What this tool does

It decodes your PNG file and re-encodes the pixels as JPG at the quality you choose (92% by default — visually identical for photos). The file is read, converted and offered back as a download without touching the network.

About PNG

PNG is the lossless raster format of the web: every pixel is stored exactly, with an optional alpha channel for transparency. It was designed in 1996 as a patent-free replacement for GIF and is supported by literally everything that shows images. It is good for screenshots, logos, icons, UI graphics, anything with sharp edges, flat colour or text, and anything that needs a transparent background; less good for photographs — a photo saved as PNG is typically 5–10× larger than the same photo as a good-quality JPEG with no visible benefit. Universal: every browser, OS, editor, office suite and messaging app since the late 1990s.

About JPG

JPEG (files end in .jpg or .jpeg — they are the same thing) is the 1992 lossy photo format that every camera, phone and website understands. It throws away detail the eye is bad at seeing, which is why a photo can be 10× smaller than as PNG while looking identical at normal viewing sizes. It is good for photographs and anything photo-like, email attachments, marketplaces and forms that demand .jpg, and situations where compatibility matters more than anything; less good for text, line art, screenshots and logos (the compression smears sharp edges into visible "ringing"), and anything that needs transparency — JPEG has none. Universal, and the safest choice when a form, portal or older program insists on a specific format.

What changes going from PNG to JPG

  • Transparency is lost. JPG has no alpha channel, so transparent areas are filled with white. If that matters, convert to PNG or WebP instead.
  • Quality: JPG is lossy. At the default 92% nothing is visible; lower the slider for smaller files.
  • Size: Small for flat graphics, very large for photos (a 12-megapixel photo is 20–30 MB as PNG) vs. typically 100 KB–4 MB for a phone photo depending on quality; re-saving a JPEG loses a little more quality each time.
  • Metadata: EXIF (camera, date, GPS) is not carried over — the browser decodes pixels, not tags. That is a privacy plus for sharing and a minus if you rely on dates in the file.

What you give up and gain

You gain a file that is usually 3–10× smaller and accepted by every form and marketplace on earth. You give up transparency (filled with white here — pick a different colour by using the background tool first) and perfect fidelity: JPEG is lossy, so a logo or screenshot will show faint fringes around text at lower quality. Keep the quality slider at 85–92% for anything with text or sharp edges; photos tolerate 70–80%.

How to convert PNG to JPG

  1. Drop the PNG file on the panel above or click to choose it.
  2. JPG is pre-selected; adjust the quality slider if you need a smaller file. Press Convert to JPG.
  3. Download. The file is named after the original with a .jpg extension.

Frequently asked questions

Is my PNG file uploaded?

No. The page is static and has no upload endpoint; your browser does the work on your own device and the result is saved straight back to your disk. The site's Content-Security-Policy only allows it to talk to its own origin, so it cannot send your file anywhere even by accident. Load the page, disconnect from the internet, and it still works.

Does PNG to JPG lose quality?

JPG is a lossy format, so strictly yes — but at the default 92% quality the difference from the PNG is invisible at normal viewing size. Lower the slider only if you need a smaller file.

Will transparency survive?

No — JPG cannot store transparency. Transparent pixels become white. Use PNG or WebP as the target if you need it.

Is it free? Any limits or watermark?

Free, no account, no watermark, no daily quota. Because nothing runs on our servers there is nothing to meter. The only limits are your device's memory — anything up to roughly 50 megapixels is fine on a modern phone or laptop.

Can I do several files at once?

One file at a time at the moment — drop the next one as soon as you have downloaded the first. Batch processing with a ZIP in and out is planned.

Does it work on my phone?

Yes — iPhone, iPad and Android browsers all run it. Large files take a few seconds longer on a phone than on a laptop.
