About Image Compressor

Drag and drop an image — PNG, JPEG, WebP, AVIF, GIF, BMP, ICO, SVG, and even iPhone HEIC/HEIF photos or multi-page TIFF scans — pick a quality level, optionally shrink its dimensions to 75/50/25%, and compare the result side-by-side before downloading. Ideal for web publishing, email attachments and uploads with size limits.

Compression runs on an HTML canvas inside your browser, and HEIC/TIFF files are decoded locally with WebAssembly decoders: no uploads, no waiting, and no quality loss beyond what you choose. AVIF output is offered where the browser can encode it.
