Frequently Asked Questions
What platforms does this tool support?
We support all major social media platforms: Instagram (Feed, Story, Reels), TikTok, YouTube (Thumbnails, Shorts), Twitter/X, LinkedIn, Facebook (Posts, Stories), Pinterest, and Snapchat.
Is this social media resizer free?
Yes, completely free with no limits or watermarks. All processing happens in your browser, so there are no server costs for us.
Are my files private?
Absolutely. All processing happens locally in your browser. Your images and videos never leave your device or get uploaded to any server.
What file formats are supported?
For images: JPG, PNG, and WebP up to 50MB. For videos: MP4, WebM, and MOV up to 500MB. Images output as JPG, videos output as MP4.
Can I resize videos too?
Yes! Video resizing uses FFmpeg.wasm which runs entirely in your browser. The first video may take longer as it loads the video processor (~31MB, cached after first use).
How do I download all files at once?
After processing, click the "Download All as ZIP" button to get a single ZIP file containing all your resized images or videos, named by platform.
Why are some platforms cropped differently?
Each platform has different aspect ratios. Instagram Feed is 1:1 (square), Stories are 9:16 (vertical), YouTube thumbnails are 16:9 (horizontal). We use center-crop to fit your content.
