What Is This Tool?

This free image compressor lets you reduce the file size of JPG, PNG, and WEBP images directly inside your browser — no account, no server, no waiting. Unlike cloud-based services that upload your files to a remote server, this tool uses your device’s own processing power via the JavaScript Canvas API. Your images never leave your computer at any point during the process, making it the safest way to compress sensitive or personal photos.

Whether you’re a web developer optimizing page load speed, a designer preparing assets for a client, or simply trying to shrink a photo before sending it by email, this tool gets the job done in seconds — with full control over output quality.

How to Use — 3 Simple Steps

1
Upload your image Drag and drop an image onto the upload area, or click to open the file browser. Supports JPG, PNG, and WEBP. For batch compression, use the batch panel below the single-image tool.
2
Adjust compression settings Use the quality slider to control output size. The default setting of 85% delivers an excellent balance between file size reduction and visual quality. Optionally set a max width to resize the image at the same time.
3
Download your result Click the Download button to save the compressed image directly to your device. For batch jobs, all compressed images are packaged and downloaded together as a single ZIP file.

Frequently Asked Questions

No. All compression is handled entirely inside your browser using the JavaScript Canvas API. Your image data is never transmitted over the internet. Once you close the tab, no trace of your file remains anywhere.
The compressor supports JPG (JPEG), PNG, and WEBP. Output is delivered in the same format as the original input, unless you enable the “Force JPEG” option, which converts all formats to JPEG for maximum file size reduction.
Only if you set a “Max Width” value in the settings panel. By default, the tool preserves the original width and height — it reduces file size through quality adjustment only, without changing the pixel dimensions.
There is no fixed limit. Batch size is constrained only by your browser’s available RAM. Modern browsers typically support processing hundreds of images in a single session without any issues.
Yes. There are no subscriptions, no hidden fees, and no “Pro” upgrade tier. Every feature — including batch compression and quality control — is available to every visitor, free of charge, permanently.
Once the page has fully loaded in your browser, the core compression function works without an active internet connection. Some features that rely on external libraries may require connectivity, but basic single-image compression is fully offline-capable.
