PNG to JPG Converter

Convert PNG images to JPG (JPEG) right in your browser. Pick a background color to flatten any transparency, batch-convert as many files as you like, and download them individually or as a ZIP — nothing is ever uploaded.

PNG → JPG — add as many as you like, converted in your browser

All conversion runs in your browser with the Canvas API — your files are never uploaded. Re-encoding also strips EXIF/location metadata.

Understanding the PNG to JPG Converter

A PNG to JPG converter changes lossless PNG images into compressed JPG (JPEG) files. PNG is excellent for graphics, screenshots, and anything needing transparency, but its files can be large and many platforms prefer JPG for photos. Converting to JPG shrinks the file using lossy compression, making images faster to upload, email, and share. The key trade-off is that JPG has no transparency channel, so any see-through areas in the PNG must be filled with a solid background color. This tool runs entirely in your browser using the Canvas API, so your PNGs are never uploaded and stay completely private.

How it works

The tool reads each PNG, decodes it into an off-screen HTML canvas, and fills the canvas with your chosen background color first so transparent pixels become solid. It then draws the image on top and re-encodes the canvas as JPEG at the quality level you set. Because JPG discards some detail to compress, you pick a quality between 10% and 100% to balance file size against sharpness. Each PNG is processed one after another, the original-versus-new size is shown, and you can save files individually or bundle several into a single ZIP — all without anything leaving your device.

Worked example

You export a 2.4 MB PNG screenshot to share by email. You set the background to white and quality to 85%. The converter flattens the transparent corners onto white and re-encodes it as JPG, producing a 280 KB file that looks virtually identical but is roughly nine times smaller and opens in any email client or photo viewer.

Tips & common mistakes

Pick a background color that matches where the image will sit — white for documents, or the page color for a seamless blend, since JPG cannot keep transparency.
Keep quality around 80–90% for photos; below 70% you may start seeing blocky JPG artifacts around edges and text.
Always keep your original PNG if the image has text, logos, or sharp lines — JPG compression softens those more than photos.
For logos or graphics that truly need transparency, stay with PNG or use WebP instead of converting to JPG.
Batch several PNGs at once and grab them as a ZIP to save time instead of converting one by one.

Frequently Asked Questions

Why is my PNG transparency gone after converting to JPG?

JPG has no transparency channel, so any transparent areas must be filled with a solid color. This tool flattens them onto the background color you pick (white by default), which is why the see-through areas become solid in the JPG.

Will converting PNG to JPG make the file smaller?

Usually yes. Photographs and screenshots saved as PNG are often much larger than the same image as JPG, because JPG uses lossy compression. Simple graphics with flat colors can sometimes stay smaller as PNG, but most photos shrink noticeably.

Is converting PNG to JPG lossy?

Yes. JPG re-compresses the image and discards some detail to save space. The default quality keeps it visually clean, but converting repeatedly between formats can slowly soften fine detail, so keep your original PNG if you may need to re-edit it.
