The Acrobat online PDF compressor balances an optimised file size against the expected quality of images, fonts and other file content. Just drag and drop a PDF into the PDF compression tool above and let Acrobat reduce the size of your PDF files without compromising quality.
For more refined control of optimisation settings, you can try Adobe Acrobat Pro for free for seven days. Acrobat Pro lets you customise PPI settings for colour, grayscale and monochrome image quality. You can also use PDF editor tools, edit scans with OCR functionality, convert PDFs to Microsoft PowerPoint and other file formats, convert PNGs and other image file formats, organise and rotate PDF pages, split PDFs, optimise PDFs and more. You can use Acrobat on any device, including iPhones and on any operating system, including Mac, Windows, Linux, iOS or Android.
With the Acrobat PDF compressor tool, you can reduce the size of PDFs as large as 2 GB, ensuring even large documents are optimised for easy sharing and storage. However, you can usually compress a PDF down to 200 KB if the original file is relatively small—ideally under 1 MB—and mostly contains text. Files with lots of images or complex formatting may not compress that far without losing quality, even with high compression settings.
If you want to further compress a PDF file, you need to reduce the colour depth of the images. However, this will affect the quality of the images. You can also remove unnecessary metadata from the PDF file in order to further reduce file size.
Yes, many online tools and software allow batch compression of PDFs, but whether each file can be reduced to 200 KB depends on its original size and content. Text-heavy files are more likely to meet that target than image-rich ones.
Compressing a PDF to 200 KB usually takes just a few seconds to a minute, depending on the file size or your internet speed.
