将PDF压缩至2MB

No. All PDF compression happens 100% locally in your web browser using client-side WebAssembly technologies. Your highly confidential documents (like Aadhaar, PAN, marksheets, passports, bank statements) never leave your device.

Simply drop your PDF file, enter your desired target size in KB or MB, and click 'Compress PDF'. Our intelligent compression engine automatically scales image assets and adjusts vector structures to compress the file down to your target size while maintaining visual legibility.

Because all processing occurs within your browser, we can only compress unlocked PDFs. If your PDF is encrypted or password-protected, please remove the password first before attempting compression.

Since the compression runs locally using your device's hardware memory, we comfortably support PDFs up to 50MB. Larger files may be slower depending on your machine's processing power.

Absolutely! CompressKaro is built as a fully responsive, lightweight web application that runs beautifully on iPhones, iPads, Android devices, as well as desktop computers.

Yes, fully. Unlike converters that flatten pages into image bitmaps, we optimize PDF structure tables and embed styles, keeping text copyable, selectable, and searchable.

You can use our specific Aadhaar or EPFO tools, or set the target input to 500KB (the EPFO portal size limit). The script will compress PDF images to meet the guidelines.

None. All features on CompressKaro are completely free, run without login limits, and add no watermarks, branding, or advertisements to your files.
