FAQ
Common questions
What PDF size should I choose for upload?
Check the portal's required size first. If it says under 2MB, 5MB, or 10MB, use the closest target file size option.
Will compression keep the PDF readable?
FileFixer AI aims to keep pages readable, but very small target sizes may reduce image sharpness in scanned PDFs.
