About JPEG to PNG conversion
This free JPEG to PNG converter runs entirely inside your browser using the HTML5 Canvas API. Nothing is uploaded to a server, so it is safe for private photos, client work and sensitive documents. You can convert one file or hundreds at once, resize them and fine-tune quality before downloading.
PNG is a lossless format that supports full transparency, ideal for logos, screenshots, UI assets and text-heavy graphics.
JPEG is a lossy format built for photographs: small files, but no transparency and visible artifacts at low quality.

Frequently Asked Questions
How do I convert JPEG to PNG for free?
Open this page, drop your JPEG images into the box, make sure the output format is set to PNG, then click Convert. The conversion happens instantly in your browser and you can download each PNG file or all of them at once โ completely free with no account and no watermark.
Is it safe to convert JPEG to PNG online?
Yes. This tool never uploads your images. The decoding and re-encoding is performed locally by JavaScript and the Canvas API inside your browser, so your files stay on your device. There is no server storage, no logging and no third party involved.
Does converting JPEG to PNG reduce quality?
Converting to a lossless format such as PNG keeps every pixel intact. Converting to a lossy format such as WebP or AVIF discards a small amount of data controlled by the quality slider; at 80-90% the difference is usually invisible while files shrink dramatically. Note that detail already lost in the original JPEG file cannot be recovered.
Will the PNG file be smaller than the original JPEG?
It depends on the formats and settings. WebP and AVIF usually produce files 25-50% smaller than JPEG at similar quality, while lossless PNG is often larger than a JPEG of the same image. Use the quality slider and the max width option to control the final size, and check the savings shown next to each converted file.
