Convert JPG images to PNG format.
Drag and drop a JPG/JPEG file into the upload area or click to browse. The tool checks both the file extension and MIME type to ensure it is a valid JPEG image.
After upload, the tool displays the file name and size so you can confirm you’ve selected the correct image before starting the conversion.
Click the Convert to PNG button. The tool renders the image onto a canvas and encodes a new PNG version in memory. A simple timeout protects against extremely large or slow-to-process images.
When conversion completes, the preview panel on the right shows the converted PNG image, scaled to fit while preserving aspect ratio.
Click the Download PNG button to save the new image to your device. The file name is derived from the original JPG name with a .png extension.
Use the Reset button to clear the current image, output, and any errors. Then upload another JPG or JPEG to repeat the process.
Does this JPG to PNG tool upload my images to any server?
No. The conversion is done completely inside your browser using a canvas. Your images never leave your device.
Why does the tool accept only JPG or JPEG files?
The tool checks both the MIME type and the file extension. Only .jpg and .jpeg images are allowed to ensure accurate conversion and avoid decoding errors.
Will my PNG output lose quality?
No. PNG is a lossless format, and the tool exports your image at full quality. The output is an exact pixel copy of your original JPG.
Why does conversion fail sometimes?
Conversion may fail if the JPG is corrupted, extremely large, or the browser cannot decode the file. Trying a different image or browser usually resolves the issue.
Why is only one image processed at a time?
This converter is designed for single-image processing. After downloading the PNG, you can upload a new JPG and repeat the process.
Does the converted file keep the same name?
Yes. The tool keeps your original filename and simply replaces the .jpg or .jpeg extension with .png.
Why does the preview sometimes not appear?
If the browser blocks the image URL or fails to decode the blob, the preview may not display. Refreshing the page or re-uploading the file often fixes this.
Does this tool remove EXIF metadata?
Yes. Since the JPG is redrawn onto a canvas, all metadata including GPS, camera info, and timestamps is removed automatically.
