Compress a PDF
Shrink a PDF so it is easy to email.
Processed on your device — never uploaded
About this tool
Make large PDFs smaller so they're easy to email or upload elsewhere. Toolpit compresses your file locally and lets you download the lighter version immediately — no quality-destroying server round-trip, no watermark.
Your files never leave your device. Toolpit has no upload step and no server that can see your document — the work happens in this tab, on your machine, and stops the moment you close it.
How to compress a PDF
Drop in the PDF you want to make smaller.
Choose lossless tidying, or re-rendering pages for a much bigger saving.
Compress, compare the new size, and download.
Questions
Is my document uploaded?
No. There is no upload step and no server that could receive the file — the tool runs as code in this browser tab, works on the copy your browser opened, and forgets it when you close the tab. You can check this yourself: open your browser’s network panel and run the tool. You will see the page, its scripts and the ads that pay for the site — and no request carrying your file, because there is no endpoint to carry it to.
Why are there two compression modes?
"Compress PDF" means two different things. Lossless rewriting drops orphaned objects and packs the file more tightly — nothing degrades, and the saving is usually modest. Re-rendering turns each page into an image, which shrinks scan-heavy files dramatically but makes the text unselectable. Toolpit offers both rather than picking one and calling it magic.
My PDF barely got smaller. Why?
A PDF that is mostly text is already small and highly compressed; there is little left to remove. Large PDFs are almost always large because of images, so if lossless mode gains you nothing, the size is in the pictures — try the re-render mode and lower the quality.
Is there a file-size limit?
Never. There is no watermark, no page limit, no daily cap and no paid tier that unlocks the real output. Toolpit costs nothing to run per file, because your device does the work.
