What this conversion is for

Converting JPG to PNG is about stopping further loss, not undoing past loss. A JPG re-saved as JPG degrades a little with every save; the same image as PNG can be opened, edited and saved a hundred times and stay pixel-identical. That makes PNG the right working format the moment a JPG enters an editing pipeline — and the right answer when a form, plugin or printing service flatly refuses anything but PNG.

The conversion happens in your browser: the JPG is decoded to raw pixels and re-packed losslessly. Up to 20 files at a time, downloadable as a ZIP.

Honest expectations

  • Quality: identical to the JPG you dropped in — no better, no worse. PNG faithfully preserves whatever the JPG had, including its existing compression artifacts.
  • Size: substantially larger. Lossless pixel storage costs several times the bytes of JPEG's perceptual compression.
  • Transparency: the format now supports it, but you'd add it in an editor afterwards — the photo itself converts fully opaque.

Common real-world reasons

People land on this page because: an online editor or meme generator only accepts PNG; a CMS or app-store listing requires PNG assets; a print shop asked for PNG to avoid another JPEG generation; or a document workflow needs images that won't shift in appearance between saves. If your actual goal is a smaller file rather than a lossless one, you want the image compressor instead — PNG conversion makes files bigger, not smaller.

Frequently asked questions

Does converting JPG to PNG improve quality?
No — and any tool claiming otherwise is misleading you. Detail discarded when the JPG was saved is gone. What PNG gives you is a copy that won't degrade any further, no matter how many times it's edited and saved.
Why is the PNG so much bigger than my JPG?
PNG stores every pixel exactly, with no lossy compression. A 500 KB JPG routinely becomes a 3–5 MB PNG. That's the cost of losslessness, and it's normal.
When do I actually need a PNG?
When a tool or workflow demands it: editors that only accept PNG, print pipelines, app stores or CMS fields with PNG-only inputs, or as a stable master before repeated editing. Also as the starting point for adding transparency in an editor.
Will the converted PNG have transparency?
It will support transparency, but the picture itself stays fully opaque — JPGs have no transparent pixels to carry over. You'd add transparency afterwards in an image editor.
Is the conversion done on a server?
No. The pixels are redrawn into PNG format by your own browser. Nothing is uploaded, which also means there are no file-size limits beyond your device's memory.
