How to Compress a PDF
Reduce PDF File Size with Image Compression
FreeToolIQ can create a smaller PDF by rendering each page and compressing the resulting image. This method can be helpful for scanned documents and image-heavy PDFs.
Choose High Compression for a smaller image resolution, Balanced for everyday documents, or Best Quality when visual clarity matters more than file size.
Results depend on your original PDF. Some files may become larger, especially text-based documents. This process removes the original searchable text layer, so it is not suitable for files that must remain editable, searchable or digitally signed.
Frequently Asked Questions
Is this PDF compressor free?
Yes. No registration is required.
Does compression always reduce PDF size?
No. The result depends on the document and selected quality.
Will the text remain selectable?
No. Pages are converted to images, so the original selectable text is lost.
Are my files uploaded?
No. Your file is processed locally in your browser.
Which compression level should I use?
Start with Balanced. Use High Compression for smaller images or Best Quality for greater visual clarity.
