Higher quality produces a larger file. Lower quality reduces file size.
Select multiple social media sizes to generate all required variations from your uploaded photo at once:
ResizeKit's Social Media Image Resizer is a dedicated browser utility engineered to help creators, marketers, designers, and business owners optimize photos for every major social media channel. Social networks maintain strict display guidelines, aspect ratios, and compression algorithms. Publishing improperly sized images often leads to unexpected cropping, blurry downscaling, pixelation, or awkward black framing on mobile devices.
With our client-side resizing engine, you can instantly adapt any photo for Instagram, Facebook, YouTube, LinkedIn, X (Twitter), Pinterest, and TikTok. You have complete creative control between Fill & Crop for zero-border full-bleed graphics or Fit Entire Image to preserve complete design layouts, logos, screenshots, and text. Because all rendering occurs entirely in your browser using HTML5 Canvas, your files stay 100% private with no server uploads required.

Instagram prioritizes mobile-first visual engagement. While the classic 1080 × 1080 px square format remains popular, the 1080 × 1350 px (4:5 portrait) format occupies significantly more vertical screen space in user feeds, boosting visibility and click-through rates. Instagram Stories and Reels require 1080 × 1920 px (9:16 vertical ratio). Always keep critical text centered to prevent overlap with user interface controls.
Facebook feed posts display optimally at 1200 × 630 px. Desktop cover photos render at 820 × 312 px, but appear at 640 × 360 px on smartphones; keeping your essential graphic elements centered ensures they look great across both screen types. Facebook Stories use the standard vertical 1080 × 1920 px format.
A compelling 1280 × 720 px (16:9) thumbnail is the single most important factor for video click-through rate on YouTube. Channel header banners require a high-resolution 2560 × 1440 px canvas with a central "safe area" of 1546 × 423 px where logos and channel titles remain visible on all screen sizes including mobile, tablet, and TV displays.
For professional B2B marketing, LinkedIn post images with 1200 × 627 px dimensions ensure crisp rendering without awkward clipping on the feed. Company page header banners should be created at 1128 × 191 px, while personal profile headshots display clearly at 400 × 400 px.
X (formerly Twitter) displays single images in feed tweets best at 1200 × 675 px (16:9 widescreen ratio). Profile header banners require 1500 × 500 px (3:1 aspect ratio), and avatar pictures should be prepared at 400 × 400 px.
Pinterest is a visual search engine designed for vertical exploration. The standard recommended pin size is 1000 × 1500 px with a 2:3 aspect ratio. Pins that are too tall may be truncated in user search results, making the 2:3 ratio optimal for engagement.
TikTok relies entirely on full-screen 9:16 vertical media (1080 × 1920 px). When preparing still covers or video frames, remember to keep your focal subject away from the right-hand sidebar icons (like, comment, share) and bottom caption areas.
Choosing between Fill & Crop and Fit Entire Image depends directly on your creative content:
