PNG too heavy for an email or a form?
PNG is a lossless format: perfect for editing, but very heavy for a photo. A smartphone image or a large screenshot can exceed 5 MB as a PNG, while messaging apps and government sites often limit attachment size. Converting to JPG greatly reduces the size while keeping a sharp image.
When should you keep PNG instead of JPG?
JPG is ideal for photos and images rich in gradients. For a logo, an icon, a diagram with small text, or an image that needs to keep a transparent background, it's better to stay in PNG: JPG removes transparency and can create a slight blur around sharp edges. In that case, to reduce file size, try “Compress Image” instead.
Go further with your images
If the JPG is still too heavy, reduce its dimensions with “Resize Image”. To gather several images into a single document to send, use “JPG to PDF”. All these conversions happen in your browser, for free and with no sign-up.
Frequently Asked Questions
Why convert a PNG to JPG?
Mainly to save space: a JPG is much lighter for a photo, which makes it easier to email and upload to size-limited sites.
What happens to my PNG's transparency?
JPG doesn't support transparency: it's replaced with a white background, or the color of your choice.
What quality should I choose for the JPG?
A high setting gives a result visually identical to the original. Lower it if you need a lighter file, checking that the details stay sharp.
Can I convert several PNGs at once?
Yes, add as many images as you want, then download all the JPGs in a ZIP archive.
