Try it now →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.
Yes. Exports are high-resolution PNGs with no watermark, intended for TikTok, Reels, YouTube Shorts, memes, skits and story-time videos. Creators are asked to present fabricated screenshots as parody rather than as real messages.
