What does the PNG to JPG converter do?
PNG and JPG are the two most common image formats, and each is better at different jobs. PNG is lossless and supports transparency, which makes it ideal for logos, icons and screenshots with text. JPG uses lossy compression that makes photos dramatically smaller, which is why cameras, phones and most websites use it for pictures.
Problems start when an image is in the wrong format: a 6 MB PNG screenshot of a photo that a form rejects, or a JPG logo that shows a white box instead of a transparent background. This tool converts in both directions. Leave it on Swap automatically and every PNG becomes a JPG and every JPG becomes a PNG, or force one format for the whole batch.
When a PNG has transparent areas and you convert it to JPG, those areas need a colour, because JPG can't be transparent. White is the default; pick any colour that matches where the image will be used. Converting JPG to PNG won't restore detail lost in the original JPG compression, but it stops further loss when you edit and save the file again.
Using the PNG to JPG / JPG to PNG Converter for your business
Choosing the right format matters at scale: a store with large PNG product shots can be several times heavier than it needs to be. Our ecommerce SEO service fixes formats and compression across the whole catalogue, and our technical SEO team makes sure the speed gains show up in Core Web Vitals.

Why use this converter
Two-way conversion
PNG to JPG and JPG to PNG in the same tool, even in one batch.
Much smaller photos
A photo saved as PNG often shrinks by 70–90% as a JPG.
Clean transparency handling
Choose the background colour instead of getting black edges.
Checks the real format
Renamed files are detected, so you always know what you're converting.
When to use PNG and when to use JPG
Use JPG for photographs, product shots on real backgrounds and anything with gradients and lots of colours. It keeps file sizes small, which matters for email, upload forms and page speed.
Use PNG for logos, icons, illustrations with flat colours, charts and screenshots containing text. These have sharp edges that JPG compression makes fuzzy, and they often need transparent backgrounds.
For websites there's a third option worth considering: WebP. It supports transparency like PNG and compresses photos better than JPG, so one format can replace both. Most modern browsers support it, and our Image to WebP converter can switch your files over.
A quick way to decide: open the image and ask whether it has transparent parts or crisp text. If it does, keep it as PNG. If it's a photo, a JPG will look the same and load much faster. For online stores, consistent JPG or WebP product photos at the same dimensions also make category pages look tidier and load faster on mobile.
Is it safe to upload my files?
Your files are processed on our own server, not sent to any third-party service, and are deleted automatically 30 minutes after processing. We strip location data from photos when converting them, and we never use your files for anything else.
Frequently asked questions
Does converting PNG to JPG reduce quality?
Slightly, because JPG is lossy. At quality 90 it's very hard to see, and the file is usually far smaller.
Why does my PNG get a white background as a JPG?
JPG can't store transparency, so transparent pixels are filled with the background colour you choose.
Will converting JPG to PNG improve quality?
No. It prevents further loss when you edit and re-save, but it can't bring back detail the JPG already lost.
Can I convert both formats in one batch?
Yes. With Swap automatically, PNGs become JPGs and JPGs become PNGs in the same batch.
Is there a file limit?
Up to 10 files of 10 MB each per batch.
