Unlimited and free

No file size limits, no watermarks, no account. Compress as many images as you need.

Features that make a difference

Choose your format

Output as WebP, JPEG, PNG or AVIF. WebP and AVIF are the best choices for the web, JPEG for maximum compatibility, PNG for lossless output with automatic OxiPNG recompression.

Use case: web pages, emails, social media

Granular quality control

A 1-100 quality scale gives you full control over the balance between file size and visual fidelity.

Use case: finding the smallest file that still looks perfect

Batch compression

Drop in many images at once, tune the settings once, and recompress every file with a single click.

Use case: preparing a folder of photos for a website

Resize while compressing

Shrink the dimensions too. Scaling a 4000px photo down to 50% often cuts the file size by 90%.

Use case: sharing photos that are too large for messaging apps
