JPG to PNG

Convert a JPEG to PNG with optional resizing. Conversion does not remove backgrounds or restore lost detail.

How to Use JPG to PNG

Follow these steps, then review the result and the limitations below:

  1. Choose a valid JPG or JPEG file.
  2. Leave dimensions blank to retain its decoded size, or enter one dimension for proportional resizing.
  3. Click Process Image and download the PNG after checking its preview and byte size.

Practical Worked Example

A 120 × 60 JPEG exported without resizing produces a 120 × 60 PNG named converted.png. The image stays opaque; a white background does not automatically become transparent.

Key Features & Capabilities

  • Task-specific controls with labelled fields and status feedback.
  • Processing uses browser APIs without a tool upload request.
  • Invalid input is reported before a successful output is offered.

Export a JPEG as PNG for an editing workflow

Choose this converter when a destination accepts PNG or you need a PNG copy for a later edit. Conversion does not remove the JPEG background or repair compression artifacts already present in the photograph.

How It Works (Technical Overview)

The browser decodes the JPEG and exports its canvas pixels using the PNG encoder. Output MIME type is checked before a download link is offered.

Real-World Use Cases & Applications

  • Export a JPEG as PNG for an editing workflow. Check the worked example before processing your own input.

Privacy, Security & Accuracy

PNG output can be substantially larger than the JPEG. Source JPEG artifacts remain, and camera metadata is not intentionally copied. This is not background removal. Practical limits depend on browser support and available memory. Files above 20 MiB are rejected; raster processing is limited to 16 million pixels and output dimensions to 8192 pixels per side.

Pro Tips for Best Results

Check the result against your original and the requirements of the destination. Keep an unchanged source copy.

Frequently Asked Questions

Does PNG make a JPEG lossless again?

No. PNG preserves the newly decoded pixels without restoring information discarded by earlier JPEG encoding. Keep the original for reference.

Is my input uploaded for processing?

The tool code works in the browser. The page can also load advertising or analytics scripts, which have separate data practices. Avoid sensitive files on an unsuitable device or page.
