    About Threads Post

    Threads post images display best at 1080×1350 pixels (4:5 portrait). This format maximizes vertical space in the feed, similar to Instagram. Use high-quality, eye-catching visuals with clear subjects. Threads supports various aspect ratios but portrait orientation tends to perform best for engagement. Keep text overlays minimal and ensure they're readable at mobile screen sizes.

    Frequently Asked Questions

    Does resizing reduce image quality?
    Downscaling generally preserves quality. Enlarging a small image can cause blurriness. Start with the highest resolution source image available.
    Are images uploaded to a server?
    No. All processing happens entirely in your browser using the Canvas API. Your images never leave your device.
    What file format should I download?
    PNG preserves quality without compression artifacts. JPG produces smaller files suitable for photos. Choose based on your needs.
    Is this tool free to use?
    Yes, completely free with no signup, watermarks, or usage limits.
