Frequently asked questions
Will a text PDF reach 800 KB more easily than a scan?
Yes, usually. A text-based PDF has much less image data than a scan, so it often reaches 800 KB at Low or Medium. Scans store each page as a picture, which can raise the PDF file size. Our PDF compressor can optimize those images while keeping the words readable.
Will the text stay easy to read?
Our online tool keeps text clear when the source contains real text layers. Scanned pages depend more on image quality, resolution, and contrast. To compress PDF online without losing useful detail, review small print, charts, and faint marks after you download the result.
If the pictures are already small, what else keeps the file above 800 KB?
Embedded fonts and page thumbnails can increase PDF size. Form data and annotations add size too, as can hidden document details. Our tool removes data such as duplicate fonts, metadata, and embedded objects, so check the estimate at Medium or High. If it is still over, remove pages you don't need.
Is 800 KB a large file?
An 800 KB document is small for most email, upload, and storage tasks, though each service sets its own rules. If a form needs a compact copy, our service lets you compress PDF to 800 KB online free of charge, with no installation.
