Add up to 30 PNG images (up to 50 MB each) and convert them to JPG at a quality you choose (10 to 100, default 85). Transparent areas are filled with white, black or any custom color, since JPG has no transparency. You can also pick WebP or AVIF as the output, and the conversion runs in your browser.

JPG is the most widely accepted image format, and for photos and screenshots it is usually much smaller than PNG. This PNG to JPG converter changes the format, lets you set the quality, and replaces transparency with the background color you pick.
How to convert PNG to JPG
- Add your PNG files by dragging them in or clicking to browse.
- Keep JPG as the output and adjust the quality.
- Choose a background color for transparent areas: white, black or a custom color.
- Download the JPG files one by one or together as a ZIP.
Why convert PNG to JPG?
Every browser, device, email client and social network accepts JPG, so it is the safe choice for sharing. JPG compression makes photos and detailed screenshots much smaller than PNG, which helps pages load faster on phones and slow connections and improves Core Web Vitals scores such as Largest Contentful Paint.
What the converter offers
The quality slider goes from 10 to 100, and the preview shows the result before you download. Image dimensions stay the same. Transparent areas are filled with white by default, or black, or any color from the color picker, which matters for logos and graphics. Each batch takes up to 30 files with the same settings, and several results can be downloaded as a ZIP.

Understanding the PNG to JPG conversion tradeoff
Converting PNG to JPG trades transparency and exact pixels for a smaller, more compatible file. JPG compression splits the image into 8 × 8 pixel blocks and discards fine detail the eye notices least, using the discrete cosine transform (DCT). That works very well for photos and badly for sharp text, flat colors and thin lines, which can pick up visible artifacts.
When PNG to JPG makes sense
The conversion suits product photos, blog images, social media uploads, email newsletters, and anywhere file size and compatibility matter more than an exact copy. A large PNG screenshot of a photo often shrinks to a small fraction of its size as a JPG at quality 85 with no visible difference. Photos of people, landscapes and products with smooth gradients compress especially well.
When to avoid this conversion
Keep the PNG if the image needs transparency, contains text or sharp edges, is a logo or icon with flat colors, will be edited further, or must stay pixel-perfect. A transparent logo converted to JPG gets a solid background and can no longer be placed over other content. Screenshots of text can show smudges around the letters. For those images, keep PNG or use PNG to WebP, which keeps transparency.
The JPEG quality number
The quality slider sets how much detail JPG compression discards. At 100 files are large with almost no artifacts, and at 10 they are tiny but blocky and banded. For most photos, 80 to 90 gives a much smaller file with no visible loss, and 60 to 75 is fine for small thumbnails and backgrounds. For the background color, use white for logos on light websites, black for dark themes, or your site's background color.
Who uses it
Web developers convert PNG graphics and create JPG fallbacks. Content creators convert screenshots for social media and blog posts. Office users convert logos for presentations and email, and store owners convert product images for their shops.
Technical specifications
Input is PNG, and output is JPG, WebP or AVIF. Each batch takes up to 30 files of up to 50 MB and 64 megapixels each. Quality goes from 10 to 100. Processing happens in your browser, and files are never uploaded or stored on a server.
Frequently Asked Questions
Will PNG transparency be preserved in JPG?
No. JPG can't store transparency, so transparent areas are filled with the background color you choose (white by default).
What quality should I use for PNG to JPG conversion?
Start at 80 to 90 and lower it if the file is still too big. Higher quality means a larger file with fewer artifacts.
Can I convert multiple PNG files to JPG at once?
Yes. Add up to 30 PNG files and convert them all with the same settings, then download them as a ZIP.
Is this PNG to JPG converter really free?
Yes. There are no fees, watermarks or sign-up.
Will the image quality be affected?
JPG is lossy, so some detail is lost. At quality 80 to 90 the loss is usually invisible in photos, while text and sharp edges show it sooner.
What's the maximum file size I can convert?
Each PNG can be up to 50 MB and 64 megapixels.
Can I choose a custom background color?
Yes. Choose white, black, or any color from the color picker to fill transparent areas.
Why does my converted JPG look different from the original PNG?
JPG compression discards some visual data, which can cause slight color shifts and artifacts, especially at low quality settings. At 85 to 90 the difference is usually invisible in photos but may show around text and sharp edges. Transparent areas also become your chosen background color.
Should I use PNG or JPG for my website?
Use PNG for transparency, logos, icons, text, sharp edges and flat-color graphics. Use JPG for photos and product images where file size matters more than an exact copy. Most sites use both, each for the images it suits.
