About Reduce PDF Size in KB
Portals often say "PDF must be under 200KB". Type that number in the Target size box and the tool compresses your PDF with stronger and stronger levels until it fits.
You can also jump straight to a ready page for the size you need, from 100KB up to 2MB, using the list below. They all use the same compressor.
Each page is turned into a compressed image to reach small sizes, so text in the new file cannot be selected. Your file never leaves your browser.
Frequently asked questions
How do I reduce a PDF to a specific KB?
Choose the PDF, type the size in KB (for example 200) and press Compress PDF. Stronger levels are tried until it fits.
How many KB is 1MB?
1MB is 1024KB. For 2MB type 2048.
Can I keep the text selectable?
Not at small target sizes, because the pages become images. If you only need a modest reduction, choose the Light level and leave the target empty.
Are my files safe?
Everything runs inside your browser, so your files stay on your device and are never uploaded.
