About Screenshot Editor
Most screenshot tools do one job. The Screenshot Editor does the whole job on one canvas, so you never download from one tool and re-upload into the next. Crop to an exact aspect, resize for the web or an app store, drop in arrows, boxes and text, blur or pixelate anything sensitive, then pad the shot with a solid or gradient background and wrap it in a phone, tablet, laptop or monitor frame. Everything runs in your browser at the screenshot's native resolution — nothing is uploaded. The focused tools below still exist for fast single-job edits.

How it works
- 1
Drop or paste a screenshot
JPG, PNG or WebP up to 50 MB, or paste straight from the clipboard. It decodes at full resolution, so nothing is downscaled until you choose to resize.
- 2
Crop, resize, mark up
Drag a crop box with aspect presets, set an exact output size, then add arrows, highlights and text and blur or black-bar private details.
- 3
Pad, frame and export
Add padding with a solid or gradient background and an optional device frame, then export a PNG or JPG. No watermark, no sign-up.
The edit that happens between the screenshot and the send
A raw screenshot is rarely what you meant to send. It's the whole screen when you meant one panel, it has your other tabs in it, and the thing you're pointing at isn't obviously the thing you're pointing at. The gap between taking a screenshot and it being useful is about thirty seconds of cropping, an arrow, and covering the one thing that shouldn't be in frame.
That's what this is for — the short edit that turns a capture into a communication.
Marking up so the reader sees what you see
- Crop first, always. Removing everything irrelevant does more for clarity than any annotation, and it's the step people skip.
- One arrow beats three. If you need three, you probably need two screenshots.
- Boxes for regions, arrows for points. A box around a button says 'this area'; an arrow says 'this exact thing'.
- High-contrast colour. Red and yellow survive being viewed on a phone in daylight; a subtle grey annotation may as well not be there.
- Text sparingly. If the explanation doesn't fit in four words, it belongs in the message, not burned into the picture.
Hiding things properly
A black box over an account number is safe. A blur over it may not be — blurring is a mathematical transform, and a weak one applied to a known font can sometimes be reversed well enough to read. Pixelation has the same weakness. Neither is a redaction; both are an obfuscation that looks like one.
For anything that genuinely matters — account numbers, addresses, tokens, faces — draw an opaque shape over it. The full reasoning, and the tool built for it, is in Blur Sensitive Info.
Why it matters that this runs locally
Screenshots are, by their nature, pictures of whatever was on your screen — your inbox, your dashboard, your client's data, your bank. Uploading one to an editing site to draw an arrow on it means handing that to someone else's server.
Everything here happens in the tab on a canvas. The image is read from your clipboard or your disk, edited in memory, and downloaded. No upload, no account, no copy anywhere but yours.
Frequently asked questions about Screenshot Editor
How is this different from the Screenshot Annotator?
The Annotator only draws arrows, boxes and text on an image at its original size. The Editor adds crop and resize — which no other screenshot tool here does — and bundles annotation, blur, background and device framing into one pipeline so you never switch tools mid-edit.
Can I crop to a specific aspect ratio?
Yes. Free, 1:1, 16:9, 4:3 and 9:16 presets plus a numeric output size. Crop and resize run before the frame stage, so the framed result always uses your cropped, resized image.
Will resizing or blurring reduce quality?
Downscaling uses high-quality smoothing, so text stays crisp. For redaction prefer mosaic or a solid bar — a light Gaussian blur can sometimes be partially reversed.
