Converts on your device — nothing is uploadedConvert JPG to PNG — Free, Private, In Your Browser
This JPG to PNG converter turns a JPG or JPEG image into a lossless PNG without ever uploading your file. The conversion runs entirely in your browser using the HTML5 Canvas, so your image stays on your own device from start to finish — nothing is sent to a server, nothing is stored, and there is no sign-up, no watermark, and no software to install. Upload a JPG, press Convert, preview the result side by side with the original, and download your PNG. It is genuinely private and instant.
How to Convert JPG to PNG
The tool follows three clear steps, shown in the progress bar above:
- Add your JPG — drag and drop it onto the drop zone, click to browse, or paste from your clipboard. The original appears with its dimensions and file size.
- Convert — press Convert to PNG. The PNG is generated locally and its preview and file details appear in the panel beside the original.
- Download — press Download PNG to save the lossless file to your device. Use Choose another to convert the next image.
Does Converting JPG to PNG Make the Background Transparent?
This is the most common misunderstanding, so it is worth stating plainly: no, converting JPG to PNG does not create a transparent background. A JPG has no transparency information to begin with — every pixel must have a solid colour — so your converted PNG will show exactly the same background as the original.
What the conversion actually gives you is a PNG file that is ready for transparency. PNG supports an alpha channel (a fourth value per pixel controlling opacity) that JPG lacks, which is why designers convert to PNG before making a background transparent. To get an actual transparent background you need a separate background-removal step afterwards — in an editor such as Photoshop or GIMP, or with an AI background remover. Converting the format and removing the background are two different jobs; this tool does the first, reliably and losslessly.
JPG vs PNG — What's the Difference?
| Feature | JPG / JPEG | PNG |
|---|---|---|
| Compression | Lossy (discards detail) | Lossless (keeps every pixel) |
| Transparency | Not supported | Yes (alpha channel) |
| Best for | Photographs | Logos, graphics, screenshots, text |
| File size | Smaller | Larger (typically 3–5×) |
| Re-saving | Loses quality each time | No further loss |
| Edges & text | Can look fuzzy (artifacts) | Stays sharp |
When Should You Convert JPG to PNG?
A quick way to decide: if it is a photograph and you do not need transparency, JPG is usually the better format. Convert to PNG when you need one of PNG’s strengths:
- You are about to remove the background — you need PNG’s alpha channel before making anything transparent.
- Logos, icons, and graphics — flat colours and hard edges stay crisp in PNG, with no JPG blocking artifacts.
- Screenshots, diagrams, and images with text — PNG keeps fine lines and letters sharp where JPG blurs them.
- Editing without cumulative loss — PNG is lossless, so repeated edits and saves will not degrade the image.
- A platform or app that only accepts PNG — sometimes the destination simply requires it.
Will Converting Improve or Restore Quality?
It is important to be realistic: converting to PNG cannot restore detail that JPG compression already threw away. Those pixels are gone, and any existing JPG artifacts will still be visible in the PNG. What conversion does is capture your JPG exactly as it is now in a lossless container, so from this point on the image will not degrade any further. That makes JPG→PNG a useful archival step before a round of editing — you avoid a second pass of lossy re-encoding that a JPG-to-JPG workflow would introduce.
Is It Safe and Private?
Yes — and this is where an in-browser converter really matters. Because everything happens locally through the Canvas API, your image is never uploaded, never copied to a remote server, and never stored after you close the tab. Many online converters send your file to their servers and promise to delete it later; here there is nothing to delete, because the file never leaves your device. That makes it a safe choice for confidential, personal, or client images.
A Note on File Size
Because PNG stores every pixel losslessly, a PNG is usually several times larger than the same image as a JPG — the converter shows you both sizes so there are no surprises. If your priority is a small file and you do not need transparency or lossless quality, the PNG to JPG Converter or the JPG to WebP Converter is the better choice. If you need transparency support, pixel-perfect accuracy, or crisp text and edges, PNG is worth the extra size.
Frequently Asked Questions
How do I convert a JPG to PNG?
Add your JPG (drag, click, or paste), press Convert to PNG, then press Download PNG. The whole process runs instantly in your browser.
Does converting JPG to PNG make the background transparent?
No. Your PNG keeps the same solid background as the JPG. Conversion gives you a PNG that supports transparency, but making the background transparent is a separate background-removal step in an editor.
Will converting restore lost quality?
No — it cannot recover detail JPG compression already discarded, but it stops further loss. Once in PNG, editing and re-saving will not degrade the image.
Is this converter free?
Completely free, with no sign-up, no watermark, and no limit on how many images you convert.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser via the HTML5 Canvas, so your image never leaves your device.
Why is my PNG larger than the JPG?
PNG is lossless and stores every pixel exactly, so it is typically several times larger than a lossy JPG. If small size matters and you do not need transparency, consider WebP.
Does the PNG keep the same dimensions?
Yes. The PNG has exactly the same width and height as the original JPG — only the format and compression change.
