JIEZO: Free Screenshot Editor and Mockup Maker

JIEZO is a free, open-source screenshot editor that runs entirely in your browser. Drop in a screenshot and turn it into a professional graphic: add a gradient background, wrap it in a Safari or Chrome browser mockup, tune the padding, corner radius, and shadow, tilt it in 3D, then export a PNG, JPEG, WebP, MP4, WebM, or GIF. Editing runs on your device and imported images are not uploaded to edit them; only export compression sends the finished image to the server, which returns it without storing it. There is no signup, no watermark, and no paid tier, which makes it a free alternative to Pika Style, Shots.so, Screely, and CleanShot X.

What you can do here

• 100+ gradient, mesh, and pattern backgrounds
• Safari, Chrome, and Arc browser mockups in light and dark mode
• macOS window chrome, Polaroid, glass, outline, and border device frames
• 3D perspective transforms with fully configurable shadows
• 20+ animation presets driven by a keyframe timeline editor
• Video export to MP4, WebM, and GIF, encoded in the browser with FFmpeg WASM
• Text and image overlays with 27+ Google Fonts
• Tweet-to-image and code-snippet-to-image capture
• High-resolution PNG, JPEG, and WebP export up to 5x scale

Who it is for

Developers polishing README, changelog, and documentation images; marketers building launch graphics and social posts; and designers presenting work without leaving the browser. JIEZO is available in English, Spanish, French, German, Japanese, Portuguese, Korean, and Chinese.
