Large PDF files are a constant headache — email attachment limits, slow uploads to portals, and storage bloat. Our browser-based compressor reduces file size dramatically while preserving text sharpness and image quality, without uploading your documents to any server.
Compress your resume and portfolio PDFs to fit within online application upload limits without losing formatting.
Many government portals enforce strict 2-5MB upload limits. Compress tax documents, permits, and forms to comply.
Send large reports and presentations as email attachments by reducing them under the 25MB threshold.
Shrink scanned textbook chapters and research papers for easier sharing and storage.
No servers involved. Your files never leave your device.
Drag and drop or browse for your PDF file. It loads entirely into your browser's memory.
Use the slider to balance compression ratio vs. quality. 'Recommended' works for 90% of use cases.
Our WASM-compiled engine recompresses images, removes redundant data, and optimizes the PDF structure — all locally.
