Question 1

How do I resize an image without losing quality?

Accepted Answer

Use the highest quality setting and resize in small steps. For downscaling, our tool uses high-quality Lanczos-like resampling. Vector formats like SVG scale without any quality loss.

Question 2

What is the maximum file size I can resize?

Accepted Answer

There is no hard limit — everything runs in your browser using your device's memory. Most images under 50 MB resize without issues on modern computers and phones.

Question 3

Can I resize multiple images at once?

Accepted Answer

Yes. Select multiple files in the file picker (or drag several at once). Each image is resized with the same settings and downloaded individually.

Question 4

What image formats are supported?

Accepted Answer

Input: PNG, JPG, WebP, GIF, BMP and AVIF (if your browser supports it). Output: PNG, JPG or WebP — you can convert format while resizing.
