Why compress PDFs to a custom size?
Many platforms have file size limits – email attachments often cap at 25MB, some portals require files under 200KB, and government websites may ask for PDFs below 50KB or 100KB. Our tool lets you set any target size (minimum 30 KB) and compresses your PDF to that exact limit or smaller, all while keeping quality as high as possible. Plus you see page counts for each file.

FAQs
Absolutely. Enter your target and our tool will compress the file until it's ≤ your target. If the PDF contains heavy images, they will be downscaled just enough to meet the size – you may see some quality reduction, but the file will always be at or below the limit you set.
30 KB. Anything lower is unrealistic for a PDF with text or images.
If a target is set and the file must be heavily compressed, image quality may drop. Text remains crisp. Without a target, compression is lossless.
