Shrink a screenshot so you can email it
A full-screen PNG from macOS or Windows can be 8–20 MB. Gmail and many ticket systems choke. Convert it to JPG in this tab, optionally cap the width, and attach the result.

JPG, PNG, WebP, GIF, SVG, or HEIC. Your photos stay on this device.
When to use this
Choose JPG when the screenshot is a photograph of a window you need to send, not a pixel-perfect UI spec. 0.85 is sharp enough for most bug reports.
Keep PNG if the capture is a diagram, lots of small text, or a design review where JPG fuzz around small type would be annoying.
If a form says “max 2 MB,” skip guessing quality and use the upload limit tool. It searches quality and width for you.
Several captures that should read as one document belong in a PDF. That is a different job: JPG to PDF on ❤️ LoveThisPDF, also in the browser.
How to do it
- Drop the PNG screenshot.
- Leave output on JPG, quality around 0.85, max width 1920.
- Check the new size on the file row. If it is still large, drop width to 1280.
- Download and attach.
Tips
- Retina screenshots are 2× the CSS pixels. You rarely need that for email.
- Red squiggles and arrows survive JPG at 0.85. Tiny 9px labels might not.
- Do not convert a logo with a transparent hole to JPG unless a white fill is OK.

FAQ
- Why is my PNG so big in the first place?
- PNG stores every pixel losslessly. A 4K screen capture is millions of pixels with almost no compression win on photo-like areas.
- Will Gmail still compress it?
- Sometimes. Sending a 1920px JPG still avoids the “attachment too large” bounce.
- Is the screenshot uploaded to convert it?
- No. It is encoded in your browser.
