Compress PDF

Rewrite a document to use less space. The result depends entirely on what is inside it.

Run this tool

The file is processed on this server and deleted as soon as the response is sent. Nothing is stored, and the result is returned directly to you rather than parked behind a link.

The document
Up to 25 MB. The file's contents are checked, not just its name.
Desired file size
Leave empty for standard lossless compression. To shrink the PDF to fit under a specific limit (e.g. email attachments, portal uploads), enter your target size in MB or pick a preset below.
Quick presets:
Standard compression packs streams and objects without loss. When a target size is set, MakeOverPDF intelligently optimizes high-resolution images and page streams to meet your requested size while preserving all pages and document structure.

Frequently asked questions

How does Compress PDF work on MakeOverPDF?
Rewrite a document to use less space. The result depends entirely on what is inside it. MakeOverPDF runs qpdf stream and object recompression on the server and returns: One PDF, downloaded immediately.
Is Compress PDF free and private to use?
Yes. MakeOverPDF requires no user account, watermarks nothing unless you use the watermark tool, and deletes your uploaded document from the private working directory as soon as the request finishes.
What are the file size and page limits for Compress PDF?
Streams are re-deflated at compression level 9 and objects are packed into object streams — the two things that shrink a file. Nothing is removed: no images are dropped, no content is discarded, no quality is sacrificed. No percentage is promised. What shrinks depends entirely on what is inside the document — a scan-heavy file gains a lot, a text file that is already packed may barely move. The produced file is what it is; the tool never edits numbers to look successful. The result is verified page for page against the input before it is offered for download, and the structure is checked the same way every other tool checks it.
How reliable is Compress PDF?
Reliable (qpdf stream and object recompression): No percentage is ever promised. A document that is already efficient may not shrink at all.
