Image Compressor
Files you add are processed entirely in your browser — nothing is uploaded to our servers.
How it's calculated
- • Runs entirely in your browser using the Canvas API — the image is never uploaded.
- • Re-encodes the image at your chosen quality and optional max width, then reports the new size and percentage saved.
