REDUCE PDF FILE SIZE
Drag & drop your PDF here
PDF files only (max 100 MB)
Reduce the size of your PDF files with our free online compressor. Choose from three quality levels to balance file size and visual quality. Files are processed securely on our server and never stored.
Screen (72 DPI) — Maximum compression. Ideal for on-screen viewing and email attachments.
Ebook (150 DPI) — Good balance between size and quality. Suitable for most use cases.
Printer (300 DPI) — Minimal compression. Best for documents that will be printed.
Results vary depending on the content. PDFs with images typically see 40-80% reduction. Text-only PDFs may see less improvement as they are already small.
Text remains sharp at all compression levels. Only images and embedded graphics are affected by the DPI setting.
If compression would make the file larger, we return the original file and let you know it was already optimized.
Yes. Your PDF is processed in memory and immediately discarded after compression. No one has access to your files.
