JPG to PNG Converter
Convert JPG images to PNG instantly and privately in your browser. PNG is lossless, so you get a crisp, editable copy of every pixel — with no uploads, no signup and no watermark.
What is the JPG to PNG converter?
JPG is a lossy, compact format built for photographs, which is why it is everywhere — but it throws away detail every time it is saved and cannot hold transparency. PNG is the opposite: lossless, preserving every pixel exactly, and capable of a transparent background. For graphics, logos, screenshots and anything you want to keep editing, PNG is usually the better choice.
This JPG to PNG converter decodes a JPG and re-encodes it as a PNG right in your browser using the Canvas API. The result is a faithful lossless copy that you can crop, layer or save over and over without degrading. Converting a JPG will not magically restore detail that was already lost to compression, but it stops further quality loss from piling up.
Because everything runs locally, your image never leaves your device — no uploads, no queues, no accounts.
How to use the JPG to PNG converter
- Click Choose a JPG image and select the file.
- The PNG preview is generated instantly — no settings required.
- Click Download PNG to save the lossless copy.
Example
A 300 KB JPG at 80% quality is converted to PNG. The result is roughly 1.1 MB because PNG is lossless, and every pixel is identical to the JPG as it appeared — ready for further editing without any added artefacts.
Common use cases
- Keep editing an image repeatedly without degrading it further.
- Prepare a graphic or logo for a transparent background.
- Make crisp, clean screenshots and scans for documents and presentations.
- Preserve full-quality detail when archiving your photos and designs.
Pro tips
- PNG files are much larger than JPG, so convert only when you need lossless quality or transparency.
- Pair the conversion with a background remover if you want true transparency.
- Converting cannot recover detail already lost to JPG compression — only stop it getting worse.
- Resize before you convert to keep the PNG file size manageable.
FAQ
Is the JPG to PNG converter free?
Yes — free and unlimited, with no signup and no watermark.
Does converting JPG to PNG improve quality?
It preserves the image losslessly, but it cannot recover detail that JPG compression already discarded — it just prevents further loss.
Why is the PNG bigger than the JPG?
PNG stores every pixel losslessly while JPG compresses by discarding detail, so the same image takes more bytes as a PNG.
Does PNG support transparency?
Yes — PNG supports a transparent background, which is a big reason to convert from JPG.
Can I edit the PNG afterwards?
Yes. Because PNG is lossless, you can crop, resize and resave repeatedly without quality loss.
Do my images stay private?
Yes. The conversion runs entirely in your browser, so your images never leave your device.
What are PNGs best used for?
Graphics, logos, screenshots and images with text or sharp edges, where lossless quality and transparency matter.
Does converting delete my original JPG?
No — the converter only creates a new file and never touches the original.
Does JPG to PNG keep the same resolution?
Yes. The conversion preserves the exact pixel width and height of the source image. Only the encoding changes, never the dimensions.
Can I convert a JPG to a transparent PNG?
A JPG file does not store transparency, so converting it to PNG keeps the original background. To get a truly transparent background you need to remove the background first.
