Compress a PDF; Smaller File, Still Readable

Compress one or more PDF files with selectable compression levels. Use the controls shown on the page, process the selected file or files, and download the result.

Select the compression level for each batch and rotate files when needed. Compression can change embedded-image quality, so no lossless claim is made. Upload multiple files and batch-process them for free, with no sign-up or ToolSpice watermark.

Frequently Asked Questions

What compression levels are available?
Three: Extreme (maximum size reduction), Recommended (good balance of quality and size), and Less Compression (highest quality with modest size savings). Recommended works best for most use cases.
Will compressing blur the text in my PDF?
Text and vector content usually remain sharp because compression mainly targets embedded images and redundant data. Image-heavy PDFs can show a visible change at stronger levels, and the final size reduction varies by document.
Can I compress multiple PDFs at once?
Yes. Upload several PDFs and they're all compressed with the same settings. Download the results individually or together.
Can I see how much smaller the file got?
Yes. After compression, the tool shows the original and compressed file sizes side by side so you can see exactly how much space you saved.
Can I rotate pages while compressing?
Yes. If any pages are in the wrong orientation, you can rotate them as part of the compression step - no need to use a separate tool.
