FAQ

How do I convert a JPG to PNG?

Drop a .jpg or .jpeg file on the upload area or click it to browse. Check the preview, click Convert to PNG and then Download PNG. The file keeps its original name with a .png extension, and the Output Size is shown before you download.

Does converting JPG to PNG improve image quality?

No. The PNG is a lossless copy of the JPEG pixels at the same width and height, so existing JPEG compression artifacts remain, but no further quality is lost. PNG files are usually larger than the JPEG they come from.

Will the PNG have a transparent background?

No. JPEG has no transparency, so the PNG keeps the same opaque background as the original image. Converting only makes transparency possible in later edits with an image editor.

Can I convert several JPG files at once?

No, the converter handles one image at a time. Click Remove to clear the current file and upload the next one. Only JPG and JPEG files are accepted; other formats show an error message.

Does the PNG keep the photo's EXIF data?

No. The image is redrawn on a canvas before it is saved as PNG, so EXIF metadata such as camera model, date and GPS location is not copied into the new file.

Is my image uploaded to a server?

No. The image is decoded and converted with the HTML5 canvas inside your browser, so the file never leaves your device.
