What is the best image size for Facebook posts?

Facebook post images: 1200×630px (shared links). Profile photo: 170×170px display (upload at 360×360px minimum). Cover photo: 851×315px. For highest quality in albums, use 2048px on the longest edge.

Does Facebook compress photos when you upload them?

Yes. Facebook recompresses photos to JPEG. Uploading from the mobile app compresses more aggressively than from desktop. For best quality, upload from a desktop browser.

Why do Facebook photos look worse than the originals?

Facebook's JPEG compression is most visible on images with text, thin lines, and fine detail. Uploading at Facebook's own recommended resolution (2048px longest edge) minimizes additional compression.

Should I upload photos to Facebook as PNG or JPG?

JPG for photographs. PNG for graphics with text or sharp edges — but note Facebook converts PNGs to JPEG, so the advantage is limited. Start with JPG for photos to avoid double-conversion.

Can I compress images for Facebook on my phone?

Yes. Open FixTools in your mobile browser (Safari or Chrome), compress the image, and upload directly to the Facebook app from your photo gallery.

Compress Image for Facebook

Facebook automatically recompresses uploaded photos to JPEG, and the compression is particularly noticeable on images with fine detail or text. Facebook's recommended photo upload dimensions are 2048px on the longest edge. Pre-compressing at 85% quality at those dimensions gives you the best final quality in the Facebook feed.
