Compress PDF

Shrink a PDF that's too big to email or upload — usually by compressing the embedded images, not the text.

What it does

Compress PDF makes a heavy file smaller so it actually fits through the pipe you need to send it through. Most of the weight in a large PDF sits in embedded images — scans, photos, screenshots — so the compressor re-encodes those at a lower resolution while leaving text and vector graphics untouched. The result is a document that still reads sharply but is a fraction of the original size.

How to use it

  1. Upload your PDF file by dragging it into the upload area or clicking to browse your device.
  2. Review the original file size displayed below the upload zone.
  3. Click 'Compress PDF' to start the optimization process.
  4. View the compression results showing original size, new size, and percentage reduction.
  5. Download your compressed PDF — ready to email, upload, or archive.

Key features

Why it helps

Use this when Gmail rejects an attachment over 25 MB, when a tender portal caps uploads at 5 MB, or when a scanned booklet is too large to WhatsApp. Text-heavy PDFs stay razor-sharp; image-heavy files typically drop 50-70%. If size matters more than absolute image fidelity — which is almost always the case for email — this is the last step before you hit send.

Frequently asked questions

How much can the file size be reduced?

Compression can typically reduce file size by 30-70%, depending on the content, especially images.

Will compression affect the quality?

Our tool balances file size and quality. For most documents, the visual difference is negligible.

Can I compress multiple PDFs?

Currently, the tool processes one PDF at a time.

Why should I compress my PDFs?

Compressed PDFs are easier to share via email, upload faster to websites, and take up less storage space.
