Compress Image
Reduce JPG, PNG, and WebP file sizes while keeping visual quality intact.
Processed in your browser — files never uploaded
Compress Image shrinks the file size of your JPG, PNG, or WebP photos, making them faster to upload, email, and load on websites.
Compression happens entirely in your browser using the canvas API, so your photos never leave your device, and you can compress multiple images at once.
Frequently asked questions
Which image formats are supported?
JPG, PNG, and WebP images are supported as both input and output.
Can I compress multiple images at once?
Yes. Add as many images as you like and they'll each be compressed and bundled into a single .zip for download, or download individually.
How much can I shrink an image without losing quality?
The default quality setting typically reduces file size by 60-80% with no visible difference. You can adjust the quality slider for a different trade-off.
Are my photos uploaded to a server?
No. Compression runs locally in your browser using the canvas API, so your images are never sent anywhere.
