What converting JPG to PNG does — and doesn't — do
A common misconception is that converting a JPG to PNG will "restore" or "improve" image quality. It can't. JPG is a lossy format: when the image was first saved, fine detail was permanently discarded. PNG is lossless, so it faithfully preserves whatever pixels are in the JPG right now — but it cannot recover what was already thrown away. Your PNG will look exactly like the JPG.
What you do gain is a format that won't degrade further. Every time you re-save a JPG, it loses a little more. A PNG can be opened, edited, and re-saved any number of times with zero additional loss.
When this conversion makes sense
- You're going to edit the image. Working in PNG avoids stacking JPG artefacts with each save.
- A tool or platform requires PNG. Some design software, app icon pipelines, and printers prefer or demand it.
- You'll add transparency. You can't make a JPG transparent, but once it's a PNG you can erase a background in an editor.
- You need crisp text or lines. If the JPG has visible "ringing" around edges, a PNG copy won't add more.
For photos, the PNG will usually be 2–5× larger than the JPG. That's normal — it's the price of lossless storage. If size matters more than losslessness, stay with JPG or try WebP.
How to convert
- Output is already set to PNG (the quality slider is disabled because PNG is lossless).
- Drop your JPG files onto the zone above, or click to browse.
- Download each PNG individually, or download everything as a ZIP.
