Compress PDF

Many official portals require PDFs to be under 2MB. Choose our 'High' compression setting to aggressively re-encode embedded images, which can shrink document sizes by up to 80% while keeping text perfectly readable.

For extreme size reductions like 100KB, use the 'High' compression mode. If it's still too large, consider extracting only the necessary pages using our 'Split PDF' tool before compressing.

Compression mainly targets embedded images and photos. If your PDF is text-heavy or consists mostly of vector graphics, it is already stored efficiently and cannot be compressed much further without data loss.

No. Our compression engine only targets raster images (like JPGs and PNGs embedded in the file). Your text, fonts, and vector shapes remain completely untouched and perfectly sharp.

Low applies minimal image optimization for the highest quality. Medium is the sweet spot for everyday sharing. High heavily reduces image resolution (DPI) to achieve the smallest possible file size.

Scanned PDFs are essentially large images wrapped in a PDF file. Using the 'Medium' setting will significantly reduce the file size while maintaining enough clarity for reading and printing.

No. The entire compression process runs client-side. Your sensitive financial reports or personal IDs never leave your computer, ensuring maximum data privacy.

Instead of relying on Apple's Preview export settings which can ruin text quality, just drop your file into our browser tool. It smartly compresses images while preserving Mac-native fonts.

Currently, the tool optimizes one document at a time to ensure the highest quality processing and avoid crashing your browser's memory.

It scans the document for embedded high-resolution images, reduces their pixel dimensions, and applies efficient JPEG/WebP compression algorithms, stripping out unnecessary metadata.
