Image Compressor
Compress your images with the quality slider and download them as PNG, JPEG or WebP. Everything runs on your device.
What Does This Tool Do?
The Image Compressor shrinks the file size of your photos and images using a quality slider, while also letting you switch the output format to PNG, JPEG, or WebP. It's ideal for speeding up a website, staying under email attachment limits, or saving storage space.
How to Use It
- Drag your images into the box, or click to browse.
- Adjust the quality slider to your needs.
- Pick an output format (PNG / JPEG / WebP).
- Use "Download All" to grab every result at once.
Supported File Formats
PNG, JPEG, and WebP are all supported, and you can convert freely between them. If you need a different format (like PDF), use the File Converter instead.

Why Your Files Are Safe
This tool runs entirely client-side: your images are never uploaded to a server. Compression happens directly on your device via the browser's Canvas API.
Frequently Asked Questions
Is compressing images free?
Yes, it's completely free and requires no sign-up.
Which formats are supported?
You can upload PNG, JPEG, or WebP files, and export to any of those same three formats.
Why doesn't the quality slider affect PNG output?
PNG is lossless, so the quality setting doesn't change its size; try a JPEG or WebP output if you need a smaller file.
Can I compress multiple images at once?
Yes, select several files and process them in one batch, then download the results together.
Are my images uploaded to a server?
No. The entire compression process happens in your browser.
