Convert to PNG
PNG uses lossless encoding, so this conversion won't restore detail already lost to JPEG compression — it just re-saves the image you see now as a PNG. The resulting file can be larger than the original JPG; that's normal for PNG.
JPG images don't contain transparency, so converting to PNG won't remove or change the background. The visible image stays exactly as it is.

About this JPG to PNG converter
This tool converts JPG and JPEG images to PNG entirely in your browser using the HTML canvas element. Your image is decoded, redrawn, and exported as a PNG file locally — nothing is ever uploaded to a server.
How to convert JPG to PNG
Upload a JPG or JPEG image and click "Convert to PNG." Preview the result, check the actual file size, and download the converted PNG.
JPG vs PNG: what's the difference?
JPG uses lossy compression and is one of the most widely supported image formats, offering small file sizes for photos. PNG uses lossless compression and supports transparency, making it common for graphics, screenshots, and images with sharp edges or text — but it usually produces larger files than JPG for photographic content.
Does converting JPG to PNG improve image quality?
No. JPEG compression is lossy, so any detail already lost when the image was originally saved as JPG can't be recovered by converting it to PNG. This tool re-saves the image you see now in a lossless format — it doesn't restore quality that's already gone.
Will JPG to PNG make my image transparent?
No. JPG images never contain transparency, so converting one to PNG doesn't create, add, or remove any transparency or background. The visible image stays exactly as it currently appears.
Why can the PNG be larger than the JPG?
PNG's lossless compression preserves every pixel exactly, which often takes more space than JPG's lossy compression — especially for photos. It's normal and expected for a converted PNG to be noticeably larger than the original JPG.
Is my image uploaded?
No. Conversion happens locally in your browser using canvas — your image is never sent to ToolLora's servers or any third party.
Frequently asked questions
Is this JPG to PNG converter free?
Yes — completely free, with no account and no limits on how many images you convert.
Are my images uploaded?
No. Conversion happens locally in your browser — your image is never uploaded to ToolLora's servers.
Does this restore quality lost when the image was saved as JPG?
No. JPEG compression is lossy, so detail lost when the image was first saved as JPG can't be recovered. Converting to PNG just re-saves the current image losslessly from this point forward.
Does converting to PNG remove the background?
No. JPG files don't contain transparency, so there's no background to remove. The PNG shows the exact same image as the original JPG.
Why is my PNG larger than the original JPG?
This is normal. PNG's lossless compression typically produces larger files than JPG, especially for photos — it doesn't mean anything went wrong.
Does conversion change image dimensions?
No. The PNG keeps the exact same width and height as the original JPG. Use the Image Resizer if you also need to change dimensions.
Can I use this tool on my phone?
Yes. The converter works on mobile browsers — tap "Choose JPG Image" to select a file from your device.
