Ready settings for your image
PNG is useful for logos, screenshots and graphics with transparent areas. The tool creates a PNG and preserves existing transparency.
Images with a side longer than 4,000 pixels are resized proportionally to fit within 4,000 pixels. For a specific file-size limit, use a KB tool.
File sizes use decimal units: 1 KB = 1,000 bytes and 1 MB = 1,000 KB. Your image is processed on your device.

JPG to PNG: when PNG is the better format
PNG suits logos, screenshots, diagrams and graphics with sharp edges, because it stores the image without lossy compression. Converting a JPG to PNG helps when a design tool, website template or document needs a PNG file. It cannot restore detail that the JPG has already lost.
Because PNG is lossless, the file is often larger than a JPG of the same picture. If you need a small file for a form or an email, use a KB page or a JPG page instead. This page does not target a size limit.
If the image will only appear on a web page and does not need transparency, a JPG may be lighter. This page is the right choice when you need PNG specifically.
Keeping edges crisp
Start from the cleanest source you can get. A JPG that has been compressed many times can show blocky edges, and converting it to PNG keeps those artifacts rather than removing them. A screenshot or a higher-resolution original gives a cleaner PNG.
Images with a side over 4,000 pixels are scaled down proportionally to fit within that size, and the shape stays the same. Review the preview at full size before you download, especially for text and thin lines.
Logos saved as PNG keep hard edges, which is the main reason to choose PNG for them.
Convert on a phone or computer, privately
Open the page on a phone or computer, choose the JPG and download the PNG. Processing happens on your device, the image is not uploaded to a server and no account is needed. The downloaded file has no watermark.
Sizes are decimal, so 1 KB equals 1,000 bytes. You can compare the output with other files you have.
Use the preview at full size to check that the converted file matches the source, especially where colors or edges matter.
To convert image to PNG here, choose your JPG, then select Convert to PNG. PNG is already selected, so after you pick the file, two clicks are enough: convert, then download the new file. The converted file is made on your device, and the preview lets you check it before you download.
Frequently asked questions
Is converting to PNG free?
Yes. The converter is free, needs no sign-up, and the downloaded PNG has no watermark.
When is PNG useful?
PNG works well for logos, screenshots and graphics. It stores the image without lossy compression and keeps transparent areas that already exist in the source.
Will converting to PNG make the file smaller?
Usually not. PNG is lossless, so the file is often larger than a JPG of the same picture.
How can I convert a JPG image to PNG?
Choose the JPG and select Convert to PNG. The free browser-based converter creates the file on your device.
Does converting change the picture?
The conversion keeps the image content. Check the preview at full size for any change in color or edges before you use the file.
Can I convert a JPG to PNG without uploading it?
Yes. Processing happens on your device, the image is not uploaded to a server, and no account is needed.
How do I change a JPG extension to PNG?
Use the converter instead of renaming the file. It creates a new PNG file, while renaming a .jpg only changes the label and leaves the image as a JPG.
