Compress PDF
Clean the file structure and downsample large images while leaving text and vectors sharp.
Compress PDF online, free and without limits
Almost every upload form has a size limit, and almost every scanned document sails past it. Compression here works on the part of the file that is actually heavy: embedded raster images are downsampled and re-encoded, while text and vector graphics are left completely alone. That is the important difference from tools that flatten the whole page to a picture — your compressed contract stays sharp at any zoom, and stays searchable. The file structure is cleaned and unused objects are dropped at the same time.

What you get
- Text and vector art are never rasterized, so they stay crisp and selectable.
- Three strengths, so you decide the trade-off rather than the tool.
- Structural cleanup removes orphaned objects and unused data.
- If recompression would not actually help, the cleaned original is kept.
Questions about Compress PDF
What people usually want to know before they upload a document.
Why did my PDF barely get smaller?
Because it was already efficient. Files made of text and vector graphics — a typical invoice or an exported report — have very little to squeeze. Big savings come from scanned documents and photo-heavy files, where images dominate the size.
Will the text become blurry?
No. Text is never converted to an image by this tool, at any level. Only embedded photographs and scans are re-encoded.
How small can a PDF get?
It depends entirely on the source. A photo-heavy scan often drops by 60-80% on Strong; a text-only document may move only a few percent because there is nothing to remove.
