PDF Compression Guide
Compress PDF Under 1MB Online
Some websites and online forms require PDF files to be under 1MB. This can be difficult if your PDF contains scanned pages, photos, certificates, or multiple documents. Compressing your PDF can help reduce the file size before upload.

PDFs become large when they include high-resolution images, scanned pages, signatures, logos, charts, or multiple combined documents. Even a short PDF can become large if it was scanned at a high quality setting.
How to compress a PDF under 1MB
- Open the PDF compressor tool.
- Upload your PDF file.
- Wait for the compression process to finish.
- Download the smaller PDF file.
- Check the file size before uploading.
What if your PDF is still over 1MB?
If your PDF is still too large after compression, try removing unnecessary pages, reducing image quality before scanning, or splitting the PDF into separate files if the upload portal allows it.
Important tip
Do not over-compress important documents if text, stamps, signatures, or ID details become hard to read.
