How to Compress Photos for Facebook Marketplace
Facebook Marketplace re-compresses every photo you upload, which means a giant 12 MB file just uploads slowly and then gets squeezed anyway — sometimes ending up softer than you'd like. The smart move is to compress to a clean, light size yourself first. Facebook recommends around 1200 px on the longest side and a file size near 1 MB for fast, sharp results.
How to compress a Marketplace photo with QuickWand
- Open the free image compressor and drag in your photos.
- Use Resize → Max size to set the longest side to about
1200px — Facebook's recommended size, which also displays cleanly in the 1:1 feed. - Lower the Quality slider to around 82% and watch the live size estimate under each file settle near 1 MB.
- Keep the output format as JPG — Marketplace accepts JPEG and PNG only, not WebP.
- Download each photo, or click Download all (.zip) for your set of up to 10 photos.

Why pre-compressing beats letting Facebook do it
When you upload a massive file, Facebook's automatic compression has to do all the heavy lifting in one pass, which often produces visible artifacts. If you compress to ~1200 px at 82% first, Facebook has far less to strip out, so the final photo on a buyer's screen looks noticeably cleaner — and your upload finishes in a fraction of the time.
