Compress PDF — Reduce File Size
Shrink a large PDF for email or upload limits, free and private.
Scanned documents and photo-heavy PDFs can quickly balloon past the size limits imposed by email providers or upload forms. This tool shrinks a PDF by re-rendering each page as a compressed image at a quality level you choose, then rebuilding it into a smaller file — all inside your browser.
Be aware of the trade-off: because this works by converting each page into a compressed image, any text in the original PDF will no longer be selectable, searchable, or copyable afterward. This makes the tool a great fit for scanned paperwork, photographed documents, or PDFs that are already essentially images — but not a good choice for text-heavy documents you need to keep searchable or accessible to screen readers.
Choose a compression level — High, Medium, or Small file — upload your PDF, and the tool renders and recompresses every page locally before saving the result. Nothing is uploaded to a server at any point; the same local rendering approach used by our PDF to JPG tool powers this one too.
Frequently asked questions
How does this tool actually compress a PDF?
Each page is re-rendered as a compressed JPEG image at the quality level you choose, then rebuilt into a new, smaller PDF.
Will my text still be selectable and searchable after compressing?
No. Because pages are converted to images, text is no longer selectable or searchable afterward. This tool is best for scanned documents or PDFs that are already made of photos, not for text documents you need to keep searchable.
How much smaller will my file get?
It depends heavily on the original content and the quality level chosen — scanned, image-heavy PDFs typically shrink the most.
Is my PDF uploaded to compress it?
No. Compression happens entirely in your browser using a local PDF renderer — your file is never uploaded.
