How to Reduce Image Size Without Uploading
You can make images smaller without uploading them to a remote processing service.
Browser-local tools can decode an image, draw it to a canvas, and export a smaller copy.
Recommended tool
Open Compress ImageStart with compression
Compression is the fastest first step for photos and many website assets.
Lower quality gradually until the size and visual result are acceptable.
Resize if the dimensions are too large
A large pixel dimension is often the main reason a file is heavy.
Resize to the actual width and height you need.
Convert when the format is inefficient
WebP can be smaller than JPG or PNG for many web uses.
Use PNG only when the output specifically needs transparency or crisp lossless graphics.
