Too big to email or upload? This free compressor shrinks a PDF by re-rendering each page as a JPEG image at the quality you choose, then rebuilding the file. You always see the real before and after sizes — never a made-up saving.

It runs entirely in your browser, so your documents stay private. For a different kind of shrinking, first split out unneeded pages with the Split PDF tool, or convert pages to images with the PDF to JPG tool instead.

How to use

Drop a PDF into the box above, or click to browse.
Pick an image quality and a resolution — lower values mean smaller files.
Tap “Compress PDF” and wait while each page is re-encoded.
Read the honest before-and-after sizes, then download the result.

Why use Toolsvine

Many compressors promise a percentage and deliver something else, or upload your file to a server to do the work. Toolsvine compresses locally and reports the true sizes it measured, so if your file was already well optimised it says so plainly instead of inventing a saving.

How PDF compression works

Most of a PDF's size comes from the images on its pages — photos, scans and diagrams. This tool renders each page to a picture, then saves that picture as a JPEG at your chosen quality. JPEG compression discards fine detail the eye barely notices, and a quality of 60% is often far smaller than 90% while still looking clean on screen.

Why some PDFs barely shrink

A PDF that is mostly text, or one whose images were already compressed well, has little left to save. Re-encoding it may cut only a few percent — or, rarely, make it slightly larger. That is normal, and the result message tells you honestly when it happens. Lowering the quality slider or the resolution is the way to save more.

The trade-off to know

Compressed pages become images, so text inside them is no longer selectable or searchable, and very small print can blur at low quality. For forms and uploads that only need to be read, that is fine; for a document you still need to search or copy text from, keep the original too.

Frequently asked questions

How much smaller will my PDF get?

It depends on the file. Photo-heavy PDFs often shrink by 50–80%; text-only or already-optimised PDFs may save only a few percent. The tool reports the real sizes, so you always know.

Will compression make my PDF blurry?

At 60% quality and good resolution, most pages still look clean on screen. Very small print can soften, so check the result before sending it — and keep the original.

Can I still select text after compressing?

No. Pages become images during compression, so text is no longer selectable or searchable. Keep the original if you need that.

Is there a file size limit?

Files over 100 MB are refused so the browser tab stays responsive. Split a huge file first if you need to.

Are my files uploaded anywhere?

No. Compression runs entirely in your browser. Your document never leaves your device, and nothing is stored.
