PromptCraft Studio - JPG to PNG Converter
Convert JPG and JPEG photos to PNG in one click. Your files never leave your browser.
PNG is lossless, so the converted file is usually larger than the original JPG. That is normal.
Free JPG to PNG Converter: Fast, Private and No Sign-Up
JPG and PNG are the two image formats you meet most often online, and each one is good at a different job. JPG is small and great for photos. PNG is lossless, keeps sharp edges clean and supports transparency. Sometimes a design tool, a website builder or a print workflow asks for PNG, and that is when a quick converter helps.
The PromptCraft Studio JPG to PNG Converter does the conversion inside your own browser. There is nothing to install, no account to create and no upload to a server. Add your files, wait a moment, and download the PNG versions.
Why convert JPG to PNG?
- Editing without more quality loss: Every time you save a JPG, the format compresses it again and adds small artifacts. If you plan to edit an image several times, working with a PNG copy stops that repeated loss.
- Sharp text and graphics: Screenshots, logos, charts and UI mockups look cleaner as PNG because edges are not blurred by JPG compression.
- Compatibility: Some apps, templates and upload forms only accept PNG. Converting is faster than asking for a different file.
- A good starting point for transparency: PNG can store transparent areas, so it is the format you want before you remove a background in an editor.

How to convert JPG to PNG
- Add your files: Drag your JPG files onto the upload area, or click it to browse. On a phone or tablet, tap the area and choose photos from your gallery.
- Wait for the conversion: Each image is converted straight away. You will see a preview with the original size and the new PNG size.
- Download: Press Download PNG on a single file, or Download all to save every converted image.
- Remove what you do not need: Use the × button on a row, or Clear to start again.
Your photos stay on your device
Many online converters upload your images to a remote server. This one does not. The conversion runs locally in your browser using the built-in HTML5 canvas, so your photos are never sent anywhere. That makes it a sensible choice for personal pictures, ID scans and client work.
What to expect from the result
Converting a JPG to PNG does not bring back detail that was already lost when the JPG was created, and it does not add transparency by itself. The PNG will look the same as the JPG, but it will be stored without any further compression loss. Because PNG uses lossless compression, the new file is often several times bigger than the original photo. If file size matters more than anything else, keep the image as JPG.
Frequently Asked Questions (FAQ)
Is this JPG to PNG converter really free?
Yes. There are no limits on the number of conversions, no watermarks and no registration.
Does the converter upload my images?
No. Everything happens in your browser. Your images are not uploaded to any server, and they disappear when you close or refresh the page.
Why is the PNG bigger than my JPG?
JPG throws away some detail to save space, while PNG keeps every pixel exactly as it is. That is why PNG files are usually larger, particularly for photographs.
Will the PNG have a transparent background?
No. A JPG has no transparency, so the converted PNG keeps the same solid background. To make the background transparent you need to remove it in an image editor afterwards.
Can I convert several JPG files at once?
Yes. Select or drop as many files as you like. Each one appears in the list with its own download button, and Download all saves them one after another.
Does it work on my phone?
Yes. The tool is built for phones, tablets and desktop browsers. On mobile, tap the upload area and pick photos from your gallery or camera roll.
Are very large photos supported?
Most photos work fine. Extremely large images, for example very high-resolution panoramas, may fail on older phones because browsers limit the canvas size. If that happens, try a desktop browser.
