PNG to JPG Converter

PNG and JPG were built for different jobs. PNG (Portable Network Graphics) is a lossless format that keeps every pixel exactly as it was saved, and it supports transparency. That makes it ideal for logos, screenshots, icons and any graphic with sharp edges or text. The downside is file size: a photographic PNG can easily be three to ten times larger than the same picture saved as JPG.

JPG (also written JPEG) uses lossy compression tuned for photographs. It discards detail your eye barely notices in exchange for dramatically smaller files. When you convert a PNG photo to JPG you typically cut the file size by 70–90% with no visible difference, which is why almost every website, email attachment and upload form prefers JPG for photos.

The most common reason people convert PNG to JPG is an upload limit. Job portals, government forms, exam registrations and image hosts often cap files at a few megabytes, and a high-resolution PNG screenshot or photo blows straight past that. Converting to JPG is the fastest way to fit under the limit without resizing.

This converter never uploads your file. When you drop a PNG in, your browser decodes it into a canvas — a grid of pixels held in memory — and then re-encodes that canvas as a JPG using the same JPEG algorithm built into Chrome, Firefox, Safari and Edge. The finished JPG is handed back to you as a download. Your image never touches a server, which is why it works on locked-down office computers and why your private screenshots stay private.

Because JPG has no transparency, any transparent areas in your PNG are flattened onto a solid background (white by default). If your PNG is a logo on a transparent background and you need to keep that transparency, convert to WebP instead, which supports both transparency and strong compression.

Keep the original PNG if the image is a logo, diagram or screenshot with text — JPG compression adds faint 'mosquito' artifacts around hard edges, while photos hide those artifacts well. Convert photographs freely; keep graphics as PNG or WebP.

If your goal is a specific file size (for example 'under 200 KB for a visa form'), use a compress-to-size tool rather than a plain converter, because it will lower the JPG quality automatically until the file fits.

JPG does not store layers, so a converted file is final and flat. That is exactly what upload forms want, but keep a copy of the editable original if you might need to change it later.
