Why use this tool?

Choose any percentage value to scale your image. Values below 100% shrink the image, 100% keeps it unchanged, and values above 100% enlarge it. The aspect ratio is always preserved, so your image will never appear stretched or distorted. Processing runs entirely in your browser — your files stay on your device and are never transmitted to any server. The downloaded filename includes the new pixel dimensions so you can instantly verify the output size without opening the file.

Frequently asked questions

Is the percentage scaling tool free?

Yes, it is completely free. No sign-up, no watermark, and no limit on the number of images you can scale.

Is my file private and secure?

Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.

Can I scale an image above 100%?

Yes. You can enter values like 150% or 200% to upscale an image. The aspect ratio is maintained automatically. Be aware that significant upscaling may reduce perceived sharpness since new pixel data is interpolated.

How is scaling different from resizing?

Scaling adjusts both dimensions by the same percentage, so the aspect ratio is always preserved. Resizing lets you set exact pixel values for width and height independently, which can change the proportions if you choose.

What formats does the scaler support?

You can upload PNG, JPG, WebP, and AVIF images. The export format and quality settings let you choose the best output for your needs.
