Compress scanned PDF

Rasterize selected pages and compress them as JPEG. Selectable text, vectors and interactions are lost; file size may not decrease.

How to use it

Choose scanned-PDF compression to re-encode page images at the selected quality for a more portable copy.

Sign in and choose files you are authorized to process.
Review tool options and file order, then explicitly start processing.
Download the copy after background processing finishes and inspect the result.

Before processing

Lossy compression may reduce text and image clarity. Check small text afterwards; smaller output is not guaranteed.

Keep your original file and inspect the generated copy before sharing or printing it.

Cost, limits and your files

OCR includes 5 free pages per account per Beijing calendar day. For each task, extra pages cost 1 credit per 5 pages, rounded up. Review the quote before starting; failed tasks release held credits and free-page allowance. Other document tools are free within their limits. Model-based translation has its own quote and requires explicit confirmation. No platform watermark is added unless you request one.

Processing requires a verified phone account. Files and downloads remain account-scoped; this public guide contains no user files. The toolbox accepts up to 20 inputs, with a combined limit of 100 MiB and up to 500 source pages. Individual tools have tighter output, pixel and time limits. Passwords are used only to process authorized encrypted files.
