JPEG vs PNG

JPEG commonly uses lossy compression and suits many photographs, while PNG preserves pixel values losslessly and supports transparency. The choice depends on image content, editing needs, and the destination's requirements.

Which format should you choose?

Consider JPEG for photographs when smaller files matter and transparency is unnecessary; use PNG for transparency, sharp-edged graphics, or lossless exports.

Export or convertExporting JPEG to PNG or WebP cannot restore data already removed by JPEG compression. Keep an original editing file, and use a proper export command rather than changing only the filename extension.Export PNG to JPEG only when transparency and lossless quality are no longer needed. Keep the original PNG for editing, and use a proper export command rather than changing the filename extension.

Export from the original source where possible. Compare the actual image at its intended size, inspect transparency and edge detail, and follow requirements for the receiving application or service.

  • JPEG is often efficient for photographs with gradual tones.
  • PNG is useful for interface graphics, screenshots, and transparent assets.
  • Neither format guarantees a smaller file for every kind of image.

Frequently asked questions

Should every image be saved as PNG?

No. PNG can be larger for photographs; choose based on content, transparency, and quality needs.
