Frequently asked questions

How much smaller will my PDF get?

It depends on the content. Image-heavy PDFs (scans, photos) can shrink by 50-90%. Text-heavy PDFs with few images may see 10-30% reduction.

Will compression make my PDF look blurry?

The 'High Quality' preset preserves visual quality with minimal change. 'Balanced' offers good compression with acceptable quality. 'Maximum' prioritizes smallest size, which may reduce image sharpness.

Can I compress a PDF for email attachment?

Yes. Most email providers limit attachments to 20-25MB. Our compressor can typically reduce a large PDF to fit within email limits.
