Image Compressor
Shrink image file size for email, forms, and websites. Adjust quality, see the before/after size, and download — all on your device.
Private by design. Nothing is uploaded. Compression runs locally with Canvas in your browser.
How it works
- Select a JPG, PNG, or WebP image.
- Move the quality slider and optionally cap the longest side.
- Compare sizes and download the compressed file.
Frequently asked questions
Is this image compressor free?
Yes. Free to use with no account. Files are processed only in your browser.
How much can I compress an image?
It depends on the photo. Photos often shrink a lot at 70–85% JPEG quality. Graphics with text may need higher quality or PNG.
Does compression send my file to a server?
No. Everything stays on your device. We never receive the image.
PNG or JPEG — which should I download?
JPEG is usually smaller for photos. PNG keeps sharp edges and transparency better for logos and screenshots.
