Frequently Asked Questions

Answers to the most common questions about resizing images online.

Does resizing reduce image quality?

Resizing to a smaller size usually reduces detail. Upscaling can introduce softness. Our tool uses the Canvas API for high-quality bicubic-style interpolation, giving you the best result for both cases.

Will my image be uploaded to your servers?

Never. All resizing happens entirely in your browser using the Canvas API. Your image never leaves your device, so your privacy is fully protected.

What image formats are supported?

You can upload JPEG, PNG, WebP, GIF, and BMP images. You can also choose to save the resized image as JPEG, PNG, or WebP regardless of the original format.

What does locking the aspect ratio do?

When the aspect ratio is locked, changing one dimension (width or height) automatically updates the other to maintain the original proportions, preventing your image from appearing stretched or squished.
