About Image Resizer

Every platform wants different dimensions: 1080×1080 for an Instagram post, 1280×720 for a YouTube thumbnail, 600×400 for a blog hero. Image Resizer scales your pictures to exact pixel dimensions directly in your browser — with aspect-ratio locking so nothing stretches, and instant preview so you see exactly what you get.

Resizing happens locally via the Canvas API, so private photos never get uploaded. Batch mode handles whole sets of images to one consistent size, perfect for marketplace listings, email attachments and web performance optimisation.

Frequently Asked Questions

Will resizing reduce image quality?

Downscaling usually looks crisp because browsers use smooth interpolation. Upscaling beyond the original size can soften details — start from the largest image you have.

Can I keep the aspect ratio?

Yes — lock the aspect ratio and entering one dimension automatically computes the other so the image never distorts.

Are images uploaded to a server?

No. All resizing happens in your browser; the image never leaves your device.

Can I resize many images to the same size?

Yes — add multiple images and apply the same dimensions to all of them in one batch.
