Frequently asked questions

• Why is my PDF too large to email?+
  PDFs become large when they contain high-resolution images, many pages, or embedded fonts. Scanned documents are especially large because each page is stored as a full-resolution image.
• Will compressing affect text readability?+
  No. Text in PDFs is vector-based. Compression only re-encodes embedded images. Text, tables, and line graphics stay perfectly sharp at any compression level.
• How small can I compress a PDF?+
  PDFs with many images can reduce by 60 to 80 percent. Text-heavy PDFs compress less, around 20 to 30 percent. The tool shows before and after size so you know what you are getting.
• Is my PDF uploaded when compressing?+
  No. Compression runs entirely in your browser. Your file is never sent to any server.
• What is the email attachment size limit for Gmail?+
  Gmail allows attachments up to 25MB. However if the recipient uses a different provider their server may have a lower limit. Keeping PDFs under 10MB ensures delivery to any provider.
