About this tool
There are honest reasons to turn a JPG into a PNG even though the file gets bigger. PNG never degrades an image further: every time a JPG is opened and re-saved by an editor, a little more detail melts away, while a PNG stays pixel-perfect through years of edits. Designers need PNG for logos and graphics, many print and documentation workflows prefer it, and if you plan to crop, annotate or combine a photo repeatedly, a PNG master copy protects your work.
This converter re-saves your JPG as a true PNG inside your browser, instantly and privately — nothing is uploaded. It cannot invent detail the JPG already threw away, and no honest tool can; what it does guarantee is that from this copy onwards, nothing more is lost. The PNG will normally be several times larger than the JPG, and that larger size is the honest price of lossless storage.
A common workflow: a form or a relative sends you a JPG, you convert it to PNG once, do all your editing on the PNG, and only export a fresh JPG at the very end if a small file is needed. That way the image is compressed exactly once in its life instead of a little more at every step.
How to use it
- Drop your JPG onto the panel above, or click it to choose the file.
- Press 'Convert to PNG' — the conversion happens instantly on your device.
- Check the new size, preview the result, then press 'Download PNG' and keep it as your master copy.
Where it is used
- Creating a safe master copy of an important photo before cropping or annotating it.
- Preparing images for design tools and documents that require PNG input.
- Saving screenshots and scans in a format that will not degrade with repeated saving.
- Workflows where a portal or printer specifically asks for PNG files.
Tips for a better result
Do not convert back and forth repeatedly — JPG to PNG to JPG cycles only grow files and add nothing. Decide which copy is your master (the PNG) and which is your delivery copy (a JPG, when small size matters) and keep both. And remember the limit of every converter: if the original JPG is blurry or heavily compressed, the PNG will be a perfect copy of that same blurry image — faithful, but not sharper.
