How it works
TeenyTools' image compressor runs entirely inside your browser using your device's own processing power. When you drop in a file, nothing gets uploaded to a server — the image is resized and re-encoded locally, then handed back to you as a download. That means faster results and your files never leave your computer or phone.
Why compress an image?
- Attach photos to emails that have strict size limits
- Speed up your website by using lighter images
- Save storage space on your phone or cloud drive
- Meet upload size limits on forms, job applications, or marketplaces
Frequently asked questions
Is this really free?
Yes. There's no limit on how many images you can compress, and no account is required.
Do you store my images?
No. Your image is processed locally in your browser and is never sent to our servers.
Will compressing reduce image quality?
Some quality is traded for a smaller file size, but the quality slider lets you find the right balance — higher values keep more detail, lower values create smaller files.
What file formats are supported?
You can upload JPG, PNG or WebP images. The compressed result downloads as a JPG file.
