Best for
Not ideal for
Transparent backgrounds
JPG has no transparency, so transparent areas are filled — usually with white — when converting from PNG.
Very large files
Large files take longer and can hit browser memory limits — try a smaller sample first.
Skipping the output check
Compare the first rows or pages of the output with the input before using it in production.
Background
A website hero section uses a large PNG file that is slowing down page load times.
Problem
The image is too heavy for mobile users and lacks a solid background.
How to use
Upload the PNG, set quality to 75, and select a white background color.
quality: 75, backgroundColor: #ffffff, progressive: trueOutcome
A significantly smaller JPEG file that loads progressively, improving the site's Core Web Vitals.
Background
An internal document management system only accepts JPEG files for profile uploads.
Problem
User profile photos are currently saved as PNGs, causing upload errors.
How to use
Upload the PNG profile photo and convert it to JPEG without changing the quality settings.
quality: 85, backgroundColor: #ffffffSince JPEG does not support transparency, the tool fills transparent areas with your chosen background color, which defaults to white.
Yes, you can use the JPEG Quality slider (1-100) to balance between file size and image clarity.
A progressive JPEG loads in stages, displaying a blurry version of the image first that sharpens as it downloads, which is ideal for web performance.
By default, metadata is removed, but you can enable the 'Keep Metadata' option to preserve EXIF, IPTC, and XMP data.
Yes, the tool supports individual PNG files up to 50MB.
Outcome
A compatible JPEG file that is accepted by the document management system.
