A practical format guide
HEIC vs HEIF
HEIF names the container format; HEIC is a common file extension used for HEIF images encoded with HEVC. Both can encounter the same compatibility problems.

Built for Compatibility
Export to JPG, PNG, WebP, or combine scans into one multi-page PDF.
Choose an output based on the destination, not the source extension
Whether a file ends in .heic or .heif, the receiving app determines which replacement format is appropriate. JPG is the usual compatibility choice; PNG, WebP, and PDF serve different workflows.
- Do not fix compatibility by changing .heic to .jpg in the filename.
- Use JPG for general sharing, PNG for editing, WebP for web delivery, and PDF for grouped documents.
- Keep the source container when you may need Apple-specific image data later.
Why the names are often used interchangeably
HEIF stands for High Efficiency Image File Format and describes a container capable of holding images and related data. HEIC is widely used as the extension for HEIF content encoded with High Efficiency Video Coding.
For everyday troubleshooting, the important question is not which acronym appears in the filename. It is whether the destination can decode the file and which output it accepts.
Renaming is not conversion
A file extension is a label. Renaming photo.heic to photo.jpg leaves the original encoded data unchanged, so software expecting JPEG data can still reject it. A real conversion decodes the source pixels and writes a new file in the selected format.
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.
