Convert Screenshots to JPG

Screenshots on macOS, Windows, and most Linux desktops are saved as PNG by default. PNG is lossless, which means the files are large: a full-screen screenshot at 1440p is easily 2 to 5 MB. That’s fine for archiving but painful when you need to paste it into an email, upload it to a form with a 1 MB limit, or share a dozen screenshots in a Slack thread.

Drop a screenshot below. Your browser converts it to JPG, typically shrinking it by 5 to 10 times.

The conversion runs in your browser. The file never leaves your computer. No signup, no upload, no tracking.

When JPG is the right choice for screenshots

JPG works well for screenshots of web pages, apps, dashboards, and anything with gradients or photos in it. The lossy compression introduces minor artifacts, but at 90% quality or above they are invisible in normal viewing.

JPG is not ideal for screenshots of code, terminal output, or pixel-art-style interfaces. The compression can blur sharp single-pixel edges and make text slightly fuzzy. For those cases, PNG to WebP is a better option: WebP compresses well and preserves sharp edges.

How much smaller will it be?

It depends on the content. Screenshots with large areas of solid color (like a mostly-white document) compress extremely well and can shrink by 10x or more. Screenshots of complex UIs or photos-within-screenshots compress less aggressively, typically 3 to 5x.

The file size comparison shown after conversion tells you exactly how much space was saved. Use the quality slider to find the balance point for your use case.

Retina and HiDPI screenshots

Retina displays capture screenshots at 2x resolution, so a screenshot of a 1440×900 screen is actually 2880×1800 pixels. These files are even larger as PNG (often 5 to 10 MB) and benefit even more from JPG compression. The converted JPG keeps the full resolution, just at a smaller file size.
