Screenshot Studio in your browser, no signup

A full screenshot maker and editor that runs entirely in your browser. Capture a screen, window or tab at the display's native resolution (including Retina / high-DPI), select any region with a CleanShot-style overlay, then annotate with arrows, shapes, text, blur, spotlight and filters. Copy the finished image straight to the clipboard for WhatsApp, Slack, Teams, Figma and more - or download PNG, JPG, WEBP or PDF. Nothing is uploaded to a server.

Most people open this because a photo is too big, in the wrong format, or they do not want to install an editor for a two-minute job.

Screenshot Studio is a good fit when marking up a bug report with red arrows, numbered steps and callouts.

In plain English

Screenshot Studio is built around a few practical wins, not a long feature list:

• Native-resolution capture with DPR-aware cropping - no soft or blurry exports on Retina displays.
• Professional markup tools: pens, arrows, shapes, speech bubbles, text with many fonts, stickers and highlight effects.
• Screenshot library with search, favorites, rename, duplicate and reorder - kept in memory on your device.
• One-click clipboard copy that pastes into WhatsApp, Discord, Slack, Teams, Word, PowerPoint, Figma and more.
• Bonus utilities: OCR text extraction, QR detection, face-region blur assist and AI background removal.
• Runs locally - captures and edits never leave your browser. Free, no account, no watermark.

How to run it

1. Take a screenshot. Click Take Screenshot, pick a screen, window or tab when the browser asks, then drag to select a region. Enter or double-click confirms; Esc cancels. You can also upload, paste (Ctrl+V) or drop an image.
2. Annotate in the editor. Draw freehand, add arrows and shapes, place text in many fonts, stickers, blur or pixelate regions, spotlight focus areas, and tune filters. Zoom, pan, undo/redo and layers work like a design tool.
3. Copy or export. Copy puts a pixel-perfect PNG on the system clipboard so you can paste anywhere. Export supports PNG, JPG, WEBP and PDF with scale (1×–3×), quality and transparency options.

Real situations

• Marking up a bug report with red arrows, numbered steps and callouts.
• Capturing a UI and adding a caption before sharing in Slack, Teams or Discord.
• Blurring faces or sensitive data before posting a screenshot publicly.
• Building a quick tutorial with stickers, highlight boxes and focus/spotlight.
• Exporting a polished PNG or PDF of an annotated screen for docs or tickets.
• Copying an edited screenshot to paste straight into WhatsApp or email without downloading.

Small habits that help

• Prefer “Entire screen” or a specific window in the browser picker for the sharpest frame.
• Hold Shift while drawing lines and arrows to keep them straight.
• Spacebar temporarily pans the canvas; Ctrl+Z / Ctrl+Shift+Z undo and redo.
• Use Copy when you want to paste immediately - no download required.
• OCR and background removal download models on first use, then cache locally.

Skip these

• Expecting capture without the browser permission prompt - you must choose a screen or window each time.
• Saving JPG when you need transparency after background removal - use PNG instead.
• Drawing tiny selections that crop to almost nothing; aim for at least a few pixels.
• Assuming face blur is a certified face detector - it is a privacy assist based on skin-tone regions.
• Closing the tab mid-edit and expecting the in-memory library to survive - session storage is in-memory only.

Does anything leave your device?

Screenshot Studio runs in your browser. The file or text you paste stays on your device. There is no account, and nothing is stored on a ToolBox server for this job.
