Image Minimizer

Ad renders come out as huge PNGs — often 10 MB each — and the uploader rejects them. Drop them here and get back upload-ready JPEGs at Meta's spec, usually 90% smaller with no visible difference in the feed.

What Facebook actually requires

Max file size30 MBMost uploaders choke well before this — keep files under a few MB.
Recommended1080 × 1080Meta downsamples to about this for feed delivery anyway.
Minimum600 × 600Below this Meta may refuse the image or render it soft.
Best ratios1:1   4:5   1.91:1Square for feed, 4:5 for mobile feed, 1.91:1 for link ads.
FormatsJPG or PNGJPEG is dramatically smaller for photographic and AI-rendered images.
Why images get so big PNG stores every pixel losslessly, which is great for flat graphics and terrible for photos or detailed AI renders — all that fine texture is what pushes a 2048×2048 render past 10 MB. JPEG at quality 90 is visually indistinguishable in a feed and routinely lands 70–95% smaller.
