Frequently asked questions

What is the difference between Lossless and Strong compression?

Lossless rewrites the PDF structure and keeps text selectable. Strong converts every page to an optimized image, which gives the biggest savings — ideal for scanned documents — but text is no longer selectable.

Can I compress a PDF to under 200 KB for a government form?

Yes. Choose Strong, set the target to 200 KB and SolveIt lowers quality step by step until the file fits, when possible.

Is the compressed PDF safe to share?

Yes. It is a standard PDF created on your device.

About this tool

Large PDFs bounce off email limits and upload forms. Compress PDF shrinks your document by re-encoding page images at a quality you choose, or by optimizing its internal structure without touching quality.

Compress PDF runs entirely in your web browser. Your documents are processed on your own device and are never uploaded to our servers, which makes it safe for personal and business files.
