A simple way to reduce PDF to 600 KB
See the size first
Each level shows an estimated file size before you compress, so you can pick the one that fits a 600 KB limit without guessing.
Finish without setup
There is nothing to install and no account to create. Upload one file, pick a level, and download the result when it is ready.
Balance photo quality
Large PDF files often get their biggest savings from photos. Our tool seeks a smaller size without compromising clear page content.
Try another reduction
If the file is still too large, upload the compressed copy again and choose a higher level to shrink it further.
Preserve readable type
Text usually stays easy to read at every level. Fine print may soften a little when a file needs strong compression at High.

Frequently asked questions
Will photos keep the file above 600 KB?
They can. Photos often make up most of a PDF's size, so an image-heavy file may stay above 600 KB at Low or Medium. Choose High, which gives the smallest result, and check the estimate. If photos still keep it over, remove the ones the document doesn't need.
What if the PDF is already under 600 KB?
You may not need to reduce the file size if it already meets your target. Further compression can create a smaller copy, but each extra cut may affect images or fine text. Check the current PDF size first, then compress the PDF only when a lower size helps.
Will a file at 600 KB still look fine in print?
Print quality depends on page size, photo detail, fonts, and the amount of PDF compression required. Documents with mostly text may stay clear after you compress PDF files online. Detailed images in PDF files can show more change, so review the downloaded pages before printing.
Can I reduce a PDF to 600 KB for free?
Yes. PDFFly is free to use, with no sign-up and no limit on how many files you compress. Upload your PDF, choose a level by its estimated size, and download the result. You can reduce PDF to 600 KB this way as often as you need.
What happens during PDF file size reduction?
During size reduction, our tool optimizes images in PDF files and removes unnecessary metadata while preserving each document's layout. This process reduces excess data while retaining essential content. The extent of file size change depends on the composition and quality of the original PDF files.
