Frequently asked questions
Will resizing reduce image quality?
Downscaling (making images smaller) preserves visual quality very well. Upscaling beyond the original size can look soft, because no tool can add real detail that was not captured.
What sizes are common for social media?
Instagram posts: 1080×1080. Instagram stories: 1080×1920. YouTube thumbnail: 1280×720. Twitter/X header: 1500×500. Facebook cover: 820×312.
Can I resize multiple images to the same width at once?
Yes — drop a batch and set a width; every image is resized to that width with its own proportional height.
Are my photos private?
Completely. Resizing uses the canvas API in your own browser. Nothing is uploaded, logged or stored.
