Resize images for Reddit

Reddit’s very wide banners and circular icons, previewed live so nothing important lands in the crop.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Reddit Image Resizer

  1. Drop one image — a photo, logo or design export.
  2. Every size for this platform appears as a live preview with its dimensions and ratio.
  3. Slide between Fit and Fill on any card and drag the preview to reposition; nothing is stretched.
  4. Download a single size, or all of them as a ZIP.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Reddit banners are unusually wide: the new layout shows community banners 1072 px wide and 128–384 px tall, so a 1920×384 (5:1) file covers every layout; profile banners are 1200×400 (3:1). Community icons (300×300) and avatars (256×256) are displayed as circles and capped at 500 KB. Post images display largest at 4:5 (1080×1350); 16:9 (1920×1080) also works, with a 20 MB limit.

Every Reddit size on this page, verified for 2026: Post image 1080×1350 px (4:5 · under 20 MB), Landscape post 1920×1080 px (16:9), Link thumbnail 1200×628 px (1.91:1), Community banner 1920×384 px (5:1 · shown at 1072 px wide), Profile banner 1200×400 px (3:1), Community icon 300×300 px (1:1 · circle · under 500 KB), Profile avatar 256×256 px (1:1 · circle · under 500 KB). Each card is a live preview of your image in that frame — drag to reposition, slide between Fit (whole image, background added) and Fill (frame covered, edges cropped), then download the one you need or every size as a ZIP. Nothing is uploaded; the rendering runs in your browser.

For banners, use Fill and drag so the subject is in the middle — the left side sits under the community icon on many screens. For icons, keep the logo inside the central circle; the corners are cut off.

This is a pre-set view of the Social Media Image Resizer. Every other platform is one tab away.

Other presets

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
