Convert JPG to PNG

Converting JPG to PNG makes sense when a file needs lossless quality, transparency support, or future-proof editing. JPG is a lossy format built for photographs — every save discards detail and every JPG lacks an alpha channel, so it can never store a transparent background. PNG is lossless: pixels are preserved exactly as decoded, which is why logos, screenshots, UI mockups, and text-heavy images are better archived as PNG. This converter decodes your JPG in the browser via the Canvas API and re-encodes it to PNG without recompression artifacts — since the source JPG's losses are already baked in, converting to PNG loses nothing further and stops the quality death-spiral of repeated JPG saves. A frequent companion need is removing the background entirely: a JPG's white background can be erased with an AI background remover and then saved as a true transparent PNG. Note that converting JPG to PNG usually increases file size — PNG stores more information, and that trade is exactly the point when editability matters more than bytes.

• 1PNG is lossless — converting once stops the generational quality loss that happens every time a JPG is re-saved by an editor or platform.
• 2PNG supports full 8-bit alpha transparency. JPG physically cannot store transparency, so any cutout or overlay workflow starts by converting to PNG.
• 3Screenshots, UI captures, and text-heavy images survive PNG conversion without the ringing artifacts JPEG bakes into sharp edges.
• 4Everything runs locally via Canvas — confidential designs, unreleased brand work, and personal photos never touch a server.
• 5Unlimited and free: no sign-up, no daily quota, no watermark on the output file.
• 6Works everywhere — Windows, macOS, Linux, iOS Safari, and Android Chrome all decode and re-encode natively.
