Choose a format for the image you have
PNG and JPG solve different problems. PNG preserves sharp edges and transparent backgrounds without discarding image data. JPG uses lossy compression: it reduces detail to store photographs more compactly. Changing the file extension alone does not convert an image; this tool decodes the PNG and creates a new JPG at 88% encoder quality.
When converting makes sense
A large PNG photograph can be awkward to attach to an email or upload to a website. A JPG copy often makes those tasks easier. For example, a 2400 × 1600 photo can be converted here, then reduced to 1200 × 800 in the image resizer if the destination only needs a smaller image. Check the downloaded file size and preview before using it.
When to keep PNG
Keep PNG for logos with transparent backgrounds, diagrams, and screenshots where small text must remain crisp. JPG has no transparency, so this converter fills transparent pixels with white. Compression can also create visible artifacts around lettering. Keep your original PNG so you can make another export later.
How to use the converter
- Select a PNG from your device. An image that your browser cannot decode will show an error.
- Choose Convert to JPG. The preview shows the white background and exported appearance.
- Download the JPG copy and compare its size and sharpness with the original.
Limits and privacy
The converter processes one image at a time in this tab. It accepts files up to 10 MB and rejects decoded images above 20 million pixels to reduce memory use. A device may struggle with images below this limit; try a smaller original if conversion fails. Closing the page discards the browser's working copy. No account is required.
Will the JPG always be smaller?
No. PNG can be efficient for flat-color graphics, while JPG usually suits photographs better. Pixel dimensions, image detail, and encoder settings all affect the result. Use the actual download size rather than assuming one format is always better.
