PNG to JPG Converter
Quick answer
Turn a PNG into a JPEG for anywhere that will not take transparency or wants a smaller file, such as an email attachment, a WordPress hero image, or an old upload form. The catch is the alpha channel, which is why this tool asks you to pick a background colour before it converts anything.
What the png to jpg converter does
JPEG has no concept of transparency. Every pixel gets a red, green, and blue value and nothing else, so a PNG logo with a see-through background has to be flattened onto something solid before it can become a JPEG at all. Pixora handles that with a background colour picker, set to white by default, which fills in every transparent and semi-transparent pixel before the JPEG encoder ever sees the image.
This is also where most size savings live. A PNG screenshot with flat colour compresses fine on its own, but a PNG of an actual photograph is usually several times larger than the same photograph as a JPEG at quality 85, because PNG cannot throw anything away and JPEG can.
One case where you should not make this conversion: a screenshot of text. JPEG compresses colour at half resolution by default, a trick called 4:2:0 chroma subsampling, and that is exactly why coloured text on a JPEG often looks smeared at the edges. Text screenshots belong in PNG or lossless WebP, not JPEG.
How to use it
Upload the PNG
Drag it in or click to browse. Files with no transparency skip straight to encoding.
Pick a background colour
White is the default matte colour for any transparent pixels. Change it if the PNG will sit on a coloured page or a dark background.
Set JPEG quality
75 to 85 keeps the image visually close to the original at a fraction of the PNG file size.
Download the JPEG
The result is a standard .jpg ready for email, upload, or a CMS media library.
Your images never leave your device
The flattening and the encode both happen on the canvas in your browser tab. That matters if the PNG is a marketing mockup for a product that has not shipped yet, since design teams often convert unreleased packaging renders this way, and a browser-only tool means the render never sits on a third-party server while it waits.
- No file is ever uploaded to a server
- Works offline after the first visit
- No account, no watermark, no limits
Format and quality tips
White is not always the right matte
Placing the PNG on a dark website background after flattening to white leaves a visible box around the subject. Sample the destination background colour and use that instead.
Do not convert flat-colour graphics this way
A simple logo or icon with large flat areas usually gets bigger, not smaller, as a JPEG, since JPEG is tuned for photographic noise, not hard edges. Keep those as PNG or WebP instead.
Frequently asked questions
Why do I need to pick a background colour to convert PNG to JPG?
Because JPEG cannot store transparency. Any pixel that was see-through in the PNG has to be filled with a solid colour first, and the picker controls what that colour is.
What happens to transparent pixels in a PNG to JPG conversion?
They are flattened onto the matte colour you choose, white by default. There is no way to keep partial transparency in a JPEG output, since the format has no alpha channel at all.
Will a PNG to JPG conversion make my file smaller?
For photographs, almost always, often by 70 to 90 percent at quality 85. For flat-colour graphics like logos or icons, JPEG can end up larger than the original PNG.
Is it safe to convert a screenshot of text to JPG?
It works, but it usually looks worse. JPEG subsamples colour at half resolution, which makes coloured text edges look smeared. Keep text screenshots as PNG.
Does converting PNG to JPG lose quality?
Yes, JPEG is a lossy format, so some detail is discarded during the encode. At quality 85 or above the loss is rarely visible to the eye, but it is not reversible.
Can I undo a PNG to JPG conversion later?
Not fully. Converting the JPEG back to PNG stops further loss but does not bring back detail JPEG already discarded, and the transparency is gone permanently once it has been flattened.
