What does Image Resizer do?
Resize photos and graphics to custom pixel dimensions with high quality. High-resolution cameras, smartphones, and graphic software generate images in a wide range of formats—from modern space-saving WEBP and AVIF files to standard JPGs, transparent PNGs, and scalable SVGs. However, many job application portals, government upload forms, and email clients still enforce strict image format and file size limits.
This tool helps you adjust, crop, or compress your images so they meet your exact requirements without sacrificing image sharpness.
How in-browser image processing works
Rather than sending your personal photos across the internet to an unknown server, our image tools utilize the HTML5 Canvas API and modern WebAssembly codecs directly in your browser. When you drop an image onto the page, your browser decodes the pixel grid into memory, performs the requested resizing or compression, and produces the output file instantly.
This ensures you never have to wait in an upload queue, and your private photos remain strictly on your own computer or phone.

Frequently Asked Questions
Q: Does compressing a photo reduce its physical resolution?
A: Not unless you choose to resize it. Visual compression works by trimming imperceptible color data while keeping pixel dimensions unchanged.
Q: Does this format support transparent backgrounds?
A: JPG does not support transparency. If you need a transparent background, convert to PNG instead.
Q: Are my personal photos private and secure?
A: Yes. Most of our tools run directly inside your browser so your documents stay on your device. We never store, copy, or transmit your images.
Q: Can I convert multiple images at once?
A: Yes, batch processing is supported for our core image tools so you can process photos in bulk.
