Free PNG to JPG Converter
Convert PNG images to JPG format. Reduce file size and adjust quality — all in your browser.
PNG to JPG conversion reduces file size significantly — often 60-80% smaller for photographic content. JPG is the universal format accepted by every application, platform and device. Note that JPG does not support transparency: transparent areas in the PNG will be filled with white in the output. Conversion runs in your browser using the Canvas API with no upload.

PNG, APNG supported · Multiple files · No limitsBefore converting, consider whether you actually need to. If your PNG is a photograph, JPG will reduce its size significantly with minimal visible quality loss. If your PNG is a logo, illustration or screenshot with text, keeping it as PNG preserves sharpness. JPG compression can cause visible artefacts around sharp edges and text in non-photographic content.
When to Convert PNG to JPG?
The quality setting is the decision that matters. This converter starts at 90% and lets you move it between 50 and 100. Ninety is where the artefacts stop being visible on a photograph while the file is a fraction of the PNG. Below about 75% the damage shows on smooth gradients — skies, skin, out-of-focus backgrounds — as faint blocky banding that no later step can remove.
PNG files use lossless compression which keeps every pixel detail — great for logos and screenshots, but can make photos unnecessarily large. JPG uses lossy compression that reduces file size dramatically while maintaining good visual quality for photographs.
What Happens to Transparency, and When the Trade Is Worth It
JPEG has no alpha channel. There is no way to express "this pixel is transparent" in the format, so every transparent area must be resolved to an actual colour before encoding. This tool fills the canvas with white and draws the image on top, so transparent regions become white and partially transparent pixels blend proportionally toward white.
That is the right default for most cases and a poor one for a specific case: a logo with soft, anti-aliased edges designed to sit on a dark background. Its semi-transparent edge pixels blend toward white and the logo ends up fringed with a pale halo that looks like a badly cut-out sticker. If the destination background is not white or near-white, keep the PNG.
Where the trade pays off is photographic content. A photograph saved as PNG is typically three to five times larger than a visually equivalent JPEG, because DEFLATE cannot exploit the perceptual redundancy that JPEG's frequency-domain approach targets. Converting a photo-heavy page from PNG to JPEG is often the single largest page-weight saving available, at a quality difference most viewers cannot detect. Reserve PNG for what it is good at — screenshots, diagrams, line art, anything with sharp edges, flat colour or genuine transparency.
