How to Use the Reddit Post Preview Tool
Start by entering your subreddit name and username — both render in the post meta row exactly as Reddit displays them in the feed. Choose a post type from the dropdown: Text reveals a body text field, Image shows the upload area and renders your photo inside the card, Link shows a URL field and parses the domain into a clickable link bar, and Poll shows a four-option ballot preview. Type your post title in the text area — the progress bar and character counter track your usage up to the 300-character limit, warning you at 230 where long titles start to wrap awkwardly. Pick a flair by clicking one of the coloured preset chips or typing a custom label; the flair renders inline next to your subreddit name. Toggle NSFW, OC or Spoiler tags to see how they overlay the meta row. Click award chips to add Silver, Gold, Platinum, Helpful or Wholesome badges below the title. Enter custom upvote and comment counts and adjust the upvote ratio percentage. Switch between the light and dark Reddit themes with one click. When everything looks right, hit Screenshot to download a PNG — perfect for Reddit marketing strategy, subreddit mod submissions, or content calendar mockups.
Everything in This Reddit Post Preview Tool
Built for Reddit marketers, community managers, subreddit moderators, content strategists and social media agencies.
Pixel-accurate Reddit Feed Mockup
Every field update instantly reflects in an accurate Reddit post card — vote column, subreddit meta row, flair, title, awards, image or body text, and the full action bar — light and dark modes included.
Four Post Type Previews
Switch between Text (body preview), Image (photo card), Link (domain bar with URL) and Poll (four-option ballot card). Each type renders the correct Reddit layout in real time.
Flair & Award Display
Apply coloured preset flairs (Discussion, Question, News, Meme, Serious, Meta) or type a custom label. Toggle Silver, Gold, Platinum, Helpful and Wholesome award badges to see them render below the title.
Upvote Simulation & Ratio
Set custom upvote counts and an upvote ratio percentage — both render in the vote column. Click the upvote or downvote arrows to toggle the orange/blue highlight states, exactly as Reddit renders them.
Light & Dark Mode Preview
Toggle between Reddit's classic white light theme and its dark mode with one click. Both modes use authentic Reddit colour variables so the mockup matches exactly what Redditors see on either setting.
NSFW, OC, Spoiler & Pinned Tags
Toggle NSFW, Original Content and Spoiler labels to see how they appear inline in the post meta row. Enable the Pinned toggle to see the green moderator stickied banner above the post card.
Tips for Writing High-Performing Reddit Posts
1
Your Title Is Everything — Optimise It First
Reddit's feed shows only the title for most post types. It must be compelling, clear and complete on its own. Use the 300-character title field and preview here to verify the full title is legible and grabs attention before submitting.
2
Match the Tone of the Subreddit Precisely
Each subreddit has unwritten rules about voice, format and topic scope. Preview your post with the correct r/subreddit name to visualize how the title and flair combination reads in the context of that community before posting.
3
Use Flair to Signal Post Type Immediately
Subreddits with active flair systems see higher engagement on appropriately labelled posts. Toggle the coloured flair chips in this tool to verify how your chosen flair renders beside the subreddit name in the feed card.
4
Ask a Question to Drive Comment Volume
Question-format titles consistently generate more comments than statement titles on Reddit because they require a response. Preview the question mark placement and phrasing in the title field to confirm it reads naturally in the post card.
5
Keep Image Posts Visually Striking at Card Size
Reddit image thumbnails are cropped and compressed. Upload your image to the preview to see exactly how it fills the post card at feed dimensions — ensuring text overlays, faces and key visuals remain clear and unobstructed.
6
Preview in Dark Mode Before Posting
A significant portion of Reddit's user base browses in dark mode. Use the dark mode toggle in this tool to check that your title contrast, flair colours and image content all remain fully legible against the dark background.
Frequently Asked Questions
Is this Reddit post preview tool free? ▼
Yes — completely free with no account required, no watermarks and no usage limits. Open the page, compose your post and preview it live without signing up for anything.
Does this tool post to Reddit for me? ▼
No. This is a simulation and mockup tool only. It does not connect to the Reddit API. Once your post looks perfect here, copy the title and body text and submit it directly through Reddit.com or the Reddit mobile app.
What is the Reddit post title character limit? ▼
Reddit allows post titles up to 300 characters. The progress bar in this tool tracks your usage in real time and warns you at 230 characters — approximately where long titles begin to wrap or appear truncated in some feed layouts. Most high-performing posts keep titles between 60 and 150 characters.
What image sizes work best for Reddit posts? ▼
Reddit recommends images of at least 1200×628 px for link post thumbnails. For full image posts, 1080×1080 px (square) or 1920×1080 px (landscape) work well. Upload any image to this tool to preview how it fills the Reddit post card before publishing.
Can I preview NSFW, OC and Spoiler tags? ▼
Yes. Check the NSFW, OC or Spoiler checkboxes in the input panel to see the corresponding red, green or grey tags render inline in the post meta row — exactly as Reddit displays them in the feed and on the post page.
Is my post content or image stored anywhere? ▼
No. Everything runs entirely inside your browser using the JavaScript FileReader API and DOM rendering. No text, image or personal data is ever transmitted to any server — your content stays completely private on your own device.
