PostMock is a tool that generates fictional mockups in the user's browser; we do not host a public library of user-created images. However, we take misuse and intellectual-property concerns seriously.
If you believe someone has used a screenshot created with our tool to deceive, impersonate, defame or harm you, please contact us with details. While we cannot control what users do with images after they leave our site, we want to know about abuse and will cooperate with lawful requests.
If you believe content on postmock.com itself infringes your copyright, send a notice including:
Send takedown and copyright notices to our contact form with "DMCA" or "Takedown" in the subject line. We aim to respond promptly to valid requests.
PostMock is a free browser-based generator for fake chat and phone screenshots. It renders a realistic mockup of a messaging app — WhatsApp, iMessage, Instagram DM, Snapchat, Discord, Telegram, Messenger, Tinder, Bumble, Hinge, ChatGPT, Claude — from text you type, and exports it as a high-resolution PNG. It is used for memes, parody, comedy content, social media posts, UI mockups, presentations and app-design previews.
Yes, and there is never a watermark on any export. Without an account you get 5 free PNG downloads, plus 3 more for each of up to 2 shares (11 in total). After that a free Google sign-in is required, and signed-in users have unlimited downloads. Video exports require sign-in from the first download. There is no paid tier and no subscription.
No install. PostMock runs entirely in the browser on desktop and mobile — there is no app to download and nothing to configure. Editing and preview happen client-side; the screenshot is rendered in your own browser rather than on a server. You can start typing and see the preview without an account.
Describe a scenario in plain language ("two friends arguing about pizza") and PostMock writes the whole conversation for you, in short, natural, realistic messages. It can also continue an existing conversation by writing the other person's next replies. Tweets can be generated the same way.
18 generators in total: 12 chat apps (iMessage, WhatsApp, Instagram DM, Snapchat, Messenger, Telegram, Discord, Tinder, Bumble, Hinge, ChatGPT and Claude), plus tweet/X posts, iPhone call and FaceTime screens, Instagram Stories, WhatsApp Status, and iPhone lock screens with notifications. It also has 80 ready-made scenario templates and 27 how-to guides. A separate tool downloads public Instagram reels and videos.
PostMock is built for parody, comedy, memes, content creation, mockups and design previews, and it says so on every page. Using a fabricated screenshot to deceive, defraud, impersonate a real person, harass someone, or manufacture evidence is wrong and in many places illegal — that is not what the tool is for and it is explicitly discouraged in the product. Creators should label parody content as parody.
PostMock publishes a DMCA and takedown page describing how to report content or misuse concerns.
