Why Compress your PDFs?
Large PDF files can be difficult to email or upload to websites with size limits (like government portals or job applications). Our compression tool reduces the resolution of images within the PDF, drastically shrinking the file size while keeping it readable.
FAQ: PDF Compression
How much can I reduce the file size?
It depends on the original file content. Files with many large images can often be reduced by up to 80% using the "Low Quality" setting.
Is my data safe?
Absolutely. The compression happens locally in your browser. We never see, read, or store your files.
Why isn't the text selectable after compression?
To achieve high compression ratios in the browser, we convert pages to optimized images. If you need selectable text, please use the "High Quality" setting or consider using our OCR tool later.
