Resize Image Online Free – Questions & Answers

How does client-side online image resizing work?
Modern web browsers support the HTML5 Canvas API and WebAssembly. We load your image into your device’s local memory, redraw it at your target dimensions, and export the file directly to your downloads without sending any data over the internet.
Can I resize in centimeters (cm) or inches instead of pixels?
Yes! Select "cm", "mm", or "inch" from the unit dropdown. Our engine uses your specified DPI (default 300) to calculate exact pixel dimensions.
Is there a file size limit?
We support photos up to 100 megapixels, which covers virtually all modern DSLR and smartphone RAW/JPEG outputs.
Is it really free with no watermarks?
Yes, 100% free with zero watermarks and no registration required.
