What happens when JPG becomes PNG

Format sumber

JPG uses lossy compression and does not support transparency.

Format sasaran

PNG uses lossless compression and supports full transparency.

Apa perubahan

The JPG pixels are decoded and written using PNG compression and color capabilities.

Apa yang disimpan
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
What may be lost
Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when PNG supports them.
Codec and quality implications
Writing PNG without further lossy compression avoids additional codec loss, but it does not restore detail discarded by the JPG encoding.
Realistic limitations
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Langkah Konversi

  1. Upload a JPG file no larger than 1 GB.
  2. Confirm that PNG is selected as the target.
  3. Start the conversion. A healthy compatible worker begins processing immediately.
  4. Download the PNG file and check the result before deleting your source.

Penyelesaian masalah

The JPG file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The PNG file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.

Privasi dan penyimpanan file

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
