About Compressify
Compressify is a free online tool that lets you compress PDF files and images right inside your web browser. There is nothing to install and no account to create. Most importantly, your files never leave your device — all compression happens locally in your browser, so your documents and photos stay private.

Compress PDF
Reduce the file size of large PDFs — ideal for scanned documents, image-heavy reports, and files that are too big to email or upload. Choose a compression level to balance size against quality.
Compress Images
Shrink JPG, PNG, WebP, GIF, and BMP images. Adjust the quality and maximum dimensions to get a smaller file while keeping the picture looking great.
How it works
- Open Compressify and choose the PDF or Image tab.
- Select a file from your device.
- Pick a compression level (and quality/size for images).
- Download your smaller file — done in seconds.

Frequently asked questions
Are my files uploaded to a server?
No. Compression happens entirely in your browser. Your files are never transmitted to us or anyone else.
Does it cost anything?
No. Compressify is completely free to use.
What file types are supported?
PDF documents, and JPG, PNG, WebP, GIF and BMP images.
Will compressing reduce quality?
Compression is lossy, so there is a trade-off between file size and quality. You control the level, so you can choose the balance that suits you.
