Prepare iPhone photos for editing and annotation
PNG avoids the additional lossy compression used by JPG, making it useful for screenshots, markup, design reviews, and repeated edits.
- Expect PNG files to be larger than JPG or WebP files.
- Use PNG when image fidelity matters more than download size.
- HEIC photos do not gain transparency during conversion; PNG simply supports it in later edits.
What lossless PNG conversion means
PNG stores the rendered pixels without the additional lossy compression used by JPG. It does not recover information already compressed into the HEIC source, but it avoids adding a new lossy stage to an editing workflow.
This makes PNG useful for screenshots, diagrams, annotations, and images that will be saved repeatedly while work is in progress.
Why the PNG may be much larger
Photographs contain complex color variation that PNG cannot compress as efficiently as HEIC or JPG. A larger output is therefore expected and does not indicate that the conversion added visual detail.
Use a single sample to estimate storage needs before converting hundreds of photos, and switch to JPG or WebP when delivery size matters more than lossless 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 PNG (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.
