JPG to PNG
JPG is great for photos but uses lossy compression. PNG stores images losslessly and supports transparency, so it is better for screenshots, logos and further editing. The conversion runs locally in your browser.
The image is converted in your browser — the file is not uploaded.

More about JPG to PNG
Why convert JPG to PNG
JPG uses lossy compression: every time you open and save the file, some detail can be lost. PNG stores the image losslessly, which makes it convenient for further editing, text overlays and preparing graphics for a website.
The conversion is especially useful if you need to:
- keep a screenshot free of compression artefacts;
- prepare an image for an editor that works with PNG;
- avoid repeated compression during several editing steps;
- get a file that supports transparency for later processing.
How it works
The tool opens the JPG in your browser, draws it on a hidden canvas and exports the result as PNG. No data is sent over the network. If the browser cannot decode the file, the conversion continues on the server with sharp, and the result is deleted after download.
What to know
PNG usually takes more space than JPG because it stores the image losslessly. For web publishing, heavy PNG files should be compressed further or converted to WebP. For print and archiving, PNG remains a convenient choice.
Questions and answers
Does converting JPG to PNG improve quality?
No. PNG does not add detail, but it preserves the existing image without further lossy compression.
Is the file uploaded to a server?
No. The image is decoded and re-encoded by your browser using the Canvas API, so the file never leaves your device.
Why is the PNG larger than the JPG?
PNG stores image data losslessly, so the file is usually larger. For websites, consider converting to WebP instead.
What is the maximum file size?
Up to 25 MB per image. For larger files, resize the image or use a desktop editor.
