HOW IT WORKS

Three steps. That's it.

PDFSize.in is designed to do one thing brilliantly — compress your PDF to exactly the size you need.

01

Upload your PDF

Select or drag and drop your PDF file. We accept files up to 50MB. Your file is immediately sent over an encrypted connection.

02

Choose your target size

Pick from presets — 100KB, 200KB, 500KB, 1MB — or type any custom size in KB. We compress as close to your target as possible while keeping the document legible.

03

Download your compressed PDF

Your compressed PDF is ready in seconds. Download it directly to your device. The file is permanently deleted from our servers immediately after.

A note on compression limits

PDF compression works best on image-heavy documents. Text-only PDFs may already be near their minimum size and cannot be compressed much further. We always maintain document legibility — we will never produce an unreadable file. If we can't reach your exact target, we'll return the best result we can achieve.
