Convert PNG images to JPG format online for free. Upload one or multiple PNG files, choose your JPG quality and background color, then download the converted images directly from your browser.
What Is a PNG to JPG Converter?
A PNG to JPG converter changes an image stored in PNG format into the JPG image format. JPG uses lossy compression, which often creates smaller files than PNG, especially for photographs and other images with many colors.
This converter processes your selected images in the browser. The conversion uses the HTML Canvas API to render each PNG and export the result as a JPG file. The browser supports JPG encoding through canvas methods such as toBlob(). 1

PNG vs JPG
| Feature | PNG | JPG |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | Supported | Not supported |
| Photographs | Usually larger | Usually smaller |
| Logos and graphics | Often preferred | Useful when smaller file size matters |
| Sharp text and screenshots | Usually better | Compression can introduce artifacts |
| Typical extension | .png | .jpg or .jpeg |
What JPG Quality Should You Use?
JPG quality controls how strongly the image is compressed. A higher setting usually preserves more visual detail while producing a larger file. A lower setting creates a smaller file but introduces more compression.
| Quality | Best Use | Expected Result |
|---|---|---|
| 90% to 100% | High-quality photos and important images | High image quality, larger files |
| 75% to 89% | Web pages and general sharing | Good balance between quality and file size |
| 50% to 74% | Smaller web images | Smaller files with visible compression in some images |
| 10% to 49% | Situations where file size is the priority | Strong compression and reduced image quality |
The best setting depends on the original image. A quality value of 90% is a useful starting point for general conversion. Canvas JPG encoding accepts a quality value between 0 and 1, with higher values representing higher requested quality. 2
What Happens to Transparent PNG Images?
PNG supports transparent pixels, while JPG does not. When a transparent PNG is converted to JPG, the transparent portions need an opaque background.
This converter lets you choose the background color before conversion. White is selected by default because it works well for most photographs, documents, product images and general-purpose graphics.
For a logo with transparency, choose a background color that fits the intended use. For example, a black background might work better for a white logo than the default white background.
Does Converting PNG to JPG Reduce Image Quality?
PNG and JPG use different compression approaches. JPG uses lossy compression, so converting a PNG to JPG can remove some image information. The amount of visible change depends on the JPG quality setting and the contents of the image.
Photographs often tolerate JPG compression well. Screenshots, text-heavy graphics, line drawings and logos often show compression artifacts more easily.
Does PNG to JPG Conversion Change Image Dimensions?
No. This converter keeps the original pixel dimensions during conversion. For example, a 1920 x 1080 PNG is converted to a 1920 x 1080 JPG.
The tool changes the image format and compression, not the width or height. The browser draws the source image onto a canvas using its original dimensions before creating the JPG output.
Why Convert PNG to JPG?
- Reduce the size of photographic images.
- Prepare an image for websites or platforms requiring JPG.
- Make images easier to share or upload.
- Convert PNG screenshots or graphics for systems accepting JPG only.
- Standardize a collection of images in JPG format.
- Choose a specific compression level for a target file size.
PNG to JPG for Website Images
JPG remains useful for photographs and other images where a smaller file size matters. Before publishing an image, check the final dimensions, visual quality and file size rather than choosing the highest compression automatically.
If an image contains transparency or sharp text, keeping PNG might produce a better result. If the image is a photograph and transparency is not required, JPG often provides a more practical file size.
Is This PNG to JPG Converter Free?
Yes. The converter is designed for free browser-based use. No paid conversion API is required.
Are My Images Uploaded to a Server?
No. The conversion is performed inside your browser using JavaScript and the Canvas API. Your selected local image files are processed on your device by this page.
Browser-based processing also avoids sending the selected PNG files to a separate conversion service. The Canvas API supports drawing images and exporting the resulting canvas image into formats such as JPG. 3
