Compress Image to 50KB
Automatically tunes quality until your JPG, PNG, or WebP fits under 50KB - free and entirely in your browser.
50KB is a sweet spot for images embedded in emails and newsletter templates, where heavy images trigger clipping in Gmail and slow opens on mobile. It also suits web thumbnails and card images that appear a dozen at a time on a page. Most photos reach 50KB with moderate quality reduction once oversized dimensions are trimmed.

Frequently asked questions
Why do email images need to be this small?
Gmail clips messages over 102KB of HTML, and slow-loading embedded images hurt engagement on mobile connections. Keeping each image near 50KB keeps the whole email fast and intact.
Will 50KB be enough for a sharp thumbnail?
Yes - at typical thumbnail sizes (300-600px wide), 50KB leaves plenty of quality headroom. It's full-screen images where 50KB starts to show visible compression.
