Our PDF compression engine parses the PDF object tree directly inside your browser. It removes duplicate fonts, flattens redundant metadata streams, downsamples oversized embedded images with bilinear interpolation, and applies Flate stream compression without altering document typography.
Q.Can I set a specific target size in KB (e.g. under 200 KB)?
Yes. You can use our precision Target Size slider or preset buttons to compress your document to exact thresholds like 200 KB, 100 KB, or 50 KB—ideal for government job applications, university submissions, and portal uploads.
Q.Are my confidential documents uploaded to a remote server?
No. All compression algorithms execute locally within your device browser using WebAssembly. Your confidential PDF files never leave your computer or phone.
