About this tool
This browser-based tool runs locally. Re-render a PDF at a selected compression level, compare the sizes, and download the result.
Common uses
- Reduce the size of scanned or image-heavy PDFs quickly.
- Compare compression levels without uploading the source document.
How to use it
- 1.Choose a PDF and select a compression level.
- 2.Review the compressed size and first-page preview, then download the result.
Limits and notes
- For meaningful savings, each page is re-rendered as JPEG; selectable text, vectors, forms, and annotations are not preserved.
- Processing stays in this browser; very large pages or complex files may be limited by device memory.
Frequently asked questions
Are my files uploaded?
No. The PDF is read and compressed in this browser and is not sent to a server.
Can I still copy text after compression?
Not guaranteed. Each page is re-rendered as an image, so this is best for scanned or image-heavy PDFs; keep the original when the text layer matters.
