Frequently Asked Questions

Is this image compressor free?›
Yes, 100% free with no file limits, no watermarks, and no account required.
How does the image compressor work?›
Images are compressed entirely in your browser using the HTML5 Canvas API. You choose a quality level (10–100%) and an output format (original, JPEG, PNG, or WebP). JPEG and WebP support lossy compression for significant size reduction; PNG is lossless so quality affects speed but not visual output.
Are my images uploaded to a server?›
No. All compression happens locally in your browser. Your images never leave your device and are not stored anywhere.
What file formats are supported?›
You can upload JPG, PNG, and WebP images. You can output to any of those formats as well. GIF and other formats are not currently supported.
How does this compare to paid tools like TinyPNG or Squoosh?›
Paid or freemium tools like TinyPNG upload your files to their servers and may apply more advanced compression algorithms. This tool is entirely client-side and free with no limits, making it ideal for everyday compression tasks where privacy matters.

What Is Image Compressor?

An image compressor reduces the file size of photos and graphics without visibly degrading quality — a process called lossy or lossless compression. Smaller image files load faster on websites, reduce storage costs, and meet file size limits on upload forms. Formly's free image compressor works entirely in your browser: no file upload to any server, supports JPG, PNG, and WebP, achieves up to 90% size reduction, and processes multiple images simultaneously. It is the fastest free alternative to TinyPNG and Squoosh for bulk image optimization.
