PDF Compressor

Reduce a PDF's file size by re-encoding each page at a quality level you control. Best for scanned documents and image-heavy PDFs.

This compresses by re-rendering each page as an image at your chosen quality. It works best on scanned or image-heavy PDFs. Text in the output PDF will no longer be selectable — for text-based PDFs, file size savings are usually smaller.

A PDF that's too large to email or too slow to upload usually just needs its images re-encoded, not its content rewritten. This compressor shrinks file size while keeping your document readable, right on your device — useful for shrinking scanned documents, reducing PDF size for Gmail attachments, or getting under a file-upload limit.

How it works

  1. Add your PDFDrop in the file you want to shrink.
  2. Pick a quality levelLower quality means a smaller file. Start around 70% and adjust from there.
  3. Compress and downloadEach page is re-rendered and rebuilt into a new, smaller PDF.

Good to know

  • Best results on scanned pages, photos, and image-heavy PDFs
  • Output text is no longer selectable or searchable
  • Very large PDFs may take longer since every page is re-rendered

FAQ

Why isn't my text-based PDF getting much smaller?

Text-based PDFs are already compact. This tool's biggest savings come from image-heavy or scanned pages, since it re-encodes each page as a compressed image.

Will I lose text selection and searchability?

Yes — the output is image-based, so text can no longer be selected, searched, or copied. If you need to keep text editable, skip compression or keep the original alongside the compressed copy.

What quality setting should I use?

70% is a good starting point for most documents. Drop to 40–50% for maximum size reduction, or stay above 80% if the PDF contains detailed images.
