Frequently Asked Questions

Everything you need to know about browser-based image processing.

Will resizing distort my image aspect ratio?

By default, aspect ratio lock is maintained so your image automatically scales proportionally when you adjust width or height.

What social media presets are included in the resizer?

We provide presets for Instagram Posts (1080x1080), Instagram Stories (1080x1920), YouTube Thumbnails (1280x720), Twitter Headers (1200x675), and HD / Full HD / 4K resolutions.

Why should I resize images before uploading to my website?

Serving full 4000px camera photos on web pages wastes bandwidth and slows down page loading. Resizing images to match display dimensions saves data and speeds up rendering.

Can I batch resize multiple photos simultaneously?

Yes! Upload a queue of photos, set your target width/height or preset, and all images will be resized and ready for batch ZIP download.

Is there any loss of image sharpness when downscaling?

No, our engine utilizes high-quality 2D canvas bilinear resampling algorithms to ensure crisp text and sharp details after scaling.
