Batch mode
Every image will be resized to and downloaded as one ZIP. Change the size below before you start.
Works with images up to roughly 50 MP (about 8000 × 6000 px) depending on your device's memory. WebP export is unavailable in a few older Safari versions — the option is disabled automatically when that is the case.

Download
Pick PNG, JPG or WebP. The file is compressed automatically to stay under Reddit's limit — or grab every Reddit size at once as a ZIP.
About the reddit banner size
A subreddit banner sits across the top of your community. The size most widely used is 1920 × 384 pixels, a 5:1 strip. Reddit's own published guidance is unusually hard to pin down: moderators can choose a small, medium or large banner height, and the figures circulating in design guides disagree with each other, ranging from 1920 × 384 to 4000 × 128. We use 1920 × 384 because it is the most commonly cited and it renders cleanly at every height setting.
Whatever number you start from, the design rule is the same and it is dictated by how Reddit crops. On narrow screens the banner is trimmed inward from both edges, so the outer thirds are decorative at best. Treat the centre of the strip as the only reliable canvas: community name, mascot, whatever identifies the place. Everything toward the edges should be texture or colour that can be cut without anyone noticing.

| Image | Size (px) | Max file | Source | What to know | Action |
|---|---|---|---|---|---|
| Community banner | 1920 × 384 | 500 KB | Recommended | 5:1. Reddit lets moderators pick a banner height, and published figures disagree — 1920 × 384 is the most widely used. | |
| Community icon | 256 × 256 | 500 KB | Recommended | Circular at every size, and tiny in feeds. One shape or letter works best. | |
| Post image | 1200 × 900 | 20 MB | Recommended | 4:3 keeps the whole image visible in the feed without a tap. |
Tips for Reddit
What actually makes the difference once the size is right.
The centre third is the safe zone
Reddit crops inward from the left and right on smaller viewports. A logo placed at the edge disappears on most phones.
Keep the file small
Reddit is strict about banner weight — aim for under 500 KB. This tool compresses to fit automatically.
Match the banner to the icon
The community icon sits on top of the banner. Matching colours makes a subreddit look maintained rather than default.
Test both banner heights
Moderators can switch the banner height in community settings. A design that only works at one height will break when someone changes it.
Frequently asked questions
What size is a Reddit banner?
1920 × 384 pixels, a 5:1 ratio, is the most widely used size. Reddit's own guidance varies with the banner height moderators select, and published figures disagree, so treat this as a strong convention rather than a fixed official spec.
Why do different guides give different Reddit banner sizes?
Because Reddit lets moderators choose a banner height, and the redesign changed how the image is scaled. Figures from 1920 × 384 to 4000 × 128 all circulate. Designing for the centre makes the difference largely irrelevant.
What file size does Reddit allow for a banner?
Keep it under about 500 KB. Larger files are commonly rejected or heavily recompressed.
Why is my Reddit banner cropped on mobile?
Reddit trims the banner inward from both edges on narrow screens. Keep anything essential in the middle third.
What size is a subreddit icon?
256 × 256 pixels, displayed as a circle. It is in the table on this page and included in the ZIP pack.
