JPG to PNG Converter

Convert a JPEG image into a PNG file without sending it to PagesTools. The output preserves the pixels the browser can decode, but it cannot reverse earlier JPEG compression.

What JPG to PNG Converter does

JPG to PNG Converter verifies and decodes one JPEG, then writes the visible image to a PNG canvas export. PNG is useful for workflows that require a lossless raster format or specifically request a .png file.

The conversion prevents additional JPEG loss in the new export, but existing blocks, ringing, and blur remain part of the decoded image. A PNG made from a JPEG may also be larger because PNG compresses photographs differently.

How to use JPG to PNG Converter

  1. Choose one valid JPG or JPEG file up to 20 MB.
  2. Confirm the selected file and start the PNG conversion.
  3. Review the output size and download the generated PNG.

Important details

Lossless output does not restore lost detail

PNG stores the converted pixels without JPEG-style loss, but information discarded when the source JPEG was created is already gone. The result should look like the decoded source, not an original uncompressed photo.

File size can increase

PNG is efficient for flat graphics and sharp edges but can be much larger for photographs. Compare the output size before replacing a JPEG used on a bandwidth-sensitive page.

Practical uses

  • Supply a PNG to a design tool or form that rejects JPEG files.
  • Move a JPEG into a lossless editing workflow before making additional saves.
  • Create a PNG version of a photo for a mixed-format asset package.

Privacy and limitations

The JPEG is validated, decoded, and encoded as PNG on your device. Its bytes are not sent to a PagesTools conversion server.

One JPEG up to 20 MB can be processed at a time, subject to 12,000-pixel-side and 40-megapixel canvas limits. The output does not gain transparency, layers, vector paths, or quality missing from the source.

Common questions

Frequently asked questions

Does PNG conversion remove JPEG artifacts?

No. Artifacts are visible pixels after the JPEG is decoded and are copied into the PNG. Removing them would require a separate restoration or editing process.

Why is the PNG larger than the JPG?

PNG uses lossless compression, while JPEG is designed to compress photographic detail with controlled loss. A photographic PNG is therefore often larger even when both files have the same dimensions.

Can the output have a transparent background?

The PNG format supports transparency, but converting an ordinary JPEG does not identify or remove its background. The generated PNG remains fully opaque unless transparency is added later in an editor.
