About this tool

Some upload forms and internal tools require the .jpeg spelling and quietly reject .jpg — even though the underlying format is identical. This converter exists for those workflows: take a PNG, get back a JPEG-encoded file with the extension you need. As with any PNG-to-JPEG conversion, transparent pixels are flattened onto a background because JPEG has no alpha channel. The encode is lossy, which is what buys the smaller size. Processing happens in the browser, one file at a time, up to roughly 25MB.

FAQ

More about this tool

How it works

  1. Upload a PNG from your device or drop it into the picker.
  2. The browser encodes the image using JPEG compression.
  3. Download the .jpeg file when it is ready.

Features

  • Extension aware — The output uses the .jpeg naming preferred by some legacy systems.
  • Same underlying format — Byte-for-byte, .jpeg files and .jpg files are interchangeable.
  • Alpha channel dropped — PNG transparency is flattened during the JPEG encode.
  • Smaller than the source — Photographic PNGs typically shrink significantly when saved as JPEG.
  • Runs locally — Your PNG is never sent to a remote server.

Supported formats

Input: PNG. Output: JPEG (.jpeg).

Common uses

  • Satisfying strict file rules — Send .jpeg to systems that specifically list JPEG as the accepted format.
  • Consistent asset naming — Standardize on .jpeg across an archive of mixed PNG and JPG files.
  • Emailing photos — Shrink bulky PNG exports before attaching them to messages.

Limitations

  • Any transparency in the PNG is lost.
  • JPEG encoding is lossy, so the result differs from the PNG pixel-perfectly.
  • Single file per conversion, roughly 25MB cap.
  • Line art and text can show ringing artifacts.
