Turn PNG images into JPGs. Set the quality and replace transparent areas with your chosen color.

How to convert PNG to JPG

Add one or more PNG files, up to 25 MB each. JPG is already selected. Adjust quality in the top controls for the batch, or change a single row. Click Download next to an image or Download all to convert and save the batch.

What happens to a transparent background?

JPG cannot store transparency. This tool checks each PNG for transparent pixels. When they are present and JPG is selected, the Background control lets you choose a fill color. White is the default. For a PNG with no transparent pixels, no background control is needed.

Choosing JPG quality

The initial setting is 85%. Lower quality can reduce file size but may introduce visible artifacts, especially around text and sharp edges. Higher quality usually creates a larger file. JPG is lossy even at 100%; keep your original PNG if you need an unchanged source.

When should I keep PNG instead?

Keep PNG for transparent logos, screenshots with small text, and graphics where sharp edges matter. JPG is often useful for photographs or services that require JPEG. JPG and JPEG refer to the same image format; this tool saves the .jpg extension.

Dimensions, privacy and limits

Conversion keeps image dimensions and does not upload your files. The output is a new file, not a renamed PNG. Animated PNG inputs become still images. Processing large batches depends on your device memory; try fewer files at a time if a conversion fails.

Overridden images use their own settings.

A few useful answers before you convert or resize.

How do I resize images?

Open Resize in the menu. Each image starts at its original dimensions. Edit width or height in pixels and download. The linked chain icon automatically updates the other dimension using the original aspect ratio. Batch width or height applies separately to each unchanged image. Enlarging is allowed; a warning appears when an output is larger than its original because it may look softer or pixelated. Unlink the chain icon to edit dimensions independently, which can stretch an image. Each row can override the batch settings.

Resize keeps the original PNG, JPG or WebP format, including transparency for PNG and WebP. JPG and WebP are re-encoded at 85% quality. GIF resizing is not supported. Use Convert to change formats or adjust quality and background colors. Resizing runs locally and is completely free.

How do I change an image format online?

Choose images or drag files onto the canvas. Select JPG, PNG or WebP in the output format control, then use the download button beside an image or Download all. The tool converts and downloads your images in one step. No account or image upload is required.

How do I convert PNG to JPG?

Add your PNG images and choose JPG as the output format. Adjust quality if needed. If a PNG has transparent pixels, choose a background color because JPG cannot preserve transparency. Select Download all for the batch, or download an individual image from its row.

Can I convert WebP to PNG or JPG?

Yes. Add WebP images and select PNG to preserve existing transparency, or JPG for an opaque image. You can also convert JPG or PNG to WebP in compatible browsers. Changing the format does not restore detail already lost through compression, and a different format is not guaranteed to produce a smaller file.

Are JPG and JPEG the same format?

Yes. JPG and JPEG are different filename extensions for the same image format. You can add either to this converter; JPEG output is downloaded with the .jpg extension.

Are my images uploaded?

No. Image previews, transparency checks and conversions happen in your browser. The converter does not upload your images or filenames. Visiting the website still involves loading it from a host; see the Privacy Policy for details about analytics, advertising and your choices.

Which image formats can I use?

You can add PNG, JPG, WebP and GIF images, up to 25 MB per file. Choose JPG, PNG or WebP as the output. Support depends on your browser. Animated images are not preserved as animations when converted.

Can I convert several images at once?

Yes. Select multiple files or drag them onto the canvas. Use Download all to convert and save the batch, or the download button in a row to save only that image. Files download individually, not as a ZIP. Allow multiple downloads if your browser asks.

How do the shared settings work?

The format, quality and background controls above the canvas set the defaults. New images and rows using defaults follow those settings automatically. Changing a row gives it its own settings. Use its reset button to return it to the current defaults.

Why can’t I change quality for PNG?

PNG uses lossless encoding, so there is no adjustable quality setting. On the Convert page, JPG and WebP have a quality slider: lower values can reduce file size but may lose detail. The Resize page uses 85% quality for JPG and WebP. Converting a previously compressed image to PNG will not restore lost detail or guarantee a smaller file.

When can I choose a background color?

On the Convert page, the background picker is available when a PNG or WebP image has detected transparency and you choose JPG output. JPG cannot keep transparency, so those areas are filled with your chosen color. Resize keeps the original format and has no background picker. A PNG or WebP file without transparent pixels does not need this control. PNG and WebP output can preserve existing transparency; conversion does not remove a solid background.

Can I preview or rename an image?

Click its thumbnail to open a larger preview of the original. Edit the image name in its row to change the download filename. The output extension is added automatically; your original file is not renamed or modified.

Why did a download fail or not appear?

Check whether your browser blocked multiple downloads and look in its downloads list. If a row reports an error, try downloading it individually or choose another output format. Very large image dimensions can exceed browser memory even when the file is below 25 MB. Keep your originals and check downloaded results.

What happens when I remove an image or close the tab?

Removing a row clears it from the converter, not from your device. Refreshing or closing the page ends the working session; the tool does not keep a saved image library. Your original files and any copies you have downloaded remain on your device.

Is the tool free?

Yes. All image conversions and downloads are completely free. There are no fees, subscriptions or sign-up requirements. Advertising helps support the service. Ad availability depends on Google approval, your privacy choices and available ads; unused advertising spaces remain blank.
