Free PNG to JPG Converter: Fast, Private and No Sign-Up
PNG and JPG are two essential image formats online, but PNG files are frequently oversized for everyday web use, blogs, and email sharing. Converting PNG images to JPG dramatically slashes file size while keeping high visual clarity, ensuring that websites load quickly and storage isn't wasted.
The PromptCraft Studio PNG to JPG Converter converts files right inside your browser. No software installs, no registrations, and zero server uploads. Drop your PNGs, choose your quality level, and download the compressed JPG files instantly.
Why convert PNG to JPG?
- Dramatic file size reduction: PNG's lossless compression often yields huge file weights. JPG compresses photographic elements efficiently, cutting file sizes by 60% to 80%.
- Fast website performance: Heavy PNG assets slow down page rendering. Converting banner images and product photos to JPG improves SEO and Google Core Web Vitals.
- Universal upload compatibility: Many web forms, profile uploaders, and legacy systems reject PNGs or limit upload file size. JPG is universally accepted.
- Adjustable compression: Unlike PNG, JPG lets you choose an exact compression quality to fit your storage and bandwidth limits.

Your photos stay on your device
Most online converters send your files to an external cloud server to process. This converter does not. Processing runs 100% on your device using client-side HTML5 canvas APIs. Your private images and client media never travel over the internet, providing complete confidentiality.
Handling transparent backgrounds
The JPG format does not support transparency. On basic converters, clear PNG backgrounds often turn harsh black. This tool gives you full control with an integrated background color picker, letting you set a clean white, dark, or customized brand color fill behind transparent graphics.
Frequently Asked Questions (FAQ)
Is this PNG to JPG converter completely free?
Yes. You can convert unlimited PNG files with no watermarks, daily limits, or paid upgrades.
Does this tool store or upload my images?
No. Everything is rendered locally in your browser cache. Once you close the tab, all image buffers are wiped.
Why did my transparent PNG get a white background?
JPG cannot store alpha transparency channels. Any transparent areas are automatically filled with the color selected in your background settings (white by default).
Can I convert multiple PNG files at once?
Yes. Select or drag as many files as you like. They will convert simultaneously, and the Download all button will save them one after the other.
What quality setting should I use?
90% provides a perfect balance of sharp visual quality and substantial file size savings. If you need maximum file compression for fast page loads, 80% is ideal.
