How do I convert JPEG to PNG for free?

Drop your JPEG files into the converter above, select PNG as the output format, click Convert All, then download each file. No upload — conversion runs entirely in your browser.

What is the difference between JPEG, PNG, and WebP?

JPEG uses lossy compression — smallest file size, best for photos. PNG is lossless — larger files but no quality loss, best for screenshots and graphics. WebP is a modern format that is 25-35% smaller than JPEG at the same quality and supports transparency like PNG.

Can I convert multiple images at once?

Yes. Drop multiple files at once, click Convert All, then download them individually or as a single ZIP file. There is no limit on the number of files.

JPEG vs PNG vs WebP — Which Image Format Should You Use?

Choosing the right image format can significantly reduce file sizes, improve website load times, and preserve image quality. Here is a quick guide to the three most common formats:

JPEG (Joint Photographic Experts Group)

Best for: Photographs, scanned images, social media uploads.

JPEG uses lossy compression, which means some image data is discarded during encoding to achieve small file sizes. At quality 85–95%, the loss is barely visible. JPEG does not support transparency. It is the most widely supported format across all platforms and devices. Use JPEG when you need the smallest possible file size for a photo.

PNG (Portable Network Graphics)

Best for: Screenshots, logos, graphics with text, images requiring transparency.

PNG uses lossless compression — no image data is lost during encoding. This means larger files than JPEG, but pixel-perfect quality. PNG supports full transparency (alpha channel), making it essential for logos and UI graphics. For photographs, PNG files are typically 5–10× larger than an equivalent JPEG.

WebP

Best for: Web images, modern apps, anywhere you need JPEG-like quality with PNG-like flexibility.

WebP was developed by Google as a superior replacement for both JPEG and PNG. Lossy WebP is typically 25–35% smaller than JPEG at equivalent quality. Lossless WebP is typically 26% smaller than PNG. WebP also supports transparency. It is now supported by all major browsers (Chrome, Firefox, Safari, Edge). Converting your images to WebP is one of the easiest ways to speed up a website.

When to Convert Image Formats

JPEG → PNG: When you need to preserve full quality and transparency support for editing or compositing.
PNG → WebP: When you want to reduce file size for web use without any visible quality loss.
JPEG → WebP: When you want the same photo quality at 25–35% smaller file size for faster page loads.
PNG → JPEG: When you need the smallest file size and the image has no transparency.
