Image Resizer & Compressor
Resize and compress JPG, PNG, or WebP images right in your browser — no upload to a server, completely private.
How the Image Resizer & Compressor works
Upload an image, adjust the width and height (or lock the aspect ratio), and set a JPEG quality level. Your browser redraws the image at the new size and lets you download it instantly.
Frequently asked questions
Is my image uploaded to a server?
No — resizing and compression happen entirely in your browser using the Canvas API. Your image never leaves your device.
What format is the output?
Resized images are downloaded as JPEG, with a quality slider so you can balance file size against image quality.
