PDF Compressor

Reduce PDF file size for email attachments, document uploads and everyday sharing. PDF Compressor helps you compress PDF documents on your phone, compare the original with the result, and save or share the compressed file. No signup, no ads, and no added watermarks. Your original file stays unchanged. 1. Choose how to compress your PDF Start with Recommended compression or select Strong compression to prioritize size reduction. Use custom settings to adjust image resolution (DPI) and JPEG quality. Try different settings from the same original and review the result before saving. 2. Set a target file size Choose a size suggested from your original file, or enter your own target in KB or MB. The results show the actual file size and whether the target was reached. Compression depends on document content, so a specific target size cannot be guaranteed. 3. Compare before and after compression Switch between the original and compressed versions on the same page. Zoom in and move between pages to review text and images. Check the output size and reduction percentage, then decide whether to save or try different settings. 4. Compress PDF files offline Compression and result checks run on your device, without uploading your document to a compression server. Files already on your phone can be processed without an internet connection. Loading files from a cloud storage provider may require internet access. 5. Save, open and share Save your compressed PDF to the Downloads folder. Open the saved file or share it through email, messaging or other installed apps. Recent saved files are available in your history, so you can open and share previous results again. 6. Keep the original and stay in control PDF Compressor creates a separate result instead of overwriting your selected file. Cancel compression when needed, change your settings and try again. Each new attempt starts from the original PDF. How to use Select a PDF, choose your compression settings and start. Compare the result, then save or share it when you are ready. Please note: - One PDF file is processed at a time. - File size reduction and image quality changes vary by document and settings. - Some PDFs may not become smaller. - Password-protected and digitally signed PDFs are not supported for compression.
