Frequently Asked Questions
Everything you need to know about social media image sizing.
What is the best image size for TikTok in 2026?
TikTok uses 1080 × 1920 pixels (9:16 aspect ratio). This ensures your content fills the entire screen without black borders. Our "9:16 Reels / TikTok" preset gives you this exact size instantly.
What size should Instagram Reels and Stories be?
Instagram Reels and Stories both use 1080 × 1920 pixels (9:16). For regular feed posts, use 1080 × 1080 (square) or 1080 × 1350 (4:5 portrait) for maximum visibility. The 4:5 format takes up the most screen real estate in the feed.
What is the best LinkedIn profile photo size?
LinkedIn recommends 400 × 400 pixels for profile photos. For cover/banner images, use 1584 × 396 pixels. For shared post images, 1200 × 627 pixels works best. Our LinkedIn presets give you all three sizes instantly.
What's the ideal YouTube thumbnail size?
YouTube recommends 1280 × 720 pixels (16:9 aspect ratio) with a minimum width of 640 pixels. Higher resolution thumbnails (up to 2MB) look sharper on large screens and TV displays.
Are my images uploaded to your servers?
No. This tool runs 100% in your browser using the HTML5 Canvas API. Your images are processed locally on your device — nothing is sent to any server. You can verify by disconnecting from the internet and using the tool offline.
Does resizing or compressing reduce image quality?
Our tool uses high-quality canvas rendering with configurable output quality (50–100%). At 92%+ quality, the difference from the original is imperceptible. The smart compressor iteratively finds the best quality for your target file size without visible degradation.
What's the difference between Cover, Contain, and Stretch?
Cover fills the entire target area and crops overflow — best for social posts. Contain fits the image inside without cropping, adding background fill. Stretch distorts the image to fill exactly — rarely recommended but useful for specific cases.
Can I resize images for multiple platforms at once?
Currently you resize one preset at a time, but you can quickly switch between presets and download each version. Each click instantly re-renders the preview, so creating all sizes takes under a minute.
What file formats are supported?
You can upload JPEG, PNG, and WebP images. For export, choose between JPEG (small file size), PNG (lossless, supports transparency), or WebP (modern, best compression). WebP is ideal for web use.
What is the best Facebook post image size in 2026?
For Facebook shared posts, use 1200 × 630 pixels. For Stories, use 1080 × 1920 (9:16). Cover photos should be 820 × 312 pixels. Profile photos display at 170 × 170 but upload at higher resolution for clarity.
How do I make a circle profile photo?
Upload your image, then click the "⭕ Circle Crop" button below the preview. Drag and resize the circle selection to frame your subject, then click "Apply Crop." The result exports as a transparent PNG perfect for profile photos on any platform.
