Steps
Each Facebook placement has its own ratio. Pick the right one and resize in three steps.
Details
Facebook cover photos are 851×315 px on desktop. But on mobile the top and bottom get trimmed. Keep text and logos in the center 560×315 safe zone so nothing gets cut off on a phone.
Use a crisp image at 851 px wide. Facebook compresses uploads regardless, but starting clean gives their encoder less to degrade. A JPEG at 851 px wide with moderate quality looks better than a 4000 px photo they crush.
Set dimensions, export, and move to the next step.
Square posts (1080×1080) look consistent in the feed and perform well on mobile. Landscape (1200×630) suits link shares and article previews. Portrait (1080×1350) fills more vertical space on phones.
If you share a link, Facebook pulls the og:image. Make that 1200×630 with the subject centered. The preview thumbnail is smaller so avoid fine text that becomes illegible.
Set dimensions, export, and move to the next step.
Ads Manager enforces aspect ratios per placement. Feed ads want 1080×1080 square or 1080×1350 portrait. Carousel ads use 1080×1080. Right-column ads are tiny at 254×133.
Text overlays in ads need to stay under 20% of the image area or Facebook may throttle delivery. Size your image to the placement, then add text sparingly in a separate design tool.
Set dimensions, export, and move to the next step.
Why it matters
No more trial and error uploading the wrong aspect ratio and watching it crop awkwardly.
The editor already has Facebook presets. These landing pages explain when to use each one.
PNG logos, JPEG photos, or WebP graphics — resize them all for Facebook in one session.
People search 'facebook post size' every day. This page connects them to a tool that solves it.
Practical answers about Facebook dimensions, ratios, and export settings.
851×315 pixels on desktop. On mobile the cover crops to roughly 640×360, so keep important content within the center 560×315 safe area. Use JPG under 100 KB for fast loading.
Square 1080×1080 px is the safest and most versatile. Landscape link shares work at 1200×630 px. Portrait posts can go up to 1080×1350 px. Facebook compresses everything, so start sharp at the right dimensions.
Feed ads: 1080×1080 (square) or 1080×1350 (portrait). Carousel: 1080×1080. Right column: 254×133. Collection ads: 1200×628. Text must stay under 20% of the image area. Files should be under 30 MB.
9:16 with a recommended resolution of 1080×1920 px. Facebook Stories occupy the full phone screen, so vertical content works best. Keep key elements away from the top 14% (profile info area) and bottom 5% (CTA area).
Yes, Facebook recompresses all images. Starting with the correct pixel dimensions and moderate quality (85-95 for JPEG) minimizes the double-compression damage. Oversized files get crushed harder.
1640×856 px. Like page covers, group covers crop on mobile. Keep the subject within the center portion. Use our presets or type these numbers in the editor.
1200×628 px (2:1 ratio). Event covers work similarly to link preview images. Text and the date overlay come from Facebook settings, not the image itself, so leave room for those.
Yes, but JPG is usually smaller for photos. Use PNG only when you need transparency or crisp text/logos. Facebook converts PNGs anyway, so a well-sized JPG often looks cleaner after their compression.
170×170 px on desktop, 128×128 on phones. Upload at least 180×180 px as a square. The editor can crop a photo to a square before you size it down. Profile pictures display as circles now.
Drop a whole folder into the editor, set one set of dimensions, and download all at once. The editor applies the same width and height to every image you loaded.
Yes. Open the page in your phone browser, upload images, and the editor handles it. Large batches may feel slower than on a desktop because processing runs on your device.
No. Downloads are clean. We show ads on the site, not on your images.
Facebook crops some placements (cover photos and link previews) to fit its layout. Uploading at the correct dimensions minimizes unexpected cropping. You can also crop intentionally in our editor.
Creator Studio handles scheduling and publishing. Our tool focuses purely on getting the image size right before you upload anywhere. Use both together.
Other tools on the site work the same way: open, edit, download.
Open the editor, pick a Facebook preset, set dimensions, and download files ready to upload.
