What actually happens when you convert PNG to JPG

This conversion is lossy and one-way. Two things change, and one of them catches people out.

Compression becomes lossy. PNG stores pixels exactly; JPEG approximates them in order to be small. Detail is discarded during the save, and it cannot be recovered by converting back. If you may need the original later, keep the PNG.

The alpha channel is destroyed. This is the important one. JPEG has no concept of transparency. Every transparent or semi-transparent pixel in your PNG must be flattened onto a solid colour before it can be saved.

In practice that means a logo saved as a transparent PNG, converted to JPG and then placed on a dark website, arrives with a solid rectangle around it. There is no way to undo this — the transparency information is gone from the file, not merely hidden. If your image has transparency you want to keep, convert to WebP instead, which supports both lossy compression and an alpha channel.

Size: for photographs the saving is dramatic. A 22 MB photographic PNG typically becomes 1.5–3 MB as a JPEG at good quality, with no visible difference at normal viewing size. For screenshots and flat graphics the saving is much smaller and the quality cost much higher.

When to convert PNG to JPG

  • A photograph was saved as PNG and is now far larger than it needs to be.
  • You are hitting an upload size limit — job portals, government forms, and email attachments are the usual culprits.
  • A system accepts JPEG only, which is still common in older CMS platforms and some print submission workflows.
  • You are producing many photo thumbnails where bandwidth matters more than pixel-exactness.

When not to

  • The image has transparency you need. Use WebP, or keep the PNG.
  • The image is a screenshot containing text. JPEG's block-based compression produces visible ringing around letterforms. Text becomes noticeably fuzzy at exactly the sizes people read it. Keep screenshots as PNG.
  • Logos, icons, line art, and diagrams. Same reason — sharp edges are precisely what JPEG handles worst, and flat colour is precisely what PNG handles best. You will often end up with a larger file that looks worse.
  • Master copies you will keep editing. Every JPEG re-save degrades the image further.

FAQ

PNG to JPG Converter FAQ

Frequently asked questions about this converter.

They are filled with a solid background colour, because JPEG cannot store transparency. This cannot be reversed afterwards. If you need transparency, convert to WebP instead.

No. Converting back produces a PNG that losslessly preserves the already-degraded image. The detail JPEG discarded is permanently gone.

JPEG is designed for photographs — smooth gradients and natural noise. Screenshots are the opposite: hard edges and large flat areas. Those edges produce visible ringing artifacts. Screenshots should stay as PNG.

For photographs, typically 85–95% smaller. For screenshots and graphics, often very little smaller, and sometimes larger.

Conversions use a high-quality 90% compression setting to balance visual fidelity with reduced file size.
