Auto Compress
Compress PDFs and images right in your browser — private, instant, free
Auto Compress is a free, browser-based tool that shrinks PDFs and images to meet any file-size limit — without uploading your documents to a server. All compression happens locally on your device, so sensitive files like bank statements, ID proofs, resumes, and visa or exam documents never leave your computer.
Set an exact target size (100 KB, 500 KB, 2 MB, and so on) or resize to specific dimensions, and download in seconds. It's built for the moment an upload portal rejects your file for being "too large" — government forms, court e-filing, visa applications, scholarship and exam portals, job applications, and email attachments.
No sign-up, no watermarks, no server uploads. Just fast, private file compression that works on any device. There's also a Chrome extension for one-click compression as you browse.
