ScreenArt Pro vs Lightshot: the free screenshot tool that uploads everything, and the one that uploads nothing

Why this comparison is about one feature

Lightshot is simple, and that is why millions of people have it. Press PrtSc, drag a region, click the cloud icon, and a short link is on your clipboard. Paste it into a chat and you are done. It is free, it runs on Windows and Mac and as a browser extension, and the editor has enough to draw an arrow.

The cloud icon is the whole design, and it is the reason this article exists. Every upload goes to prnt.sc and comes back as a short public URL. There is no login on the other end. Anyone who has the link can open the image. The IDs are short, and for years people have shown that you can walk through them and see what strangers uploaded: pay slips, passports, chat logs, admin consoles, credentials. None of that is a bug in Lightshot; it is how a short public link works.

ScreenArt Pro is the opposite design: nothing is uploaded, ever, and the secrets are found and covered before the file exists. This article compares the two honestly, including what Lightshot still does well, but it starts with the one feature that matters most.

Lightshot’s features were read from its own site in October 2026.

What Lightshot does well

• It is fast. PrtSc, drag, done. The capture overlay is one of the quickest there is.
• It is free and runs on both desktop platforms and in a browser.
• The link is instant when that is what you want.
• The editor is enough for an arrow and a word on a picture meant for one person.

If what you capture is a meme for a group chat, Lightshot is fine. The rest of this page is about the screenshot that has anything in it you would not post on a billboard.

The privacy case, made plainly

A public link is a publication. With Lightshot the chain of events is: you press upload, the image is stored on a server you do not control, and a URL comes back that opens for anyone, forever, with no password. From there:

• Anyone with the link can open it. Forwarded once, it is out. There is no access list to revoke.
• The IDs are short. Researchers and journalists have walked prnt.sc’s ID space for years and published what they found. Your upload is one of them whether or not you ever share the link.
• Nothing in the tool checks the frame. Lightshot has no blur, no redaction, no warning. The customer’s email in the CC line, the API key in the terminal, the card number on the billing page go up with the rest.
• Deletion is a request to a third party. A file you want gone from your disk is a file you delete. An image on a vendor’s server has copies, caches and a retention policy you did not write.
• It is a compliance question. For anyone under customer-data, health, finance or residency rules, a screenshot of a production system on a public image host is an incident waiting for a date.

ScreenArt Pro removes the chain. Capture, editing, text recognition, redaction and recording run on your PC. There is no upload path in the app at all. Smart Redact finds email addresses, API keys, bearer tokens and JWTs, card numbers and IBANs, phone numbers, IP addresses and connection strings with a password in them, and covers each in the colour sampled from around it, so the cover reads as part of the page, before the file exists. When you do share, it is through your Drive, your Slack, your Notion or your own site, with the access rules and retention your organisation already has. The headache is not smaller; it is not there.

Where ScreenArt Pro goes further

The capture itself is better

Lightshot grabs a region and compresses it for the upload. ScreenArt Pro captures through Windows Graphics Capture at the physical pixels of each display, across monitors with different scaling, and writes an sRGB-tagged lossless PNG, so a 12px label is as crisp as it was drawn and the colours survive. Enhanced Render reconstructs captured UI text and flat geometry at the output resolution where it is confident, labelled as derived. The promise on the home page is “the highest-quality screenshots on Windows”.

A real editor

Lightshot’s pen, arrow and rectangle are painted into the picture. ScreenArt Pro’s editor is laid out like every editor you know, a tool rail on the left, the picture in the middle, an inspector on the right. Counters renumber when you reorder them; arrows, boxes, highlights and captions are layers you move, restyle or delete until you export; the original capture is always one comparison away; the project stays editable after export.

A finished picture in one click

Beautify puts the capture on a backdrop with room around it, rounds the corners, drops a soft shadow, lets a window light fall across the card and tilts it in 3D, with annotations and redactions staying on the card. A brand kit saves the look so every screenshot you publish matches the last one. The difference between a Lightshot grab and a picture someone put on a landing page is one button.

A screen recorder in the same app

Lightshot takes stills. ScreenArt Pro records the screen and opens the take in an editor where the polish is already on the timeline: a zoom that follows your clicks, a smoothed cursor, captions and keystroke badges, subtitles generated on your PC with SRT and VTT export, sixteen intro styles, twelve transitions, a 3D card with motion blur, all rendered on the GPU, exported as MP4, WebM with transparency or GIF in 16:9, 1:1, 4:5 or 9:16. The recording page has the details. Smart Redact works on the recording too, for every frame a secret is visible.

Your AI agent can take the screenshots

ScreenArt Pro runs as an MCP server, the open protocol Claude, Codex and most coding assistants use to call tools. Added in Claude Desktop, Claude Code, Codex or any MCP client, your agent can list your windows, read the labels on them, and save a cropped, annotated, branded screenshot of each step, singly or as a numbered set with a manifest, with Smart Redact applied by default. It can record a scripted walkthrough with the real pointer and replay a task you rehearsed once. You approve each session, anything that moves the mouse asks again, and Esc stops everything. Nothing is uploaded. The automation page lists all 25 tools.

Where Lightshot is still the right choice

• The picture is harmless and the link is the point. A meme, a game score, a screenshot for a public forum.
• You cannot install software and the browser extension is all you have.
• You want free, and you have read the section above and are fine with it.

Price, in full

Lightshot is free. The cost is the public link.

ScreenArt Pro has two plans, and the whole app is in both:

• €1.99 a month. Every update for as long as you subscribe. Cancel from your account.
• €24.99 once. Two years of updates, then keep the last version you installed for as long as you like.

€24.99 is less than a single year of Snagit ($39), less than CleanShot X’s first year on a Mac ($35), and a quarter of a year of Screen Studio ($108). Polar is the merchant of record, so there is a VAT-compliant invoice at checkout, and both plans have a 14-day refund. No account is needed to run the app.

Who should pick which

• Anyone who screenshots work systems, customer data or terminals: ScreenArt Pro. Nothing is uploaded, and the secrets are covered before the file exists.
• A developer publishing screenshots in docs, READMEs and release notes: ScreenArt Pro. Physical-pixel text, editable counters, a finished look in one click.
• A documentation or support team: ScreenArt Pro, for the MCP server.
• A founder or creator who also needs demo clips: ScreenArt Pro. The recorder is in the same project.
• Someone sharing a harmless picture with a group chat: Lightshot.

The bottom line

Lightshot is a fast free grab whose whole design is a public link, with no blur, no redaction and no way to take an upload back. ScreenArt Pro is the Windows screenshot tool that never uploads, covers secrets on its own, captures at the physical pixels, makes the picture finished in one click, records demo-grade video, and lets an AI agent take the screenshots for you. €1.99 a month or €24.99 once.

Install it, press the capture shortcut on the same window, and notice that the only place the file goes is where you put it.
