Resize for Social Media
Every platform has different size requirements. Instagram supports 1080x1080 feed posts and 1080x1920 Stories, while YouTube currently recommends 3840x2160 custom thumbnails. Choose a preset, then decide whether to fit the full image or fill the frame.
Optimize for Web
Large images slow down your website. Visitors leave, search rankings drop. Resize product photos, blog images, and hero banners to web-friendly dimensions. Your pages load faster without sacrificing the quality your brand needs.
Fit Images in Emails
Email providers reject attachments over 10-25MB. Marketing platforms have their own limits. Resize photos before attaching so your messages actually reach the inbox, not the spam folder or bounce pile.
Prepare for Print
Print shops need specific pixel dimensions for flyers, posters, and banners. Too small and your image looks pixelated. Too large and you're wasting file space. Set the exact dimensions your printer requires and get crisp results every time.
Resize With Precision
Get the exact dimensions you need, every time.
Fit Modes
Choose how your image fills the frame. Fit, fill, crop, or pad. You control how the resize handles aspect ratio differences.
Platform Presets
Fit perfectly for Instagram, TikTok, YouTube, Facebook, LinkedIn, and more. One click gets you the exact dimensions each platform requires.

@beachxbunnyFast and Straightforward
Resizing photos for social media should be a cinch, but most editing programs are a pain to use. Of the dozen I’ve used, Instasize is the fastest, easiest and most consistent...
