  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: converting JPG to PNG does not recover quality lost during previous JPG compression — it only stops further degradation.

JPG vs PNG — when does converting make sense?

JPG (JPEG) uses lossy compression — every time a JPG is edited and re-saved, the algorithm re-encodes the image and discards more detail. After several rounds of editing, compression artifacts become visible. PNG is lossless — once in PNG format, re-saving never degrades quality.

Converting JPG to PNG is the right move when you plan to edit an image multiple times, add text overlays, or use it in a design workflow. The resulting PNG will be larger than the JPG but will not accumulate any further quality loss.

Important: converting JPG to PNG does not restore quality

If your JPG already has compression artifacts — blurry edges, blocky areas, color noise — those artifacts are baked in and will appear in the PNG. Conversion captures the JPG at its current state in a lossless container. Use PNG going forward to prevent further degradation.

Common reasons to convert JPG to PNG

  • Editing in Photoshop, GIMP, or Affinity Photo — avoid re-saving as JPG during the workflow
  • Adding a transparent background (requires removing background in an editor after conversion)
  • Using images in presentations or documents where white backgrounds should be transparent
  • Creating web graphics where lossless sharpness is needed for logos or UI elements

Frequently Asked Questions

How do I convert JPG to PNG online for free?
Drop your JPG files onto the converter above, click "Convert all", then "Download all". Conversion happens in your browser — no account, no software, no upload needed.
Will converting JPG to PNG improve the image quality?
No. The conversion captures the JPG at its current quality in a lossless PNG container. Any JPEG compression artifacts already in the image will remain. What you gain is that no further quality loss occurs on future re-saves.
Why is the PNG so much larger than the JPG?
PNG is lossless — it stores more pixel information than JPG. For photographs, PNG files are typically 3–8× larger than the equivalent JPG. This is the trade-off: larger file, but no quality loss on editing.
How do I get a transparent background after converting JPG to PNG?
Converting JPG to PNG does not automatically add transparency — it just changes the container format. To make a background transparent, open the PNG in an editor like Photoshop, GIMP, or remove.bg and manually remove the background layer.
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.
