Choose from three Reddit-specific presets: Post image (1200×628) for link previews that render correctly in the feed, Profile banner (1920×384) for the wide header strip on your user profile, or Avatar (256×256) for your circular profile picture shown next to every comment and post.
Export as PNG for sharpest results, then upload directly to your Reddit profile settings or attach to your post. No re-compression, no watermark.
From subreddit moderators setting up community branding to power users crafting link previews that stand out in the feed, Reddit contributors resize images to fit the platform's specific dimensions. Pixeltools makes it instant — no account, no upload limits, straight in the browser.
Moderators setting up or refreshing a community need a banner image at exactly 1920×384 and a community icon at 256×256. Resize both assets in seconds without opening a design tool.
When you share an external link on Reddit, the post image preview renders from the page's og:image or your attached image at 1200×628. Resize your graphic to that ratio so it fills the preview card cleanly instead of being cropped.
Reddit profile banners span the full width of your profile page at 1920×384 — wide and short enough that portrait or square images get brutally cropped on the sides. Resize to the correct ratio before uploading so nothing important is cut off.
Reddit avatars display as small circles next to every comment and username, and the platform crops them round from a square source. Resize and center your image to 256×256 before uploading so your face or logo sits correctly inside the circle.
Subreddits like r/Art and r/pics reward posts that look polished in the feed thumbnail. Resizing your original image to 1200×628 before posting ensures the preview card shows your work at its best rather than an awkwardly auto-cropped slice.
Brand subreddits and official community pages need consistent icons and banners that match company assets. Resize logos and header graphics to Reddit's exact 256×256 and 1920×384 specs so the community page looks intentional and professional.
For link preview and shared images, 1200×628 pixels works well across desktop and mobile. Reddit supports large images and lets users expand them, so high resolution is fine.
The Reddit profile banner is displayed at 1920×384 pixels (5:1). Keep key content centered, as the edges can be cropped on narrower screens.
Reddit avatars should be square, at least 256×256 pixels. They appear as a circle next to your username, so center your subject.
Reddit recompresses images, especially large JPGs. Upload at the recommended dimensions in PNG or high-quality JPG for the best result.
