Loading Snapframe…
Mark up any screenshot right in your browser. Point with arrows, frame regions with boxes, add text labels and sweep highlights — all in any colour — then frame, blur and export. Your images never leave your device.
Four annotation tools, a full colour palette, and the rest of the editor to make it presentable.
Drop a clean arrow to point straight at the bug, the button or the line that matters. Reposition and recolour until it lands.
Draw a box around the exact region you mean. Perfect for circling an error state or isolating one part of a busy UI.
Type captions, step numbers or notes directly on the image so reviewers know what they're looking at without a separate message.
Sweep a translucent highlight over a row, field or paragraph to draw the eye where it needs to go.
Pick any colour for each arrow, box, label or highlight — red for problems, green for fixes, your brand colour for docs.
Pair markup with drag-to-blur and auto-redact (OCR) so emails, tokens and names are hidden before the screenshot leaves your screen.
Paste from the clipboard or drag a file into the editor. It loads instantly in your browser — nothing is uploaded to a server.
Pick a tool, click and drag to place it, then choose a colour. Layer as many annotations as you need and nudge them into place.
Add padding, a window frame and a background if you like, blur anything sensitive, then export PNG, JPG or WEBP up to 4K with Pro.
A red arrow on the broken button, a box around the error, a text label with the steps to reproduce — that's a bug report a teammate can act on in seconds. The same tools turn raw captures into clear tutorial steps and review comments.
Because Snapframe also handles backgrounds, frames and shadows, your annotated shots look at home in docs and help articles — not like a quick scribble. And when a screenshot contains an email, an API key or a customer name, drag-to-blur and auto-redact let you hide it before you share, all without anything leaving your browser.
Most markup tools stop at arrows. Snapframe adds backgrounds, Mac & browser frames, shadows, filters and crop — so an annotated screenshot also looks polished for docs and tutorials.
Everything runs locally in your browser. Your screenshots and the things you annotate never leave your device, which matters for bug reports full of internal data.
Open the editor and annotate right away — no account. Pro is a one-time $12 (no subscription) that removes a small watermark and unlocks 4K export.
Arrows, boxes, text and highlights in any colour — free, private and right in your browser. No signup, no upload.
