Frequently Asked Questions

How do I resize an image without losing quality?

Upload your image, choose a resize mode (pixels, percentage, or preset), and let the AI-powered quality preservation keep the output sharp.

What image formats does the image resizer support?

The resizer supports 50+ formats including JPG, PNG, WebP, AVIF, HEIC, TIFF, and BMP.

Can I resize multiple images at once?

Yes, use the bulk resize feature to process many images simultaneously in your browser.

Is my data safe when using the image resizer?

Yes, all processing happens locally in your browser. No images are uploaded to a server.

Will my image lose quality?

Only where the operation itself requires it. The change is applied once, at the settings you pick, so the file is not quietly re-encoded several times over.

Which image formats are supported?

JPEG, PNG, WebP and GIF are handled throughout. Less common formats are converted to a web-safe equivalent first.

Is my photo uploaded anywhere?

No. The work happens inside your browser on your own device, which is also why very large photos take a little longer.
