compatibility | Works almost everywhere | Lossy compression, no transparency |
| PNG | Editing and transparency | Lossless, supports alpha | Larger file sizes |
| WebP | Web performance | Great quality at smaller sizes | Some older tools do not support it |
| Multi-photo submissions | One file for many pages | Not ideal for photo editing |
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.
