Frequently Asked Questions
Everything you need to know about trimming videos online
How do I reduce a PDF file size for email attachments?
- If your PDF is over the standard 25MB email limit, upload it to our free compressor. By choosing the "Screen (72 DPI)" preset, you can shrink a massive 50MB document down to 5MB, making it perfectly sized for fast email delivery.
Can I compress a PDF to a specific size like 100KB, 200KB, or 1MB?
- Yes! To hit strict portal upload limits, use our compression presets. The "Screen" setting offers maximum compression for the smallest file sizes (like 100KB or 500KB), while the "Ebook" setting offers a slightly larger file with better image quality.
Will compressing my PDF make the text blurry or unreadable?
- No. Our smart compression engine only resamples embedded images and background data. All of your text, vector graphics, and fonts remain 100% razor-sharp and perfectly legible at any compression level.
How do I compress a large scanned PDF document?
- Scanned PDFs are notoriously large because they act as giant images. They compress exceptionally well using our tool. Simply upload your scanned document and choose the Screen or Ebook preset for massive size reduction while maintaining complete document readability.
Will fillable forms and signatures still work after compression?
- Yes! Unlike basic compressors that flatten your document, our tool preserves all interactive elements. Your fillable form fields, checkboxes, digital signatures, and hyperlinks will remain completely intact and functional.
Do I need to download software to compress a PDF on Mac or Windows?
- No software installation like Adobe Acrobat is required. Our PDF size reducer works directly in your web browser. You can shrink documents instantly from your Windows PC, Mac, iPhone, or Android device.
Is it safe to compress confidential or financial PDF documents online?
- Absolutely. We treat your sensitive documents with bank-grade security. Files are processed securely over an encrypted connection and are automatically and permanently deleted from our servers within 5 hours. We never store, read, or share your documents.
