How It Works
Upload your image
Drag and drop or click to select any JPEG, PNG, or WebP file up to 50 MB. Begin with the sharpest, highest-resolution copy you have for the cleanest result.
Pick a Facebook format
Choose a feed Post Image, a vertical Story, or a Cover Photo. Each option lists the precise pixel size and aspect ratio Facebook renders that placement at.
Resize and download
Hit download and your image is center-cropped to the target size, then saved with a clear filename noting the placement and dimensions.
Facebook Image Presets
| Platform | Format | Dimensions | Aspect Ratio |
|---|---|---|---|
| Post Image | 1200 × 628 px | 1.91:1 | |
| Story | 1080 × 1920 px | 9:16 | |
| Cover Photo | 820 × 312 px | ~2.6:1 |
Popular Use Cases
Local Businesses
Keep your Page polished with a cover photo that fits and feed images that never get awkwardly cropped on desktop or mobile.
Paid Advertisers
Get creative into the 1200 × 628 link-post size that Facebook ads favor, so your image displays in full without truncation in the feed.
Community & Group Admins
Produce on-brand Stories and post graphics in seconds, keeping a consistent look across every update you share with members.
Campaign Planning
Prepare every Facebook asset before launch day so you can drop them straight into your scheduler without last-minute resizing.
Pro Tips
Start from your highest-res original
Scaling a large source down always beats scaling a small one up. Use the original file, not an image you already exported or compressed once.
Center the subject before uploading
This tool center-crops outward from the middle of your image. Place your key subject in the center of the original so it survives the crop on every Facebook placement.
Use 1200 × 628 for link posts
When you share a link with a custom image, Facebook expects 1200 × 628. Hitting that size keeps your thumbnail crisp and full-width instead of cropped.
Mind the cover photo crop on mobile
Facebook displays cover photos differently on desktop and phones. Keep important details away from the far edges so nothing essential gets clipped on smaller screens.
PNG for graphics, JPEG for photos
The tool keeps your input format. Upload PNG for logos and text overlays to avoid artifacts; use JPEG for photography to keep file sizes lean.
Compress before publishing
Heavier images upload slowly and Facebook re-compresses them. Run resized files through the Image Compressor first to control quality yourself.
Next step
Sized for Facebook? Keep it moving
Resizing is one step. Line up your posts with the Facebook scheduler, trim file size with the image compressor, and see how a cross-platform strategy keeps every channel consistent.
