PNG to JPG and JPG to PNG: Convert Free Without Uploading
Updated June 2026 · 4 min read
Converting between PNG and JPG is one of the most common image tasks there is - you need a smaller file to email, a JPG for a form that rejects PNG, or a PNG because you need a transparent background. The catch with most "free image converter" sites is that they upload your picture to a server first. Here is how to convert PNG to JPG (and JPG to PNG) for free, in full quality, without your image ever leaving your computer.
PNG vs JPG: which one should you use?
The two formats are good at different things, so the right choice depends on the image:
- JPG (JPEG) uses lossy compression and produces small files. It is the best choice for photographs and any image with smooth color gradients. It does not support transparency.
- PNG uses lossless compression and supports transparency. It is the best choice for screenshots, logos, diagrams, and images with sharp text, where JPG would add fuzzy artifacts around the edges.
So convert PNG to JPG when you want a smaller file and do not need transparency, and convert JPG to PNG when a tool or website specifically needs a PNG.

How to convert PNG to JPG (or JPG to PNG)
- Open the image converter.
- Drag in one or more images. They are processed on your device, not uploaded.
- Choose your output format: JPG or PNG (WebP and AVIF are also available).
- For JPG, pick a quality level. 80 to 90 percent keeps the image looking identical while cutting the file size.
- Click convert and download. A single image downloads on its own; a batch comes back as a ZIP.
Will I lose quality?
Converting to JPG applies lossy compression, so technically some data is discarded - but at a high quality setting the change is invisible to the eye, and the file is far smaller. Converting to PNG is lossless, but remember it cannot restore detail that a JPG already threw away; it just rewraps the same pixels in a lossless container, usually at a larger size. If you are converting a JPG to PNG hoping to "improve" it, the quality will not increase.
Tips
- Need a transparent background? Use PNG, and remove the background first with the background remover.
- Want the smallest possible file? Convert to JPG, then run it through the image compressor.
- Putting images in a document? You can skip the conversion and send them straight to a PDF with images to PDF.
