Best Image Format and Size for Pinterest Pins
Pinterest is a visual search engine — the quality, format, and dimensions of your pins directly affect how much traffic they drive. Pinterest displays images vertically, rewards tall pins (2:3 ratio), and heavily recompresses uploaded images. Getting the format right means your pins look sharp in feeds and search results.

Step-by-Step Guide
5 steps · takes under 1 minute
Use 1000×1500px (2:3 ratio) for standard pins
Pinterest recommends a 2:3 aspect ratio for standard pins. 1000×1500px is the optimal resolution — large enough for retina, small enough for fast loading. JPG at 85% at this size is typically 150–300KB.
Use 1000×2100px for infographic pins
Infographic and how-to pins perform well at taller ratios. 1000×2100px (approximately 1:2.1) shows more content in the feed. Pinterest allows ratios up to 1:2.1 — anything taller gets cut off with a 'see more' button.
Use JPG for photos, PNG for text-heavy graphics
JPG for lifestyle photos, product photos, food photography — smaller file size, looks identical to PNG at 85%+. PNG for infographics, quote pins, and graphics with text — PNG preserves sharp text edges without JPG's ringing artefacts.
Compress before uploading
Pinterest recompresses uploaded images. Upload at JPG 85% quality or PNG — giving Pinterest a good source reduces visible quality loss from its recompression.
Add descriptive alt text and keywords in the pin description
Pinterest uses pin descriptions as text signals for its search algorithm. Include the target keyword naturally in the first 50 characters of the description — this appears in search previews.
100% Private — Zero Uploads

Pro tip
Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
