Does Facebook compress images after upload regardless of size?

Yes, Facebook applies its own compression to all uploaded images — sizing correctly beforehand minimizes additional quality loss on top of that.

Is the ideal size different for a post versus a cover photo?

Yes, Facebook has separate recommended dimensions for posts, cover photos and profile pictures — this tool is tuned for standard feed posts.

Will my image get cropped if I don't resize it first?

Facebook auto-crops or letterboxes images that don't match its expected ratio, which is exactly what resizing beforehand avoids.

Does Facebook Post Resizer upload my files to a server?

No. Facebook Post Resizer runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Images uploaded to Facebook at the wrong size get compressed or cropped by Facebook's own processing, sometimes softening detail or cutting off part of the image in the feed. This tool resizes an image to Facebook's ideal post dimensions beforehand, helping it display at full clarity and with its intended framing once posted.
