Convert JPG to PNG for lossless editing

JPG is lossy: every time you save one, a little detail is discarded. Edit and re-save a JPG a few times and the degradation becomes visible. PNG is lossless, so once an image is in PNG form you can edit and re-save it indefinitely without further loss.

That makes PNG the right choice when an image is going into a design workflow, when you need to add a transparent layer, or when a platform specifically requires PNG.

One honest caveat: converting JPG to PNG does not restore quality that JPG already discarded. It preserves what is there from that point onward. It also produces a considerably larger file, because lossless storage costs space.

Who uses this most

  • Design work — Editing an image repeatedly without accumulating compression damage.
  • Adding transparency — Preparing an image for a cut-out or overlay.
  • Logos and graphics — Sharp-edged artwork looks noticeably better in PNG than JPG.
  • Platforms requiring PNG — Some upload systems and design tools accept only PNG.
  • Screenshots — Text and interface elements stay crisp in PNG.

How to use the jpg to png converter

  1. Add your JPG filesDrag in one or many images.
  2. Set any optionsResize if the destination requires specific dimensions.
  3. ConvertThe conversion is lossless and runs entirely on your device.
  4. Check the outputPNG files will be noticeably larger than the JPG originals; that is expected.
  5. DownloadSave individually or as a ZIP for batches.

Converting to PNG preserves the image as it currently is. It cannot recover detail that JPG compression already removed, so the result will never look better than the JPG you started with.

Common problems and how to fix them

The PNG is much bigger than the JPG

This is normal and expected. PNG stores every pixel exactly, which costs space. For photographs the file may be several times larger.

The image still looks compressed

Existing JPG artefacts are preserved, not removed. Converting cannot undo damage already done.

The background is not transparent

Converting does not create transparency; JPG has none to begin with. Use the background remover to make an area transparent.

The file is too large to upload

If size is the constraint, PNG is the wrong format for photographs. Stay with JPG and use the image compressor.

Colours look slightly different

PNG and JPG handle colour differently. The difference is usually negligible.

My PNG will not open in old software

Very old applications occasionally struggle with certain PNG variants. Converting back to JPG solves it.

Using PNG sensibly

  • Convert to PNG when an image is about to be edited repeatedly, so you stop accumulating loss.
  • Use PNG for logos, screenshots and line art; use JPG for photographs.
  • Expect a larger file — that is the cost of lossless storage.
  • Do not convert simply hoping to improve quality; that is not how it works.
  • If you need transparency, remove the background after converting.
  • For web use, consider WebP instead — it is smaller than both.

Your file never leaves your device

Conversion is performed inside your browser, so nothing is uploaded at any stage. This matters most when the document is personal — an Aadhaar or PAN scan, a bank statement, a salary slip, a medical report or a signed contract. With a server-based converter you are trusting an unknown company with that file. Here there is nothing to trust, because the file is never transmitted anywhere.

JPG to PNG Converter — more questions

Does converting JPG to PNG improve quality?

No. It prevents further loss from that point onward, but it cannot recover detail that JPG compression has already discarded.

Why is my PNG so much larger?

PNG is lossless and stores every pixel exactly, whereas JPG discards information to save space. Several times larger is normal for photographs.

Will the background become transparent?

No. Converting does not create transparency. Use the background remover to make an area transparent.

When should I use PNG instead of JPG?

For logos, screenshots, line art, images needing transparency, and anything you will edit repeatedly.

Can I convert several images at once?

Yes, add a batch and download the results together as a ZIP.

Is the conversion lossless?

The conversion itself is lossless. Any compression damage already present in the JPG remains.

Is there a file limit?

No fixed limit; your device memory is the practical constraint.

Are my images uploaded anywhere?

No. Everything happens locally in your browser.
