HEIC to PNG Converter
Turn iPhone HEIC files into PNG for transparent overlays, annotation tools, and pixel-perfect editing on desktop.
Photo conversion stays on your device. Speed and batch capacity depend on the files, browser and available memory.

At most three files are processed at once. Large images can still exceed your browser's available memory.

Export to JPG, PNG, WebP, or combine scans into one multi-page PDF.
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.
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.
