How It Works

1

Upload Your Image

Drag & drop or click to select a JPEG, PNG, or WebP image. Files up to 20 MB are supported. All processing stays in your browser.

2

Adjust Quality

Use the quality slider to control compression level — lower values produce smaller files. Choose the output format that best suits your needs.

3

Compare Live Preview

Original and compressed versions appear side by side. File sizes and savings percentage update instantly as you adjust quality or change format.

4

Download

Click Download to save the compressed image. The Canvas API re-encodes your image at the selected quality level without uploading to any server.

About Image Compressor

Compress images directly in your browser using the HTML Canvas API. Reduce file sizes for faster web page loading, smaller email attachments, and storage savings. Adjust the quality slider to find the perfect balance between file size and visual quality. All image processing happens entirely on your device — nothing is uploaded to any server, ensuring complete privacy and security for your images.

Browser-Based Compression

Uses the Canvas API to re-encode images at reduced quality. No server calls, no uploads, no file size limits imposed by a backend — everything runs in your browser.

Live Side-by-Side Preview

Compare the original and compressed images in real time. Adjust the quality slider and see exactly how the compression affects visual quality before downloading.

Multiple Output Formats

Choose between JPEG, PNG, and WebP output. WebP offers superior compression for web use, JPEG is universally compatible, and PNG is best for images requiring transparency.

100% Private & Free

Images never leave your device. No account needed, no tracking, no storage of your files. The tool is completely free with no usage limits or watermarks.
