How to edit a screenshot with Supademo
Upload or capture
Take a screenshot with the Chrome extension or upload any image from your device. Works from any OS. No app required.
Edit and annotate
Add text, arrows, blur, or redact areas. Use AI to edit text directly inside the image. No Photoshop skills needed.
Download or share
Export as PNG or generate a shareable link. Update the screenshot later and the link reflects it. No re-sending.
What makes Supademo's screenshot editor different
AI edits text directly inside the image
Most editors let you paste a text box on top. Supademo uses AI to modify existing text inside the screenshot, so you can edit screenshot text online, change screenshot text instantly, or fix typos in tutorial captures. Works as a browser-based screenshot editor app — no installs.
How AI screenshot text editing works →
Blur and redact in one click
Select any area and apply blur or hard redaction instantly: passwords, API keys, pricing, internal UI. The result looks clean and intentional, not like something slapped over the content.

Share as a live link, not a file
Generate a shareable link instead of attaching a PNG. Edit the screenshot later and the link updates automatically. No stale files, no re-sending, no version confusion.
How live screenshot sharing works →Why we built Supademo's free screenshot editor
“Before we shipped this, I was personally Photoshopping screenshots for our marketing site. Each fix took about 20 minutes. Matching the UI font is the slow part. Supademo's free screenshot editor exists partly to stop me doing that. Now I edit screenshot text in under 30 seconds, and our PMs picked it up for mockups once they saw how fast it was.”
“With Supademo's free screenshot editor, what I cared about was the output being something you'd want to share. The screenshot you drop in should come out polished and on-brand. You can grab it as a tracked link or paste it into Slack. Every screenshot should look as clean as the first, even when someone runs ten through before a deck review.”

What can you do with a free online screenshot editor?
Upload your screenshot to Supademo's free editor, use the tools to annotate, blur, or modify the image, then download or copy a shareable link. No account or download required.
How can I edit text inside a screenshot?
Use the AI text editing feature: upload your screenshot, select the text area, and Supademo's AI modifies or replaces the text directly inside the image, without any manual masking or Photoshop work.
Can I blur or redact part of a screenshot?
Yes. Select any region and apply blur or redaction in one click. Useful for hiding passwords, personal information, API keys, or anything you don't want visible before sharing. Works similarly to Supademo's standalone image blur tool.

No. The screenshot editor is free with no account required. Sign up if you want to save, organize, and manage your screenshots over time.
Is my data secure?
Yes. Supademo is SOC 2 Type II compliant. Screenshots are not stored on our servers unless you explicitly generate a shareable link. You control who sees what.
Does Supademo's screenshot editor work on mobile?
Yes. Upload screenshots from your iPhone or Android directly in the browser — no app download needed. The editor works on any device, similar to other browser-based capture tools.
