Works on scanned documents, reports, and image-heavy PDFs.
Large PDF files are slow to email, upload, and share. PDF Compressor re-renders every page at an optimized resolution and image quality, dramatically cutting file size while keeping the document visually clear — ideal for scanned documents, reports full of images, or portfolios you need to send quickly.
Text stays legible at Low and Medium levels. High compression prioritizes smaller size and may soften fine text or image detail.
No — compression rasterizes each page into an image to achieve real size reduction, so the output is best for viewing, printing and sharing rather than text editing.
It depends on your device's available memory, since everything runs in your browser. Very large PDFs (100+ pages) may take longer to process.
No, all compression happens locally in your browser using JavaScript — your file is never uploaded anywhere.
