How to compress pdf
- STEP 1
Choose your PDF
Click the button, drag the file onto the page, or paste it from your clipboard. Nothing is transmitted anywhere.
- STEP 2
Pick how hard to squeeze
Leave metadata stripping on unless you need the original author and title fields preserved.
- STEP 3
Download the result
The compressed file saves straight to your Downloads folder. The original on your disk is never modified.
What survives, and what does not
Most PDFs are big for one reason: images saved at print resolution inside a document nobody will ever print. This tool repacks the document structure, drops orphaned objects and strips metadata, then writes a clean file. The text layer is never touched, so the result stays selectable, searchable and accessible.
Selectable, searchable text at full quality
Links, bookmarks and the table of contents
Page dimensions and print geometry
Form fields and their values
Document metadata, if you leave that option on
Some editing history from the authoring app
Honest limits are published on every tool page. If a tool cannot do something well, it says so here rather than letting you find out after the download.
Compress PDF questions
Will compressing a PDF make the text blurry?
No. Text in a PDF is stored as font instructions, not pixels, and this tool never rasterises it. Only images and the document structure are touched.
How much smaller will my file get?
It depends entirely on what is inside. A text-heavy report often drops 20–40% from structural repacking alone. A scanned document will barely move, because its weight is in the page images — image downsampling is the next thing being built.
Is there a file size limit?
No fixed limit and no daily cap. The practical ceiling is your own device memory, since the whole document is held in the browser tab while it is being rewritten.
Is my document uploaded to compress it?
No. Open your browser DevTools, switch to the Network panel and run a compression: the tool code downloads once, and then nothing else. There is no upload endpoint in this product.
