Frequently Asked Questions
How do I compress a PDF for email or online forms?
Upload your file, start with the Balanced profile, and download the smaller PDF. If the file is still too large for your portal, try Strong and compare readability.
What is the difference between Safe, Balanced, and Strong PDF compression?
Safe keeps the most original quality, Balanced is best for most documents, and Strong is for maximum size reduction. Scanned PDFs usually benefit more from Balanced or Strong than text-only PDFs.
Can I reduce a PDF to under 1MB?
Often yes, but exact file size depends on your source content. Large scans and high-resolution images may require stronger compression or source cleanup.
Will PDF compression change text quality or layout?
Layout and page order stay the same. Text PDFs generally remain sharp, while scanned/image-heavy pages can lose detail at stronger settings.
Why is my PDF still large after compression?
Some PDFs are already optimized, while others contain very large embedded images. If needed, compress image-heavy pages first, then re-export and compress again.
What is the maximum PDF upload size?
Up to 25MB per PDF on this online PDF compressor.
Is this PDF compressor free to use?
Yes. Tiny File Tools offers free browser-based PDF compression with no account required.
Are my files stored after compression?
No. Files are processed temporarily to generate your output, then deleted automatically. Tiny File Tools does not require signup for these tools.
Does this work on mobile and desktop browsers?
Yes. You can compress PDF files on modern desktop and mobile browsers without installing software.
