Files are processed three at a time to avoid memory spikes on high-volume batches.
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.
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.
