Frequently Asked Questions
I have a one-page PDF with light text—can it really be compressed to 20KB?
Yes, but only if the file is extremely simple—think: plain text, no images, no backgrounds, no embedded fonts. To reach 20KB, we strip away all non-essential elements. If your file is already minimal, our compression algorithm can reduce it effectively without damaging readability.What kind of content can be compressed to 20KB?
Only text-heavy, single-page PDFs can reliably reach 20KB. If your PDF includes images, custom fonts, vector elements, or high-resolution logos, it will be very difficult to compress it this small without serious loss in quality or content removal.Will the text still be clear after such extreme compression?
Yes. Even after significant compression, your text will remain readable. We retain all necessary font metadata, so while the layout may become simpler, the core content stays sharp and legible.I uploaded my file, but it only reduced to 40KB—why not 20KB?
The achievable compression depends on your PDF’s original structure. If your file contains embedded fonts, hidden metadata, vector shapes, or even small background colors, reaching 20KB may not be possible without affecting usability.How can I make my PDF easier to compress to 20KB?
Meeting the below requirements will make a PDF easily compressible to 20KB:- Use plain text only
- Avoid logos, icons, or background images
- Remove metadata and hidden layers
- Use a basic font like Arial or Times New Roman
- Avoid colored text or vector lines
Will my compressed file still be printable or email-friendly?
Yes, though keep in mind that ultra-compressed files may lose formatting and styling. For digital use like email attachments or document previews, it's perfect. For printing or formal submission, consider using a slightly larger size target (50–100 KB) for better quality.How do I know my file is secure?
All files are transferred over HTTPS and stored securely during processing. We automatically delete your file from our servers within one hour. We don’t store, view, or use your documents in any way.Can I compress password-protected PDFs to 20KB?
Not directly. You must first unlock the PDF using its password, then upload it for compression. We don’t accept encrypted or protected files for processing due to privacy concerns.Can I compress a PDF to 20KB from my phone or tablet?
Absolutely. Our tool is fully mobile-responsive. You can compress your PDF to 20KB from any device—Android, iPhone, iPad, or desktop—without installing any software.
