HEIC to PNG vs JPG: Which Format Should You Choose?

What Happens When You Convert HEIC to PNG?

When a HEIC or HEIF image is converted to PNG, the image is decoded from the source file and encoded into the PNG format.

PNG uses lossless encoding. This means the PNG encoding process does not use the same type of lossy compression normally associated with JPG.

However, converting an existing HEIC image to PNG does not recreate image information that is not present in the source file. It also does not automatically improve the visual quality or resolution of the original photo.

The resulting PNG can also be larger than a JPG version of the same photo, especially for detailed photographic images.

What Happens When You Convert HEIC to JPG?

When you convert HEIC or HEIF to JPG, the source image is decoded and encoded as a JPEG image.

JPG uses lossy compression, which makes it possible to reduce file size by discarding some image information during encoding.

For photographs, JPG can often provide a useful balance between visual quality and file size.

HEICJPGOnline also provides JPG output controls that let you choose a JPEG quality setting or use Target File Size when the resulting JPG needs to stay within a particular maximum size. See how to convert HEIC to JPG to a specific file size, or use our HEIC to JPG converter to start converting.

HEIC to PNG vs JPG: Key Differences

When Should You Convert HEIC to PNG?

HEIC to PNG can be a useful choice when:

• the website, application or workflow you are using specifically requires PNG;
• you need a widely supported PNG output for editing or another compatible workflow;
• you want the converted output encoded using PNG's lossless encoding;
• reducing the image to the smallest practical file size is not your main priority.

For photographs, PNG files can become significantly larger than JPG files. If file size is important, compare PNG and JPG output before deciding which format better suits your needs. You can create PNG output using our HEIC to PNG converter.

When Should You Convert HEIC to JPG?

JPG can be a practical choice when:

• you are converting photographs for general viewing or sharing;
• smaller file size is important;
• a website or form accepts JPG;
• you want direct JPEG quality control;
• you need to keep each output image within a particular maximum file size.

For example, HEICJPGOnline's Target File Size option can attempt to keep each JPG at or below targets such as 20 KB, 50 KB, 100 KB, 200 KB, 500 KB or larger supported limits.

Use the file-size requirement of the destination website or service rather than automatically choosing the smallest possible output.

Does Converting HEIC to PNG Improve Image Quality?

No. Converting an existing HEIC image to PNG does not increase the resolution or restore image information that is not available in the source.

PNG uses lossless encoding for the new PNG file, but that does not mean the conversion can recover information that was already absent from the HEIC source.

Choose PNG because the PNG format matches your intended workflow, not because you expect the conversion itself to enhance the original photograph.

Why Can PNG Files Be Larger Than JPG?

PNG and JPG use different approaches to image compression.

PNG uses lossless encoding, while JPG is designed to achieve smaller image files through lossy compression.

Photographs often contain large amounts of color variation, texture and fine detail. PNG must represent that image information without JPEG-style lossy compression, so a PNG version of a photograph can require considerably more storage.

Actual output size depends on the source image and its contents, so do not assume that every PNG will have a particular size relative to JPG.

Can I Batch Convert HEIC to PNG?

Yes. HEICJPGOnline supports batch HEIC to PNG conversion.

You can select up to 100 supported HEIC or HEIF files per batch, with a maximum of 50 MB per file and 500 MB total per batch.

Each source image is converted into its own PNG output.

After conversion, individual PNG files can be downloaded separately, or Download All can save the successfully converted PNG files together as a ZIP archive.

Because HEIC decoding can use significant browser memory, very large or high-resolution batches may perform differently depending on the device, browser and available memory.

For demanding batches on mobile devices, processing fewer high-resolution images at a time may improve reliability.

Is HEIC to PNG Conversion Private?

On HEICJPGOnline, selected HEIC and HEIF images are processed locally in the browser for conversion.

The selected image files are not uploaded to our servers for conversion or stored on our servers as part of the conversion process.

Because the processing workload runs on the user's device, performance can depend on browser capabilities, available memory and image resolution.

PNG or JPG: How to Decide

Choose PNG when you specifically need PNG output or a workflow that benefits from PNG's lossless encoding.

Choose JPG when you are working primarily with photographs and smaller file sizes, JPEG quality control or a specific maximum output size is more important.

Neither format is the best choice for every situation.

If you are unsure, check the accepted formats and file-size requirements of the website, application or workflow where the converted image will be used.
