PNG or JPG?
PNG keeps every detail and see-through parts, but the files are big. JPG is much smaller and is what most sites, emails and forms want. Anything see-through in your PNG turns white, because JPG can't be see-through. Drop the pictures in, then save them one by one or all together as a zip.
How to use it in 4 steps
- 1Drop your PNG pictures onto the box, or press Choose photos.
- 2Each one is converted straight away and shows a preview with its new size.
- 3Press Save for one file, or Save all as one zip.
- 4Send or upload the JPGs, which are usually much smaller than the PNGs.
Why turn a PNG into a JPG
PNG files are exact, which is why screenshots and graphics are saved that way, but photographs saved as PNG are very large. Converting a photo from PNG to JPG can cut the file size dramatically, which helps when you send it by email, upload it to a form with a size limit or put it on a website.
The trade-off is that JPG is a lossy format. It throws away tiny details you are unlikely to see, which is why the file is smaller. For sharp-edged graphics such as a logo or a screenshot with text, PNG may look better.
See-through parts become white
A PNG can have a transparent background. A JPG cannot, so this page fills the transparent parts with white. If you need the background kept see-through, keep the PNG, or convert it to WebP, which can hold transparency in a much smaller file.
Choosing a good result
For photos, the default quality is a good balance of size and detail. If the file is still too big for a form, try the Compress photo page. If you need an exact pixel size, use Resize image before or after converting.

A quick example: a screenshot for an upload form
A job application form accepts only JPG files up to 2 MB, and your scanned certificate is a 5 MB PNG. Drop it onto this page and the JPG usually lands well under the limit, because photographs and scans shrink dramatically when a PNG becomes a JPG. Check the size on the card before you save.
If it is still too big, put the JPG through Compress photo and nudge the slider down until the size is right.
Good to know
Zoom in on any text in the result. JPG can leave a slight halo around small letters, so for a document that has to be read closely it can be worth saving a larger picture instead of a smaller one. A PNG with a see-through background gets a white one, which is fine on a white page and looks wrong on a coloured one. Keep the PNG in case a form later asks for it.
Think about where the picture will be seen. On a phone screen the difference between a PNG and a good JPG is hard to notice, while the saving in size is large. On a printed page with small text, the cleaner PNG may still be worth the extra weight.

Questions people ask
Why is the JPG so much smaller?
PNG keeps every pixel exactly, which makes big files. JPG throws away tiny details the eye barely notices, so photos usually shrink a lot. Look at the sizes shown on each card to see the saving.
What happens to the see-through areas of my PNG?
JPG cannot be see-through, so those areas turn white. To keep them see-through, keep the PNG or turn it into a WebP with PNG to WebP.
Is JPG always better?
Not always. For photos, JPG is the better choice. For screenshots, logos and pictures with small text or sharp edges, PNG often looks crisper, and a JPG can look slightly fuzzy around the letters.
Can I choose the JPG quality?
This page saves at high quality. If you want a smaller file, drop the result into Compress photo and use the slider.
Are my pictures uploaded?
No. The conversion happens on your own device.
