What image size does Reddit support?

Reddit accepts images up to 20 MB. For best load times and quality, use at least 1080px on the longest side and keep file size under a few MB. Link posts often use 1200×628 for previews.

What format should I use for Reddit?

PNG and JPG are both supported. JPG is usually smaller for photos. PNG is better for graphics or when you need transparency.

Resize Image for Reddit – Sizes & Tips

Reddit supports a range of image sizes. This guide covers recommended dimensions for posts and link previews, and how to resize and compress your images for fast loading and good quality.

Recommended image sizes for Reddit

In-feed image post: 1080×1080 to 1920×1080 — flexible aspect

Banner / header: 1920×256 px or 1920×384 — subreddit style

Why size matters

Reddit allows images up to 20 MB, but very large files slow down loading. Resizing to a sensible resolution (e.g. 1080px or 1920px on the longest side) and compressing keeps quality good while improving speed. Our free resize image and compress image tools run in your browser so your photos never leave your device.
