JPG to PNG
Convert JPG images to PNG in your browser. Lossless output, perfect for editing or layering. Your photos never leave your device.
Runs in your browser — nothing uploaded
Convert a JPG (or JPEG — same format) to PNG in one click. Useful before editing in software that prefers lossless input, when you need to add transparency, or when a platform requires PNG uploads.
Private by design — your data never leaves your device
How to use it
No account, no upload — it all happens on your device.
1
Drop a JPG file into the box, or click to choose one.
2
PNG is lossless — there's no quality setting.
3
Click Download. The PNG arrives with the same filename and a .png extension.
What you gain by switching to PNG
- Lossless re-saves.Once a JPG, always a JPG with compression baked in. Saving as PNG won't recover detail — but it stops any further loss from edits and re-exports.
- Transparency support. PNG has a real alpha channel. After conversion you can erase the background in an image editor.
- Sharper edges.If you crop and re-export, PNG won't add halos around text and lines the way JPG does.
What you don't gain
- Better quality.JPG's compression artifacts are permanently encoded into the pixel data. Converting to PNG preserves them — it doesn't undo them.
- Smaller files. PNG is almost always bigger than JPG for photographs. If size matters, WebP is the better choice.
Tips
- If your goal is editing, work from a PNG copy and keep the original JPG untouched.
- If your goal is transparency, remember you still have to remove the background — the conversion alone makes the format transparency-capable, not the image transparent.
- For batch jobs, use the Image Compressor with PNG as the output format.
- Going the other way? See PNG to JPG. For a smaller file with transparency, see the WebP Converter.
Frequently asked
Why convert JPG to PNG?
Two main reasons: PNG is lossless, so re-saves don't add new artifacts (good for editing pipelines), and PNG supports transparency, which lets you erase a background without re-exporting from the original. Note that a JPG converted to PNG keeps all the JPG artifacts that were already there — PNG can't undo lossy compression.
Will the file get bigger?
Yes, often a lot. JPG is highly compressed at quality 80–90; PNG is lossless and stores photo noise inefficiently. A 200 KB JPG photo can become a 2 MB PNG. If you only need PNG for transparency, consider WebP — same alpha support, JPG-class file sizes.
Is my JPG uploaded anywhere?
No. The conversion runs entirely in your browser through the HTML canvas API. Your image is never uploaded or stored on any server.
