JPEG to PNG Converter
Convert a JPEG or any browser-readable image to a lossless .png file.
Drag & drop a photo here, or click to browse
JPEG, PNG, or WebP
Sometimes you need the opposite of a JPEG — a PNG that supports transparency, or simply a format that doesn't introduce the soft compression artifacts JPEG leaves around sharp edges and text. Logos, screenshots, diagrams, and graphics with flat colors usually look noticeably cleaner as PNG, and many design tools, presentation software, and websites expect PNG specifically when an image needs a transparent background. This tool takes any JPEG (or other image format your browser can open) and re-encodes it as a lossless PNG, decoded and redrawn entirely through the Canvas API in your browser. Since PNG is lossless, no additional compression artifacts are introduced during this step — the main tradeoff is file size, since PNG files are typically larger than an equivalent JPEG for photographic content. Nothing you upload here ever leaves your device; the whole conversion runs locally and the result downloads directly to your computer.
How it works
- 1
Drop or select a JPEG (or any image your browser can open).
- 2
We decode it and redraw it losslessly onto a canvas as PNG.
- 3
Download the resulting .png file.
Frequently asked questions
Will my JPEG artifacts disappear if I convert to PNG?
No — PNG can't remove compression artifacts already baked into a JPEG's pixels, since those changes happened when the JPEG was first saved. Converting afterward just stops any further compression from being added.
Why is my PNG file bigger than the original JPEG?
PNG is a lossless format, so it stores more detail per pixel than JPEG's compressed encoding — that's normal and expected, especially for photos rather than flat-color graphics.
Does PNG support transparency from my original image?
Yes — if your source image already has an alpha channel (like a PNG or WebP with transparency), it is preserved. JPEG source images have no transparency to begin with, so the PNG output will be fully opaque.
