Use PNG when the destination specifically needs PNG output
PNG stores the decoded output with lossless compression. Privacy converts in your browser without uploading the image; Cloud uploads it for server-side processing and deletes uploaded images by default after one day.
Good reason to choose PNG
An editor, design workflow, application, or upload form explicitly requires PNG.
Use JPG instead
The main goal is ordinary photo sharing, broad compatibility, or a smaller output file.
How to Convert HEIC to PNG
Choose one or more HEIC images, convert them to PNG, and check each completed result.
- 1
Choose HEIC images
Choose Privacy or Cloud, then select one or more HEIC or HEIF images. Privacy processes images in the browser; Cloud uploads them for server-side conversion.
- 2
Convert the files to PNG
Processing starts automatically after file selection. Follow the status shown for each image.
- 3
Download and inspect each PNG
Open the completed PNG and check its dimensions, orientation, visual appearance, and file size before deleting the HEIC original.
| Need | Choose PNG | Choose JPG |
|---|---|---|
| Editing workflow | Useful when the editor specifically expects PNG | Useful when the editor accepts ordinary photographic JPG files |
| File size | Often large for photographs | Usually more practical for photographic sharing |
| Compression | Lossless output encoding | Lossy output encoding |
| Transparency | The format supports alpha transparency | The format does not support alpha transparency |
| General uploads | Use when PNG is required | Often the more broadly accepted photo format |
What Lossless PNG Output Actually Means
The converter decodes the HEIC image into pixels and then encodes those pixels as PNG. PNG compression is lossless for the encoded output, but conversion does not recreate information that was previously lost in the source HEIC.
- No JPEG-style re-encoding artifacts: the PNG encoder does not use ordinary JPEG compression.
- Not the original camera data: the PNG contains the decoded image produced from the HEIC source.
- Not guaranteed pixel equivalence: color conversion, bit depth, orientation handling, alpha, and image selection can affect the result.
Why PNG Files Are Often Larger Than HEIC
HEIC is designed for efficient photographic storage. PNG is effective for graphics, screenshots, flat-color artwork, and images that require lossless output, but it is usually less storage-efficient for camera photographs.
- Photographic detail: noise, texture, gradients, and millions of colors can make PNG files large.
- Resolution: more pixels normally produce a larger output.
- Alpha and color information: additional channels or profiles can increase the file size.
- Do not convert only to save space: use JPG or compress the HEIC source when a smaller file is the actual goal.
- Convert HEIC to JPG when ordinary photo compatibility and file size matter more.
- Compress the HEIC file when the destination already supports HEIC.
Transparency, Dimensions, Metadata, and Special HEIC Content
PNG supports transparency, but format support alone does not prove that transparency in a particular HEIC file is preserved by a conversion. The same caution applies to dimensions, orientation, metadata, color information, HDR, depth, thumbnails, and multiple images.
- Transparency: inspect the completed PNG against a contrasting background.
- Dimensions and orientation: check the output pixel size and visible direction.
- Metadata: supported fields are kept by default rather than intentionally stripped, but verify the finished PNG because HEIC-specific fields may not transfer.
- Multi-image HEIC: do not assume that every image or auxiliary layer becomes a separate PNG.
- Live Photos: a static PNG does not reproduce the motion-video portion.
- Learn what a HEIC file can contain before deleting an original.
Convert Multiple HEIC Files and Check Each Result
Both modes accept multiple HEIC or HEIF images. Cloud can also accept one or more ZIP archives mixed with images. Each successful source image produces its own PNG result, while failed items remain identifiable and can be retried.
- Before conversion: choose the mode and check your selection in the file picker; processing begins as soon as you add the files.
- After conversion: check the state and download action for each result.
- Failures: retry a failed item without assuming that completed files also failed.
- Originals: keep them until all required outputs have been checked.
Frequently asked questions
Answers about PNG compression, file size, transparency, metadata, multiple files, and output quality.
Choose Privacy or Cloud, then select one or more HEIC or HEIF images. Processing starts automatically; download each successful PNG result.
PNG uses lossless compression for the output file, so the PNG encoder does not add JPEG-style compression artifacts. Conversion cannot restore image information that was already discarded when the HEIC source was created.
HEIC is designed to store photographs efficiently. PNG uses lossless compression and is commonly much larger for photographic content.
PNG supports transparency, but preservation depends on whether the source contains an alpha channel and whether the complete conversion pipeline reads and writes it correctly. Check the finished image instead of assuming it is preserved.
Both modes keep metadata supported by PNG and the conversion pipeline by default rather than intentionally stripping it. HEIC-specific HDR, depth, auxiliary-image, motion, or container-only data may not map to PNG.
Yes. Both modes accept multiple HEIC or HEIF images. Each successful source image produces a separate PNG. Download results individually or together as a ZIP; Cloud also accepts ZIP input.
Choose PNG when a workflow specifically requires PNG or losslessly encoded output. Choose JPG for ordinary photo sharing, broader compatibility, and usually smaller files.
Privacy converts the image in your browser without uploading it. Cloud uploads the image for server-side conversion, and uploaded images are deleted by default after one day.
Yes. Both Privacy and Cloud accept .heic and .heif images. Use the original file rather than changing its extension.
