Use Cases
Drop in a screenshot, drag a blur box over the parts no one should see, and export a clean copy in seconds. Hide emails, API keys, and customer data, or flip to spotlight mode and blur everything except the one thing you want people to look at. Free, in your browser, no signup needed to edit.

The email gets blurred, the API key gets inked over, and every other pixel stays sharp: the same treatments the editor applies to your screenshot.
The Annotate palette in the free editor covers both jobs a blur tool gets asked to do: hiding what should not be seen and highlighting what should.
Drag a rectangle over an email address, a customer name, or a revenue number and everything inside it turns unreadable. Add as many regions as the screenshot needs and resize each one independently.
Blur part of a screenshotThe same tool, flipped. Everything outside your box softens while the selected area stays crisp, which pulls every eye straight to the button, setting, or error you are pointing at.
Try spotlight modeA blur can sometimes be reversed with enough effort; a solid ink bar cannot. For API keys, passwords, tokens, and account numbers, the Redact tool paints over the pixels entirely, so the export contains nothing to recover.
Redact a screenshotThe same palette includes arrows, a highlighter, and numbered step badges, so the screenshot that hides your secrets can also walk a reader through a flow. One pass, one export.
Annotate a screenshotMost screenshots are fine to share except for one small rectangle. A support reply with a customer's email in the corner. A dashboard with real revenue in the header. A terminal with an API key three lines up from the part you actually care about. Cropping throws away the context; re-taking the screenshot with fake data takes ten minutes you do not have.
Blurring just that rectangle is the honest middle: the reader still sees a real screen, and the sensitive part is gone. In Screenhance you drop the screenshot into the screenshot editor, open the Annotate palette, and drag a blur region over each area to hide. Regions are independent elements, so blurring five scattered spots is no harder than blurring one, and you can nudge or resize any of them until the export looks right.
The same palette handles the rest of the markup: arrows to point, a highlighter to underline, numbered badges to sequence steps. If your screenshot needs more explaining than hiding, the screenshot annotation tool page walks through that side of the palette.
Here is the honest part most blur tools skip: blur is obfuscation, not deletion. A blur filter averages the pixels in a region, and with enough effort, especially on light blurs over known fonts at known sizes, that averaging can sometimes be run backwards far enough to guess the original text. For a name in a busy table, that risk is theoretical. For an API key that grants access to your production database, theoretical is not good enough.
That is why the Annotate palette includes a solid Redact bar alongside the blur tool. Redaction does not soften the pixels; it replaces them with opaque ink, and when you export, the flattened image simply does not contain the covered data. There is no filter to reverse because there is nothing underneath.
A simple rule of thumb: blur what you would rather people not read, redact what people must never recover. Blur the customer names, the face in the video call, the notification popup. Redact the API keys, the passwords, the tokens, the account and card numbers. Both tools live side by side in the editor, so applying that rule takes seconds, not a second tool.

Two capabilities that separate Screenhance from every other mockup tool in 2026: animated exports and App Store screenshot localization.
Template-driven motion — float, reveal, parallax. Export animated mockups at Product Hunt, landing-page, and Twitter/X dimensions. Most mockup tools are static-only.
One master design, per-locale captions, every required Apple and Google Play size per language. RTL and CJK support. Apple reports localized listings drive 2-3x install lifts.
iPhone 17 Pro Max (1320×2868), iPhone Air (1260×2736), iPad Pro M4 (2064×2752), and the full Google Play set — exported from one design in a single pass.
Pick a template, drop in your screenshot, export. No Figma, no Photoshop, no learning curve. Free tier covers 3 exports a month; $6 Week Pass unlocks unlimited for a launch.
Once a blur tool is in your hands, a second use appears: instead of hiding one region, blur everything else. Spotlight mode inverts the blur so the box you draw stays sharp while the rest of the screen softens. It is the fastest way to say "look here" in a tutorial step, a changelog image, or a bug report, because the reader keeps the full screen for context but cannot help focusing on the part you selected.
And since the blur lives inside a full editor rather than a single-purpose widget, the screenshot does not have to stop at hidden. Put it on a clean background, wrap it in a browser or device frame, and it goes from "sanitized evidence" to something you would happily post. The screenshot beautifier covers that finishing pass. Exports come out as PNG, WebP, or JPEG, and the free plan includes 3 exports per month with a subtle watermark, with no account needed until the moment you export.
Mostly, with one honest caveat. A strong blur makes text unreadable to anyone glancing at the image, and that is enough for most emails, names, and faces. But blur works by mathematically smearing pixels, and researchers have shown that light blurs over known fonts can sometimes be reconstructed with enough effort. For data where any chance of recovery is unacceptable, such as API keys, passwords, or account numbers, use the Redact tool instead: it covers the area with solid ink, so there is nothing underneath to recover in the exported file.
Blur softens the pixels in an area so it becomes unreadable but still visibly present; you can tell a table cell or a name field exists, you just cannot read it. Redact paints a solid opaque bar over the area, completely replacing what was there. Blur reads as polite and keeps the screenshot looking natural, while redaction is the safer choice for credentials and anything truly confidential. Screenhance puts both in the same Annotate palette, so you can blur a customer name and redact an API key in the same pass.
Yes. The editor opens straight from this page with no account: drop your screenshot in, add blur regions or redact bars, and see exactly how the result looks. You only create an account at the moment you export, and the free plan includes 3 exports per month with a subtle watermark.
Yes. Each blur region is its own element on the canvas, so you can add as many as the screenshot needs, one over an email address, another over a chart, a third over a sidebar, and move or resize each independently. You can also mix tools: blur regions for some areas, solid redact bars for others, and arrows or numbered step badges on top.
Spotlight is the Blur tool flipped inside out. Instead of blurring inside the box you draw, it blurs everything outside it, so the region you select stays sharp while the rest of the screen softens. It is a fast way to direct attention in a tutorial, a bug report, or a feature announcement: readers see the whole screen for context but their eyes land exactly where you pointed.
PNG, WebP, and JPEG. PNG keeps text and UI edges crisp and is the safe default for documentation. WebP gives you smaller files at similar quality for the web, and JPEG is there when a tool in your workflow demands it. Whichever format you pick, the blur and redact marks are flattened into the image itself, not stored as removable layers.
