Convert PNG to JPG — fast, free, 100% in your browser
Drop a PNG below, pick a quality level, and get a lighter JPG in a single click. Your files never leave your device — every conversion runs locally via the HTML5 Canvas API.
Your file is processed entirely in your browser. Nothing is uploaded.
PNG is a lossless format, which means every pixel of your image is preserved exactly — perfect for screenshots, UI mockups, logos, and any graphic with sharp edges. The trade-off is file size: a typical PNG photo weighs 3 to 5 times more than the same photo saved as a JPG. When you're emailing an album, uploading to a CMS, or publishing on a site where every kilobyte impacts your Core Web Vitals, those extra megabytes start to hurt.
Converting PNG to JPG typically cuts file size by 60 to 80 percent with a barely perceptible quality drop on photographs. The FileShrink PNG to JPG converter runs entirely in your browser using the HTML5 Canvas API. That means zero uploads, zero server storage, and zero logging. You can even disconnect your network once the page has loaded — the tool keeps working. Drop a file, adjust the quality slider, and download the result in one click.
How to convert PNG to JPG in 4 steps

Pick a quality level
The default is 85, which gives an excellent balance between file size and visual fidelity. Raise it to 95 for archival quality, or lower it to 70 for the smallest possible file.

Wait a moment
Conversion runs in your browser using the Canvas API. A 10 MB PNG typically finishes in under a second on a modern laptop.

PNG vs JPG: what is the difference?
PNG uses lossless compression, meaning every pixel is preserved exactly as captured. It supports transparency through an alpha channel, which is why designers pick it for logos, icons, and user-interface assets. The downside is that PNG compression is inefficient on photographs — a 4000x3000 photo can easily weigh 20 MB in PNG. JPG, also known as JPEG, uses lossy compression specifically tuned for photographs. It discards visual information the human eye barely notices, producing much smaller files at the cost of a small quality reduction. JPG does not support transparency: when you convert a transparent PNG to JPG, the transparent pixels are replaced with a solid background, white by default. The practical rule is simple: photographs go to JPG, screenshots and anything with sharp edges or transparency stays as PNG.
When should you convert PNG to JPG?
Emailing photos
Most email providers cap attachments at 25 MB. Converting PNG screenshots and photos to JPG lets you fit five to ten times more images per message.
Publishing on the web
Smaller JPGs mean faster page loads, better Largest Contentful Paint, and better Google rankings. Switching hero images from PNG to JPG can shave one to two full seconds off your LCP.
Saving disk and cloud storage
Batch-converting a folder of PNG photos to JPG can free several gigabytes. For photo libraries this adds up to significant monthly cloud-storage savings.
Uploading to JPG-only platforms
Some forums, marketplaces, and legacy document editors still reject PNG uploads. Converting to JPG makes your files compatible without changing the visible image.
Frequently asked questions
- Will I lose quality converting PNG to JPG?
- JPG is lossy, so a small amount of information is always discarded. At quality 85 to 90 the loss is invisible on photographs. On screenshots containing crisp text or thin lines, you may notice slight compression artifacts — consider keeping those as PNG or raising quality to 95 or higher.
- Why does my transparent PNG become a JPG with a white background?
- The JPG format simply does not support transparency. During conversion, FileShrink fills transparent pixels with a white background by default. If you need to preserve transparency, keep the image as PNG or convert to WEBP instead.
- Is there a file size limit?
- The only limit is your device’s available memory. Most modern laptops handle PNG files up to 100 to 200 MB without issue. Mobile browsers may struggle above 50 MB because of stricter memory caps.
- Can I convert several PNG files at once?
- Yes. Drop as many PNG files as you like into the dropzone, or select several at once in the file picker — up to 50 per batch. They convert one after another so your browser never runs out of memory, each file gets its own download button as soon as it is ready, and a "Download all" button bundles the finished JPGs into a single ZIP. A file that fails to convert does not stop the others.
- Does FileShrink store a copy of my file?
- No. The entire conversion happens inside your browser using the HTML5 Canvas API. No file is ever uploaded, stored, or logged. You can verify this by disconnecting your network once the page is loaded — the tool keeps working because there is no server call involved.
