How to convert JPEG to PNG

  1. Drop your JPEG files onto the converter above — or click to browse.
  2. Click Convert on a single file, or Convert all to process everything at once.
  3. Download individually or click Download all for a ZIP archive.
  4. Tip: PNG output is lossless — no further quality loss when re-saving from this point forward.

JPEG vs PNG — understanding the difference

JPEG and JPG are the same format — two names for the same standard (Joint Photographic Experts Group). JPEG is the original full extension; JPG is the shortened 3-character version that became common on Windows. They are processed identically by every tool and browser.

PNG is a lossless format that stores image data without any quality reduction. Where JPEG compresses and discards detail to achieve smaller file sizes, PNG preserves all original pixel values. PNG files are larger but can be re-saved indefinitely without accumulating compression artifacts.

When JPEG to PNG conversion is useful

  • Switching to a lossless editing workflow — once PNG, no further compression on re-save
  • Preparing images for use in presentations where sharp text and graphics are needed
  • Converting JPEG logos or product shots to PNG for use in design tools
  • Using images on websites where pixel-perfect clarity matters over file size

Frequently Asked Questions

What is the difference between JPEG and JPG?
No technical difference. JPEG is the full name of the format standard; JPG is the shortened file extension. On older Windows systems, file extensions were limited to 3 characters — hence .jpg. Modern systems accept both. The format, compression, and quality are identical.
How do I convert JPEG to PNG online?
Drop your JPEG files onto the converter above, click "Convert all", then "Download all". The PNG output is lossless — no further compression is applied. Everything runs in your browser, no upload needed.
Does the PNG output have better quality than the JPEG?
The PNG captures the JPEG at its current quality level — it does not restore detail lost during JPEG compression. However, going forward the PNG will not degrade further on re-save, unlike JPEG.
Will the PNG file be much larger than the JPEG?
Yes — PNG files are typically 3–8× larger than the equivalent JPEG for photographs. PNG stores pixel data losslessly, so more data per pixel compared to JPEG's compressed representation.
Can I convert multiple files at once?
Yes. Drop as many files as you need in one go and click "Convert all" to process everything at once. When done, click "Download all" to get a single ZIP archive containing all converted files.
Are my files uploaded to a server?
No. All conversion happens directly in your browser using the Canvas API. Your files never leave your device — no uploads, no server processing, 100% private. This also means the tool works without an internet connection once the page has loaded.
